1022.4 Laboratory Testing Guidelines for Sec 1022

This article establishes procedures for Laboratory testing, reporting and accepting corrugated metallic-coated steel pipe underdrain material.

1022.4.1 Procedure

Laboratory tests to be performed on the sample are designated by the inspector in the remarks area of AASHTOWARE (AWP). Normally, the only Laboratory tests required are weight of coating on each sample and chemical analysis approximately once a year. If two samples from different districts are submitted for chemical analysis within a period of one month from the same manufacturer and base metal, only one sample need be tested.

1022.4.1.1 Chemical Tests

The procedure for determining weight of coating shall be according to AASHTO T65 for zinc coated and T213 for aluminum coated. Mass of coating shall be reported as ounces per square foot (kg/sq meter), double exposed surface. Chemical composition of the base metal shall be determined according to the methods set forth in EPG 1020.8.1.1 Chemical Tests. Original test data and calculations shall be recorded in Laboratory workbooks. Test results shall then be recorded through AWP.

1022.4.1.2 Physical Tests

When requested, gage or thickness shall be determined with a micrometer graduated in increments of 0.0001 in. (.00254 mm). A minimum of five thickness measurements are to be made on the tangents of corrugation at least 3/8 in. (9.5 mm) from the edge of metal. Both the minimum and average thickness results shall be reported to 0.001 in. (.0254 mm). All test results shall be recorded through AWP.

1022.4.2 Sample Record

The sample record shall be completed in AASHTOWARE Project (AWP) in accordance with AWP MA Sample Record, General, and shall indicate acceptance, qualified acceptance, or rejection. Appropriate remarks, as described in EPG 106.20 Reporting, are to be included in the remarks to clarify conditions of acceptance or rejection. Laboratory and field test results shall be reported in the appropriate templates under the Tests tab.
