6 Test methods
6.1 Delivery moisture
It is determined according to the provisions of GB/T 462.
6.2 Heavy metals
Lead (Pb) is determined according to the provisions of GB/T 24991, chromium (Cr) is
determined according to the provisions of GB/T 24990, mercury (Hg) is determined
according to the provisions of GB/T 22804, cadmium (Cd) is determined according to
the provisions of GB/T 24997. Microwave digestion method is used for pretreatment.
Lead (Pb), chromium (Cr) and cadmium (Cd) can also be determined according to the
provisions of GB 31604.49. In case of arbitration, it is determined according to the
provisions of GB 31604.49. The sum of the determined values of the 4 heavy metals is
the total amount of heavy metals (Pb, Cr, Hg, Cd).
6.3 Polybrominated biphenyls and polybrominated diphenyl ethers
It is determined according to the provisions of GB/T 26125.
6.4 Organically bound chlorine
It is determined according to the provisions of GB/T 22904.
6.5 Phthalates
It is determined according to the provisions of GB/T 37860.
7 Inspection rules
7.1 The manufacturer shall ensure that the pulp molding products produced meet the
requirements of Clause 5. The delivery quantity of pulp molding products continuously
produced with the same specifications, the same raw materials, and the same process is
one batch, and each batch shall not exceed 10 thousand.
7.2 The counting sampling inspection procedure is carried out according to the
provisions of GB/T 2828.1. The sample unit of pulp molding products is a box or a
bundle. Acceptance quality limit (AQL): AQL = 4.0 for heavy metals, polybrominated
