§ 66387.6. Testing Methodology and Maximum Concentrations of Regulated Constituents and Copper for Brake Friction Materials.
The analytical laboratory is responsible for the accuracy of the test results reported to the testing certification agency. The manufacturer of brake friction material is responsible to confirm the concentrations of regulated constituents and copper reported correspond to the concentrations known to be in their brake friction material formulations prior to the analytical laboratory reporting these testing results to the testing certification agency.
To be used for certification, the cumulative average of all testing data must show that the brake friction material does not exceed the following concentrations:
All testing for the regulated constituents and copper must be done at least in triplicate.
(1) Due to the margin of error in the test method, additional testing may be required to demonstrate that the brake friction material does not exceed the concentrations listed for each of the regulated constituents and copper in Health and Safety Code sections 25250.51, 25250.52, and 25250.53. Cumulative average of all testing results conducted on a specific brake friction material must meet the applicable requirements of the subsection (d) of this section.
(A) For example, if a pad contains 4.9 percent copper, the first round of testing results could come back showing the average testing result is greater than 5.0 percent copper by weight. Consequently, these results would not be suitable for demonstrating compliance and the brake friction material would need to be retested in accordance with SAE J 2975:DEC2013.
No results are reported to the Department.
The analytical laboratories shall transmit all laboratory testing results for a brake friction material directly to a testing certification agency.
(1) Test results determined to be laboratory error as specified in section 66387.6 subsection (h) do not have to be reported to the testing certification agency. All test results derived from a single set of friction material samples must be reported to the testing certification agency at the same time on a single report.
(A) If an alternate method of testing approved under subsection (l) of this section is used to perform testing and that alternate method specifies the minimum reporting information, then test reports transmitted from the laboratory to the testing certification agency shall include the minimum information specified in the alternate method of testing utilized.
(3) In addition to reporting the cumulative average for each regulated constituent and copper listed in this subsection, the testing laboratory shall perform a comparison between the cumulative average and the concentrations listed under this subsection and specify the environmental compliance level indicated by the report. This comparison shall report whether the cumulative average concentration does not exceed the following concentrations:
If laboratory error is suspected, the laboratory may, at its discretion and in accordance with its standard operating procedures, choose to retest the brake friction material. The results from the testing in which the error occurred do not need to be included in the testing results transmitted to the testing certification agency.
(2) If the laboratory previously submitted results to a testing certification agency and later determines any of those results were laboratory error, then the laboratory shall inform the testing certification agency within four (4) calendar days of the determination that the test results were laboratory error. The testing certification agency shall withdraw registration of specific unique identification codes until such time as new testing without laboratory error is properly provided to the testing certification agency which warrants the unique identification codes being properly registered.
A manufacturer of brake friction materials shall maintain copies of laboratory testing results for a period of at least ten (10) years after the date of self-certification.
A manufacturer of brake friction material may use an alternative testing method if the alternative testing method is approved by the Department under subsection (k) of this section, in advance of use for self-certification. Once an alternative testing method has been approved by the Department, any manufacturer of brake friction material may use the approved alternative testing method for certification. The Department shall only approve an alternative testing method:
An entity may submit a request for approval on an alternative testing method in writing or electronically. The request must include the following information:
(A) For an electronic submittal, a person shall send the request to the Department via electronic mail ([email protected]) on the Department's website at http://www.dtsc.ca.gov with the words “Attention: California Brake Pad Alternative Testing Method Request” displayed in the subject line of the electronic mail; or
(B) For a written submittal, a person shall send the request to the Department via certified mail, return receipt requested, at the following address: Department of Toxic Substances Control, Safer Products and Workplaces Program, P.O. Box 806, Sacramento, CA 95812-0806, with the words “Attention: California Brake Pad Alternative Testing Method Request” prominently displayed on the front of the envelope.
The Department shall notify the manufacturer of brake friction material, testing certification agency, or testing laboratory in writing whether the alternative testing method was approved within 90 days of receiving the request. If the Department finds the alternative testing method is equivalent to or better than SAE J 2975:DEC2013 the Department shall provide the basis of the approval. If the Department does not find the alternative testing method equivalent to or better than SAE J 2975:DEC2013 the Department shall provide the basis for the denial. The alternative testing method approved by the Department shall be posted on the Department's Web page at http://www.dtsc.ca.gov.
