These test methods cover production and acceptance tests for concrete pipes, manhole sections, and tiles. Tests include procedures for evaluating external load crushing strength, flat slab top, core strength, absorption, hydrostatic, permeability, manhole step, cylinder, gasket lubricant, joint shear, alkalinity, and gasket measurements. Aside from the procedures, this standard also details the significance and use of and the required test apparatus for each test.

1.3 The test specimens shall not have been exposed to a temperature below 4°C for the 24 h immediately preceding the test.
1.4 If any test specimen fails because of mechanical reasons such as failure of testing equipment or improper specimen preparation, it shall be discarded and another specimen taken.
1.5 Specimens shall be selected in accordance with the specifications for the type of pipe or tile being tested.
1.6 These methods are the metric companion of Test Methods C497.
1.7 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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
