Escopo e aplicabilidade

This standard applies to medical gloves including single-use rubber examination gloves, sterile rubber surgical gloves, nitrile rubber examination gloves, PVC examination gloves, and non-sterile rubber surgical gloves. It is specifically designed for products manufactured from natural rubber latex and other materials where powdering is used. Manufacturers of these medical devices must comply with these limits to sell in the Chinese market.

Requisitos técnicos

The standard specifies the maximum allowable limits for removable surface powder and water-extractable protein on medical gloves. Clause 4.1 and 4.2 are mandatory requirements. For gloves made from natural rubber latex, the standard sets a strict limit on the content of water-extractable proteins to prevent allergic reactions. Additionally, it distinguishes between powdered and powder-free gloves, establishing separate maximum thresholds for residual powder on the glove surface. Compliance with these specific numerical limits is mandatory for all applicable medical gloves. The standard references ISO 21171:2006 and ISO 12243:2003 for relevant testing methodologies.

Métodos de ensaio

Testing for water-extractable protein content in natural rubber latex gloves must be conducted according to the modified Lowry method specified in GB/T 21870-2008 (Method A). The determination of removable surface powder is performed according to GB/T 21869-2008, which involves calculating the total surface area of the glove based on measured width and length to determine the powder concentration per unit area.
