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.
