Scope
1.1 These test methods cover procedures for the gravimetric analysis of the binder and hydrochloric Acid (HCL) insoluble particles in white and yellow thermoplastic traffic markings. The HCL insoluble particles can be retroreflective optics, such as glass beads or some other type of retroreflective optic, or non-retroreflective particles such as silica sand, or a combination of any two or more of these materials.

1.2 This standard does not address the physical separation and the individual quantification of each component when a mixture of two or more HCL insoluble materials is present. Rather it requires the user to visually evaluate the HCL insoluble material (obtained from following this test method) and report the types of materials present.

1.3 This standard does not purport to address the titanium dioxide or lead chromate pigment measurement (after ashing) which is detailed in Test Methods D1394 and D126.

1.4 This standard will attempt to address the interference of organic pigments with the binder results.

1.5 The analytical procedures appear in the following order:

Sections

Percent Binder

10

Percent Retroreflective Optics or
Non-Retroreflective Particles

11


1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.7 This standard does not purport to address all of the safety concerns, if any......
