ASME: Continued Relevance

An Interview with June Ling, American Society of Mechanical Engineers

The evolving world of standards and standards setting can be better understood through the work and history of the American Society of Mechanical Engineers. June Ling, ASME associate executive director of standards and certification, discusses some of these changes.

ASME codes and standards are used by more than 100 nations around the world. Who uses the codes and how? How do standards strengthen the code?
ASME codes and standards are used (and now developed) throughout the world. They are used by enterprises of all sizes — global corporations and small and medium enterprises in developed and developing nations — and of all types, such as manufacturers, facility owners, plant operators, designers, constructors, inspection bodies, insurers, research institutes, and local and national governments. These latter entities have determined that an ASME code or standard serves as a means of meeting public safety, health and/or environmental objectives within their jurisdictional boundaries. ASME standards have long served as a means of technology transfer and enabling enterprises of all sizes to essentially equally compete in a global market; for owners and insurers they have served as a basis for improved reliability, thereby providing for optimized in-service use and thus lower insurance premiums and casualty losses; and for governments they have served to lessen their burdens in ensuring public safety and quality of life.

A pre-eminent international construction code is the ASME Boiler and Pressure Vessel Code, which comprises 30 individual books covering a wide range of pressure retaining equipment — including power boilers, stationary pressure vessels and transport tanks — and construction and in-service inspection of nuclear power plant components. To adequately address the various aspects of construction, the ASME BPVC references or incorporates standards developed by other organizations; by far the majority consists of ferrous and nonferrous material specifications developed by ASTM International.

The ASME BPVC was first issued in 1914 when state governments, manufacturers, users and insurance interests were faced with significant and frequent losses of life and property from boiler failures and explosions; they came to ASME to develop a uniform set of requirements that would serve to protect the public and reflect a consensus among the differing and competing interests of involved entities. It is this ability to bring together product competitors, the regulated and the regulator, those engaged in research and technology development, and other interested parties that serves to distinguish voluntary consensus standards from standards developed within a company or by a single interest group.

Another ASME code that has gained international usage is our B31 series of piping codes covering power piping; process piping; refrigeration and heat transfer piping; building piping; liquid hydrocarbon pipelines; gas transmission and distribution systems; hydrogen piping and pipelines; pipeline integrity management and personnel qualification. Recently, India took the step of direct adoption of specific ASME B31 codes in their regulations as the result of their assessment that such requirements best serve their needs as India develops its energy infrastructure and its distribution and delivery systems.

I think it is important to note that ASTM International standards have been an essential component of both of these codes as well as of other ASME codes and standards. Materials and test methodologies are an underpinning for the design and fabrication requirements contained in ASME codes and standards. For decades, industry has worked in harmony with ASTM and ASME when incorporating new technology and new materials, and this common effort continues as ASME codes of construction expand globally. One of the challenges both of our organizations face is how to better address local and regional technical needs and how to incorporate the advances of other locales in our standards.

You have long been involved with ASME and its standards work. What changes have you seen in the industry over time? How has ASME responded to those changes?
When I first joined ASME in 1974, executives of industry and research institutes served on ASME standards committees; some companies employed engineers whose only job was standards — their development and their understanding and use within the company — and industry and government participation in ASME was essentially from the United States and Canada. It was also a time of typewriters and carbon paper copies, two-way telephone calls only, and consensus standards development had to be face to face.

As the world has changed, so has stakeholder participation and expectations. Clearly, mergers and acquisitions have had an impact. Users of standards are seeking a single set of consistent requirements that would still provide them with the benefits of technical adequacy while facilitating export and acceptance in all markets and regulatory environments; owners and purchasers seek reduced costs through a wider and dependable supply chain; and governments seek to build their nation’s economy and global competitiveness through standards that best serve these goals. The convergence of technologies and the need for interoperability of systems and components have also led to a blurring of standards coverage and the need for greater collaboration and partnering among standards developers.

ASME has responded through investing in information technology and the development of electronic tools tailored to enable standards development, balloting and communication on a global basis. Additionally, in order to better address technological advances in well-established and regulated environments, ASME supports having both prescriptive and performance-based standards for the same family of products. Examples include the work conducted by ASME and other standards bodies within the International Organization for Standardization (ISO) Technical Committee 11 on Boilers and Pressure Vessels that resulted in a performance-based/essential requirements umbrella standard with a registration process for prescriptive standards from around the world, and the co-existence of prescriptive and performance-based standards within the ASME family of A17 elevator and escalator codes.

