mesh sieve).
c) For test of polybrominated biphenyls and polybrominated diphenyl ethers, the
treatment method is to pulverize the sample to a particle size of less than 500 μm
(can pass through a 35-mesh sieve).
d) For the bromine release test, the non-test area around the sample shall be wax-
sealed; the area of the sample tested shall not be less than 1 cm2.
5.3.2 Inspection methods for prohibited and restricted substances
5.3.2.1 The asbestos test shall be qualitatively analyzed, according to the provisions of
GB/T 23263.
