Scope

1.1 These test methods cover procedures for the chemical and gravimetric analysis of white and yellow thermoplastic traffic marking containing lead chromate and titanium dioxide pigment.

1.2 The analytical procedures appear in the following order:

Sections Percent Binder 10 Percent Glass Beads (Note 1) 11 Percent Titanium Dioxide 12 Percent Lead Chromate and Analysis of Chrome Yellow and 13 Chrome Orange Pigments (Note 2)

1.3 This standard does not purport to address all of the safety problems, 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.

Note 1-Test for 1.50 glass spheres only. Note 2-This modified analysis of chrome yellow and chrome orange pigments must be used because the heat resistant chrome yellows in the thermoplastic cannot be analyzed by Test Method D126.
