1. Scope 1.1 This test method is used to determine the adherent coating on coarse aggregate (aggregate retained on the 2.36-mm (No. 8) sieve) for the following purposes 1.1.1 Preliminary investigation of mineral aggregate sources. 1.1.2 Control of mineral aggregates used in hot mix ...
The particle size distribution of a metal powder affects its behavior in P/M processing and other applications of these materials. The test method may be part of the purchase agreement between powder supplier and user, or it may be an internal quality control test for either. 1. Scope 1.1 This test method covers the dry sieve analysis of metal powders or mixed ...
Plastic materials, when used as transparencies, covers, or enclosures, are subject to wiping, cleaning, or other types of rubbing actions that cause abrasion. It is the intent of this test method to provide a means of estimating the resistance of such materials to this type and degree of abrasion. 1. ...
This test method develops a measurement of grinding or pulverizing characteristics that can be used to evaluate the yield, or energy input, or both, required in a grinding or pulverizing process, which can impact a wide variety of processes, including combustion, coke-making, liquefaction, and gasification. 1. Scope 1.1 This test method covers the determination of the relative ...
The amount of asphalt absorbed by the aggregate contributes little or nothing to the durability of an asphalt pavement in service other than possibly providing greater resistance to stripping in the presence of water. Percent asphalt absorption can be an indicator of changes that may occur in plant mix production during construction. The calculated percent ...

This specification covers the standards for the quality and grading of crushed stone, crushed slag, and water-worn gravel intended for use as coarse mineral aggregate on built-up roofs. The crushed stone and gravel shall be hard, durable, opaque, and free of foreign substances. The crushed slag, on the other hand, shall be hard, air-cooled, and free of as well of any foreign ...
Sieves are used in many laboratories for analysis of solid materials particle size distribution. It’s important to make sure the sieve you are using has an accurate, calibrated mesh to ensure your results are correct, but did you know that different levels and classifications of certification are available? Endecotts sieves offer the high quality and accuracy needed for laboratory sieve ...
