Limits for lead, cadmium, hexavalent chromium,
mercury in plastic materials
1 Scope
This Standard specifies limit indicators and inspection methods for lead (Pb),
cadmium (Cd), hexavalent chromium [Cr(VI)], mercury (Hg) in plastic materials.
This Standard is applicable to all kinds of plastic materials, masterbatches and
their products, including baby products, food contact materials, electronic and
electrical products, automobile products, furniture products, and general plastic
products.
2 Normative references
The following referenced documents are indispensable for the application of
this document. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any
amendments) applies.
GB/T 2035, Terms and definitions for plastics
GB/T 38287, Determination of hexavalent chromium in plastic materials
GB/T 38290, Determination of cadmium in plastic materials
GB/T 38291, Determination of lead in plastic materials
GB/T 38292, Determination of mercury in plastic materials
3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T
2035 as well as the followings apply.
3.1 plastic
a macromolecular organic compound that is obtained by polymerization,
polycondensation, addition polymerization or any other similar process to make
small molecular organics or chemically change the properties of natural
macromolecular organics
NOTE: According to chemical composition, it is divided into polyethylene (PE),
polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), ABS resin, polycarbonate
(PC), polyethylene terephthalate (PET), polyamide (nylon PA), vinylidene chloride resin
(PVDC), melamine (PM).
3.2 plastic materials
a polymer material that takes one or several plastics (prepolymer or resin) as
the main structural component, with or without additives, to be processed at a
certain temperature and pressure, so as to make it have a certain shape and
between resin and plastic product
NOTE: Include plastic particles (or slices), masterbatches, sheets.
3.3 masterbatch
a concentrate that is made by excessively LOADING plastic additives (such as
colorants, fillers, fibers, stabilizers) which affect the physical properties of
plastic materials and products INTO one or more resins, that can be mixed with
resin or pellets so as to be processed into other plastic materials and final
products
3.4 plastic product
a molded product that uses plastic resin or plastic materials as raw materials,
with or without additives, to be molded into a certain shape
3.5 limiting value
the maximum allowable level of lead, cadmium, hexavalent chromium, and
mercury in various plastic materials, masterbatches and their products
4 Principles of application
For products of specific purposes, if there are special requirements on the
limiting values of lead, cadmium, hexavalent chromium and mercury, it shall
refer to their regulations.
5 Requirements
The limiting values of lead, cadmium, hexavalent chromium and mercury in
plastic materials shall meet the requirements of Table 1.
