Champ d’application

GB 27949-2020 applies to chemical disinfectants used for the disinfection and sterilization of medical instruments. This standard is mandatory for all manufacturers of such products. It is explicitly not applicable to disinfection equipment with built-in disinfection factor generators, nor to gaseous or vaporized disinfection and sterilization products. It covers requirements for raw materials, technical specifications, testing methods, usage, labeling, packaging, storage, and transportation.

Exigences techniques

This standard specifies the mandatory technical requirements for chemical disinfectants used on medical instruments. Key areas include raw material requirements, which must comply with the Pharmacopoeia of the People's Republic of China and relevant national standards. The standard sets limits for physicochemical indicators such as active ingredient content and pH values. Manufacturers must ensure a minimum shelf life of 12 months with no significant changes in sensory and pH indicators. It also mandates corrosion resistance testing, requiring that disinfectants used on metal instruments show no or only mild corrosion to stainless steel, carbon steel, aluminum, and copper. Additionally, the standard outlines microbicidal efficacy requirements categorized by sterilization, high-level, intermediate-level, and low-level disinfection, without detailing the specific log reduction values in this summary. It also includes requirements for continuous use stability and toxicological safety, demanding that disinfectants be practically non-toxic or low-toxic and non-mutagenic.

Méthodes d’essai

Testing methods are primarily based on the Technical Standard for Disinfection (2002 edition) and other relevant national standards. The standard outlines procedures for evaluating physicochemical indicators, microbicidal efficacy (using both suspension and carrier methods), metal corrosion, and continuous use stability. For endoscope disinfectants, testing references the Technical Specification for Inspection of Disinfection Efficacy of Endoscope Cleaning and Disinfection Machines. Manufacturers must validate both laboratory and simulated field test results to ensure compliance with the specified efficacy tiers.
