    Significance and Use

    4.1 Operational experience and independent testing have fully documented that the usable life, maintenance and failure and mean time between failures (MTBF) in buried storm and wastewater lines can be directly affected by the defects during manufacturing, incorrect pipe storage, and improper installation, including improper compaction often resulting in the deformation (Ovality or shape, or both) and physical damage in newly installed, repaired and replaced pipelines. Laser profiling assessment is an effective quality control tool for identifying and quantifying deformation, physical damage, and other pipe anomalies after installation, providing valuable means and methods for determining the quality of workmanship and compliance with project specifications. Laser profiling can be used for:

    4.1.1 Measurement of the structural shape, cross sectional area and defects;

    4.1.2 Collection of data needed for better pipe rehabilitation or replacement design; and

    4.1.3 Post rehabilitation, replacement or new construction workmanship verification.

    4.2 This standard practice provides minimum requirements on means and methods for laser profiling to meet the needs of engineers, contractors, owners, regulatory agencies and financing institutions.

    4.3 A laser profile pre-acceptance and condition assessment survey shall provide significant information in a clear and concise manner, including but not limited to graphs and still frame digital images of pipe condition prior to acceptance, thereby providing objective data on the installed quality and percentage ovality, deformation, deflection or deviation, that is often not possible from an inspection by either a mandrel or CCTV only survey.

    4.4 This practice applies to gravity flow or depressurized lines–storm sewers, sanitary sewers, combined sewers, siphons, edge drains, highway drains, and culverts, and to all other pipelines, ducts and conduits that are made accessible and meet the requirements of 1.3, regardless of shape, design, configuration or material (smooth or corrugated). The line shall be free of excess debris and obstructions with a maximum flow level or stagnant water, during laser profiling, not to exceed 10 % of nominal pipe diameter or 6 in. in depth, whichever is the lesser.

    1. Scope

    1.1 This practice covers the procedure for the measurement to determine any deviation of the internal surface of installed pipe compared to the design. The measurements may be used to verify that the installation has met design requirements for acceptance or to collect data that will facilitate an assessment of the condition of pipe or conduit due to structural deviations or deterioration.

    1.2 This practice applies to all types of pipe material, all types of construction, and pipe shapes.

    1.3 This practice applies to depressurized and gravity flow storm sewers, drains, sanitary sewers, and combined sewers with diameters from 6 to 72 in. (150 and 1800 mm). The pipe shall be precleaned and free of debris that would prevent the CCTV camera and laser projector assembly, shown in Fig. 1, from moving through the pipe, or adversely affect the accuracy of the survey. Flow or debris, within the line, shall be less than 10 % of the nominal pipe diameter or 6 in. in depth whichever is the lesser.

    1.4 The laser light projector shall be tested, labeled and certified to conform to US requirements for CDRH Class 2 or below (not considered to be hazardous) laser products or certified to conform to EU requirements for Class 2M or below laser products as per IEC 60825-1, or both.

    1.5 The profiling process may require physical access to lines, entry manholes and operations along roadways that may include safety hazards.

    1.6 This standard does not include all aspects of pipe inspection; for example the following are not covered by this standard: joint gaps, soil/water infiltration in joints, cracks, holes, surface damage, repairs, corrosion, and structural problems associated with these.

    1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. There are no safety hazards specifically, however, associated with the use of the laser ring profiler specified (listed and labeled as specified in 1.3).