With the blurring of technologies, disciplines and borders, joint standards among organizations have also been on the rise. ASME’s longest standing partner has been and continues to be ASTM; more recently ASME has released joint standards with the Canadian Standards Association, the American Petroleum Institute and the American Nuclear Society as well as other U.S. organizations. Under license agreements, several ASME codes and standards have been translated into other languages, adapted for local application and adopted within that nation as industry or national standards. In other locales, the original ASME standards are adopted for use either voluntarily via industry or through mandatory regulatory reference.

As we respond to market and regulatory needs and issues in developed and developing nations, and as we respond to humanitarian needs in underdeveloped nations, ASME’s strategy is to work cooperatively to achieve technical alignment. Our objective is not to be the only standard; it is to reach a level of mutual understanding and technical alignment such that our standard is accepted as equivalent to the relevant national standard or simply accepted as is.

In your view, how has globalization affected the world of standards over the last few decades? What approach has ASME taken with regard to the global application and use of its codes and standards?
In 1972, two years before I joined ASME, there was a significant event that shaped the future direction of ASME codes and standards. In that year, ASME entered into a consent decree with the U.S. Department of Justice in which ASME and the National Board of Boiler and Pressure Vessel Inspectors agreed to make its conformity assessment marks available to all manufacturers, domestic and foreign, on a consistent basis. This was in response to a 1970 Justice Department suit against ASME and the National Board on behalf of manufacturers in Europe who were unable to obtain ASME certification and product marks based on our then-current system of jurisdictional audits/reviews. As many states and provinces required the ASME marks on equipment to be installed and operated within their jurisdiction, the complaint was that the current system posed a restraint of trade. ASME responded, and today ASME has certified more than 6,000 manufacturers in 74 nations. In a way, one could say that equal treatment as delineated in the World Trade Organization Technical Barriers to Trade Agreement has been practiced by ASME since 1972.

Since the early 1900s, use of a common ASME mark for pressure equipment has enabled the interstate/interprovincial commerce of pressure equipment built to a common set of technical requirements. In some respects, the more recent European Union New Approach — with the purpose of furthering a common market among EU nations, enabling placement on the market of equipment meeting a common set of essential safety requirements delineated in directives and EC marking to so designate — parallels what was accomplished in the United States and Canada through the ASME BPVC and its related conformity assessment marks.

Perhaps the most significant response we have made to the global application and use of ASME standards has been to go beyond just use and to seek the actual global development of our standards. Not all of the best minds on the planet speak English, and technology advances are happening throughout the world. Within the past decade, ASME standards participation has expanded beyond participation as an individual expert to include mechanisms such as our delegates program, contributing member appointments, international interest review groups and our latest endeavor of having international ASME committees consisting of local industry based in other nations and conducting ASME committee business locally and in their native language. Examples include an international working group in India on gas pipelines and the just formed international working group in China for nuclear power plant construction.

Science and engineering serve as a universal language, and through ASME’s standard process of openness, transparency, consensus and due process we hope to continue to strengthen our relevancy to national/regional industry and governments.

ASME’s strategic road map focuses on energy, global impact and workforce development. What role will standards have in these initiatives?
ASME has an inspiring mission. It is the same that formed us in 1880, and it is the same that sets our future. While the words have changed over the decades, the essence has remained true to this day. ASME’s mission is to improve the quality of life of all people . . . through engineering.

Standards are an integral component of each of ASME’s strategic priorities. As ASME moves forward in addressing low carbon technologies, from its R&D-based conferences (ASME runs about 40 such conferences per year across a broad spectrum of engineering technologies) through the capturing and dissemination of knowledge gained through industry- and government-funded demonstration and deployment projects, and through state-of-the-art reports, new and updated standards will be an important outcome of the global engineering interactions and exchanges that take place within the space of ASME and its partners.

For ASME, engagement in workforce development is a continuum, beginning with our K-12 (kindergarten through 12th grade) endeavors in STEM (science, technology, engineering and mathematics) education; through university/college engineering and engineering technology curricula accreditation; mechanical engineering department head initiatives; student scholarships, design contests, internships, etc.; and through continuing education courses, training and personnel certification programs for the practicing technical and engineering workforce.

In the past two years, we have also focused on expanding training courses and certificate programs offered by ASME primarily based on technical standards. Initially, such standards will be ASME codes and standards to start, but our end goal is to also cover competitive standards as a service to industry that is faced with meeting numerous standards when supplying to a global market.

