Aperçu de conformité

Cet aperçu n’est actuellement disponible qu’en anglais.

Champ d’application

This standard applies to musical instruments, musical instrument accessories, and indoor musical instrument packaging. It categorizes products into Class A (direct oral contact) and Class B (non-oral but human-accessible contact). Manufacturers of these products must comply with these mandatory requirements to enter the Chinese market. It is not applicable to packaging materials that are not placed indoors.

Exigences techniques

The standard specifies strict limits on various hazardous substances to ensure user safety. For products using plastic materials, it regulates the maximum allowable concentration of phthalates, including DEHP, DBP, and BBP. Compliance with these chemical limits is essential for product certification. Additionally, the standard introduces new requirements for polycyclic aromatic hydrocarbons (PAHs), specifically limiting Benzo[a]pyrene and total PAHs. It also sets thresholds for migratable elements such as lead, chromium, and cadmium in accessible parts, referencing test methods similar to GB 6675.4-2014. For materials like wood, textiles, and coatings, the standard restricts the emission of volatile organic compounds (VOCs), benzene series, and formaldehyde. It also prohibits the use of aromatic amine dyes and sets limits for pentachlorophenol (PCP) and tetrachlorophenol (TeCP) in specific materials. Suppliers must ensure all raw materials meet these updated environmental thresholds. Furthermore, electronic components in electro-musical instruments must comply with RoHS-like requirements, restricting substances like lead, mercury, and cadmium, in accordance with GB/T 26572-2011. Natural radioactive nuclides in stone or ceramic materials are also regulated.

Méthodes d’essai

Testing involves various standardized methods to verify compliance. Phthalates are tested according to GB/T 22048, while PAHs follow GB/T 40968. Migratable elements are extracted simulating gastric acid contact and analyzed per GB 6675.4-2014. VOCs and formaldehyde are tested using a climate chamber method to simulate indoor release environments. Aromatic amines, TeCP, and PCP are tested using referenced textile and leather testing standards like GB/T 17592 and GB/T 22808.
