Section 173-901-100. Environmental compliance marking.

(1) What is the environmental compliance marking? The environmental compliance marking is the last letter or last two letters in the unique identification code marked on brake friction materials. It must be an "A," "B," "N," "WX," or "X" and it allows a person to determine the level of environmental compliance of the brake friction material.

(2) What does the environmental compliance marking "A" indicate? An "A" indicates that the brake friction material manufacturer has submitted self-certification documentation and laboratory testing results showing the brake friction material does not contain any of the following regulated constituents in amounts exceeding the specified concentrations:

(a) Asbestiform fibers, 0.1 percent by weight;

(b) Cadmium and its compounds, 0.01 percent by weight;

(c) Chromium (VI)-salts, 0.1 percent by weight;

(d) Lead and its compounds, 0.1 percent by weight; or

(e) Mercury and its compounds, 0.1 percent by weight.

(3) What does the environmental compliance marking "B" indicate? A "B" indicates that the brake friction material manufacturer has submitted self-certification documentation and laboratory testing results showing the brake friction material does not contain any of the compounds listed in subsection (2) of this section in amounts exceeding the specified concentrations and that the brake friction material contains between .5 and 5 percent copper by weight.

(4) What does the environmental compliance marking "N" indicate? An "N" indicates that the brake friction material manufacturer has submitted self-certification documentation and laboratory testing results showing the brake friction material does not contain any of the compounds listed in subsection (2) of this section in amounts exceeding the specified concentrations and that the brake friction material contains less than .5 percent copper by weight.

(5) What does the environmental compliance marking "WX" indicate? A "WX" or "X" indicates that the brake friction material has been granted an exemption from certain requirements of chapter 70.285 RCW and this chapter, under WAC 173-901-140, it is designed for use on a vehicle that is not required to meet the requirements of chapter 70.285 RCW and this chapter, or is manufactured as part of an original equipment service contract. A brake friction material marked with a "WX" or "X" may only be installed on the vehicles or type of vehicles for which it is designed. It must not be installed on a vehicle that is required to comply with chapter 70.285 RCW and this chapter.
