(Test Method)Standard Test Method for Sieve Analysis of Glass Spheres
Standard Test Method for Sieve Analysis of Glass Spheres
SIGNIFICANCE AND USE
The size or gradation of glass spheres is one measurable aspect of performance as a retroreflective media. The function of this test is to measure the size of glass spheres and to determine compliance with applicable specifications.
Note 1—This method has been used in other industrial areas outside the intended scope of this test method.
SCOPE
1.1 This test method covers the sieve analysis of glass spheres used for retroreflective pavements markings and industrial uses.
1.2 The values stated in SI units are to be regarded as the standard. The values 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.
