1 Scope
This document specifies the limits and test methods of harmful substances in non-
metallic materials, which are used in railway locomotive and vehicle, the limits and test
methods of prohibited and restricted substances in non-metallic materials, which are
used in railway locomotive and vehicle, as well as the limits and test methods of harmful
substances in indoor air of railway locomotive and vehicle.
This document applies to the limits of harmful substances in non-metallic materials for
locomotives, passenger trains, EMUs; the indoor air of driver's cabs and passenger
compartments; the limits of prohibited and restricted substances of non-metallic
materials for locomotives, passenger trains, EMUs.
2 Normative references
The contents of the following documents constitute essential provisions of this
document through normative references in the text. For the dated documents, only the
versions with the dates indicated are applicable to this document; for the undated
documents, only the latest version (including all the amendments) is applicable to this
standard.

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.
5.3.2.2 For the test of Chlorofluorocarbons (CFC), Perbromofluorocarbons (HALON),
Hydrochlorofluorocarbons (HCFC), Hydrofluorocarbons (HFC), Perfluorocarbons
(PFC), sulfur hexafluoride (SF6), tetrachloroethylene, they are carried out, in
accordance with the provisions of Appendix D.
5.3.2.3 For the test of arsenic and its compounds, antimony and its compounds,
beryllium and its compounds, cobalt and its compounds, it shall be carried out
according to the provisions of GB/T 33422. For the test of antimony and its compounds,
it is recommended to add an appropriate amount of hydrochloric acid to the sample
digestion reagent. If the sample is glass or ceramics, use 5 mL of concentrated HNO3 +
1.5 mL of HF + 1.5 mL of H2O2 as the digestion reagent; the rest of the sample digestion
reagents shall be carried out, according to GB/T 33422. The test results shall be based
on the content of metal elements. The detection limit of beryllium and its compounds,
cobalt and its compounds are 5 mg/kg.
5.3.2.4 For the test of cadmium and its compounds, lead and its compounds, mercury
and its compounds, polybrominated biphenyls and polybrominated diphenyl ethers, it
shall be carried out, according to the provisions of GB/T 26125.
5.3.2.5 For the test of hexavalent chromium compounds, if the sample is leather, it shall
be carried out, in accordance with the provisions of GB/T 22807; if the sample is of
other materials, it shall be carried out, in accordance with the provisions of GB/T 26125.
5.3.2.6 The test of 4-nitrobiphenyl shall be carried out, according to the provisions of
Appendix E.
5.3.2.7 For the test of 2-naphthylamine, p-diaminodiphenyl, 4-aminobiphenyl, if the
sample is textile, it shall be carried out, according to the provisions of GB/T 17592; if
the sample is leather, it shall be carried out, according to the provisions of GB/T 19942;
if the sample is made of other materials, the sample processing method is as follows:
Accurately weigh 1 g of the sample, accurate to 0.01 g; put it in a sample bottle; add 10
mL of methanol, to ultrasonically extract it in a 60 °C water bath, for 60 min; cool to
room temperature; use a 0.22 µm filter membrane for filtering; carry out test according
to the analytical method of GB/T 17592.
