Compliance overview
Scope and applicability
This standard specifies the selection, use, maintenance, and disposal/replacement of chemical protective clothing. It applies to chemical protective clothing used by workers in operational environments and emergency response activities. It is mandatory for manufacturers and users of chemical protective equipment in China. It covers various types of protective clothing including gas-tight, liquid-tight, and particulate protective suits, as well as partial body protection.
Technical requirements
The standard outlines comprehensive requirements for the selection, use, and maintenance of chemical protective clothing. Hazard assessment is a critical first step, requiring evaluation of chemical properties, environmental conditions, and worker characteristics. The standard classifies protective clothing into several types based on protection levels: Type 1 (gas-tight), Type 3 (liquid jet tight), Type 4 (liquid spray tight), Type 5 (particulate), and Type 6 (limited liquid spray), along with specific variants for emergency response teams (ET). Selection criteria are based on the state of the chemical hazard (gas, liquid, solid, particulate) and the required performance level of the clothing. Performance evaluation includes fabric chemical resistance (repellency, permeation resistance, penetration resistance) and physical-mechanical properties (abrasion resistance, flex cracking, puncture resistance, tear strength). Users must select clothing where the normalized breakthrough time exceeds the expected exposure time. The standard also details requirements for reusable versus limited-use clothing, emphasizing that reusable suits must undergo decontamination and assessment before reuse. Maintenance protocols include proper repair, decontamination procedures, and storage conditions to ensure the clothing remains in a reliable state. Finally, it specifies criteria for disposal and replacement, mandating that clothing be discarded if it fails inspection, exceeds its expiration date, or loses functionality.
Testing methods
The standard references testing methods primarily from GB 24539-2025 for evaluating chemical protective clothing performance. Key tests include: fabric liquid repellency testing, chemical permeation resistance testing, and hydrostatic penetration resistance testing. Physical-mechanical tests assess abrasion resistance, flex cracking resistance, puncture resistance, and tensile/tear strength. Overall garment integrity is verified through gas-tightness, liquid jet tightness, liquid spray tightness, or particulate inward leakage tests, along with seam strength testing.
FAQs
What products are regulated under GB 24536-2025?
GB 24536-2025 regulates the selection, use, and maintenance of chemical protective clothing used in workplaces and emergency response, including gas-tight suits, liquid-tight suits, particulate protective clothing, and partial body protection items like aprons and sleeves.
Are there any updates from the previous version of GB 24536-2025?
Yes, compared to GB/T 24536-2009, the 2025 version adds requirements for disposal and replacement, updates terminology and definitions, revises the classification and codes for chemical protective clothing, and adds detailed descriptions of protection performance levels and selection principles for reusable and limited-use clothing.
How does GB 24536-2025 relate to other standards?
This standard references GB 24539-2025 for the technical requirements and testing methods of chemical protective clothing, GBZ 2.1 for occupational exposure limits of hazardous chemical factors, and GB/T 16483 for safety data sheets (SDS) of chemical products.
