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 Binder10
Percent Glass Beads (Note 1)11
Percent Titanium Dioxide12
Percent Lead Chromate and Analysis of Chrome Yellow and Chrome Orange Pigments (Note 2)13

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

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.

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 Methods D 126.


The function of these test methods is to define the percent of binder, glass, titanium dioxide, and lead chromate present in the composition of the thermoplastic traffic marking as defined by the applicable specification for the manufacture of a specific thermoplastic traffic marking.
