Significance and Use | ||||||||||
4.1 This test method provides a means of determining an abrasion rate (weight and calculated average thickness loss) when comparing materials, coatings, pavings, or linings under test conditions that will be subjected to abrasive bed loads. The importance of this information is recognized when dealing with culverts, storm and sanitary sewer applications, although the last two generally do not have the same degree of abrasion due to the flatter slopes and less bed loads than culverts. Specifically, the invert of these types of pipe, regardless of the material used, can be exposed to flows containing abrasive bed loads or solid particulates that cause wearing of the pipe wall. 4.2 By subjecting materials to wear in the bed load abrasion machine with a controlled bed load charge made up of fine aggregate and coarse aggregate over a specified period, a comparison of the resistance between materials can be established. 4.3 This test method does not simulate the effect of abrasive material striking the upstream face of corrugations, as would be typical for coating materials which do not completely fill the corrugations. Note 1: 1.1 This test method covers a procedure
for comparing materials used for coating, paving and lining
corrugated metal pipe by use of a bed load abrasion testing
machine. The procedure attempts to simulate the effect of stone,
gravel and sand carried by a stream through corrugated metal
pipe.
1.2 The values stated in inch-pound units are to be regarded as standard. The SI units given in parentheses are for information only. 1.3 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. |
