ASTM WK62898

New Specification for Standard Specification for Low-Relaxation, Hot Dip Galvanized, Seven-Wire Steel Strand for Post Tensioning or Reinforcing Concrete Structures

1. Scope

The promotion of knowledge, the stimulation of research, and the development of specifications, test methods, terminology, and other types of standards relating to cast or wrought steels, stainless steels and related alloys and ferrous alloys.

Areas of Interest: The Committee's interest includes the following materials: carbon and alloy steels, tool steels, tin mill products, corrosion and heat-resistant alloys, super-strength alloys, and clad steels.
The Committee, unless specifically requested by the Chairman of the Committee having prime responsibility, is not concerned with materials which are the interest to Committees; A06 on Magnetic Properties, B02 on Nonferrous Metals and Alloys, B04 on Metallic Materials for Thermostats and for Electrical Resistance, Heating, and Contacts; and F04 on Surgical Implants.

The Committee specifically excludes the following areas of interest:
* Aluminum-coated, zinc-coated, or terne-coated steel products covered by Committee A05.
* Alloys in those forms for which the principal use results from specifically controlled electrical resistance, thermal expansion, or magnetic characteristics which pertain to electrical resistance devices, electrical contacts, thermostats, and electrical steel.
* Materials for surgical implants.

Policy on Material Specification Coverage: The material specifications prepared by the Committee are available for use by producers and users anywhere in the world. To maintain a practical limit to the amount of committee effort, the Committee will prepare and administer specifications within its expertise. Requests for new specifications or standards or for new grades or types of material should be supported by a regulatory body, a code-writing body or a member of ASTM.


galvanized strand; Grade 270 [1860] strand; hot-dip galvanizing; metallic-coated steel wire; seven-wire metallic-coated strand; zinc-aluminum alloy galvanized steel wire; zinc-aluminum alloy galvanized steel strand :


Currently, there is not an ASTM standard for galvanized PC strand as there is in the EU. ASTM A416 only covers uncoated strand for these applications. The objective of this standard is to establish a standalone specification for this product that is similar in strength and design requirements as ASTM A416 uncoated 270K PC strand.

The title and scope are in draft form and are under development within this ASTM Committee.