ASME continues to extend its global impact through greater understanding, use and actual development of its standards, and related training, product and personnel certifications. More recently, ASME decided to accelerate its global outreach and to invest in positively impacting those billions of people who live on under US$4 a day. This led to the launching of Engineering for Change (E4C) in January 2011 by ASME along with the Institute of Electrical and Electronics Engineers and Engineers Without Borders-USA. In addition to these three founding organizations, two new groups joined the E4C coalition in July as leadership sponsors: the American Society of Civil Engineers and the Society of Women Engineers. E4C is a growing community of engineers, technologists, social scientists, nongovernment organizations, local governments and community advocates whose mission is to improve quality of life in communities around the world by facilitating the development of affordable, locally appropriate and sustainable solutions to the most pressing humanitarian challenges.

What opportunities and challenges for ASME do you see for the future?
I believe the greatest challenge for ASME and its standards work will be remaining technically and globally relevant. Retaining its prominence as a global technical resource will be challenged by the growing complexities of governmental and political influences with setting technology and standards policies; the growing influence and leadership of developing nations in the global market; the changing expectations of new generations; the different market drivers for standards development; the need for faster incorporation of new technologies; and the increasing complexity of the legal landscape (from intellectual property rights related considerations to working within legal infrastructures and frameworks of other nations).

Should we be able to meet this challenge of sustained relevancy, opportunities will be boundless. And, at the end of the day, ASME will have served its mission in partnership with the global community, and at the same time, grow in size and reputation.

ASME and ASTM International have worked cooperatively for many years. How would you characterize that cooperation? How has it benefited standards setting?
Both ASME and ASTM grew out of the industrial revolution in the United States, and our endeavors have been and will continue to be in accord with one another. Our respective organizational objectives align well and while our scope of endeavors may have changed over time, for example, the broadening of ASTM’s scope of coverage beyond material specifications and testing methods, and the deepening of ASME’s scope of coverage as technology has grown in complexity, our organizations continue to find common ground for cooperative endeavors on a regular basis. On a personal level, I know of no better or closer relationship than the one that has grown and developed between ASME and ASTM staff over the decades. There have been many occasions where the words of Jim Thomas have echoed in my thinking; I hold a boundless respect for Jim Thomas and his staff and share in his passion, respect and vision for our respective organizations.

You have been honored with the ASME Melvin R. Green Codes and Standards Medal as well as the ASTM International William T. Cavanaugh Memorial Award. What do these awards mean to you, as you worked with both Cavanaugh and Green?
I am deeply humbled and honored to be a recipient of both of these awards, especially because of the personal connection to both gentlemen. I worked for Mel Green from my first day at ASME until his retirement in 1995. When I received the Melvin R. Green Codes and Standards Medal I knew I was accepting the medal on behalf of the ASME codes and standards staff, most of whom were hired under his watch and who learned much from him about the impact and power of consensus standards and the importance of protecting the integrity of the process. I didn’t have the privilege of having as close of an association with Bill Cavanaugh, but his presence and written communications conveyed a spirit and passion as strong as Mel’s, and the stories Mel would share were as entertaining and humorous in the telling as they were enlightening and educational in their substance.

When I received the William T. Cavanaugh Memorial Award in 2003, I was thrilled by the high distinction bestowed but quickly realized that it was not for any personal achievements but more along the same lines of achievements accomplished through the collaborative endeavors of both ASTM and ASME.

Both Mel Green and Bill Cavanaugh had a way of mentoring that was not obvious to those being mentored; only in retrospect did I realize how much they influenced my thinking and thus my actions. They placed their organization and public safety mission ahead of any personal benefit; this they did time and time again without mention or hesitation. I also remember the laughter during good times and during stressful times, and I need to remind myself that such laughter is an important way to ensure the next generation finds the work of standards an enriching experience.

Mentoring is important in the standards world. This is especially true for ASME and ASTM as our system for the development of international standards is not the norm in the rest of the world. Many of the issues surrounding standards cannot be properly addressed by a surface or cursory understanding of standards per se; one size does not fit all when it comes to what best serves the needs of a specific industry or market condition, and the need for those with a robust understanding of the impact of standards on innovation, trade and commerce, quality of life, and the inherent benefits and pitfalls of standards will only increase as the world shrinks, flattens or goes world-about (as Mel would say) again.
