적용 범위

This standard applies to protective gloves designed to safeguard against mechanical hazards, including abrasion, cutting, tearing, puncture, or impact. It is mandatory for all manufacturers producing mechanical risk protective gloves for the Chinese market. The standard does not apply to gloves intended solely for protection against sharp objects like syringe needles, as noted in the document. It replaces the previous version, GB 24541-2009.

기술 요구 사항

The standard specifies the minimum performance levels for mechanical hazard protection. Gloves must meet the general requirements of GB 42298-2022 and achieve at least Level 1 for abrasion, tear, and puncture resistance. For cut resistance, gloves must meet at least Level 1 using the circular blade method or Level A using the straight knife method. For impact protection, gloves claiming this feature must withstand a 5J impact energy. The transmitted force must not exceed 9.0 kN for a single impact and 7.0 kN on average. Marking requirements dictate the use of a specific pictogram displaying five performance levels. If the glove passes the impact protection test, the code "P" must be added. Manufacturers must also provide detailed user instructions, including warnings for multi-layer gloves and entanglement risks.

시험 방법

The standard outlines several key testing procedures to evaluate glove performance: - Abrasion resistance: Tested using the Martindale method with specific abrasives and double-sided tape. - Cut resistance (Circular blade): Uses a rotating circular blade against the sample, calculating a cut index. - Cut resistance (Straight knife): Measures the cutting force required to cut through the sample, used for high-cut-resistant materials. - Tear resistance: Evaluated using a tensile testing apparatus to measure the force required to tear the material. - Puncture resistance: Measures the maximum force required for a standard steel nail to penetrate the glove. - Impact protection: Assesses the glove's ability to absorb a 5J impact using a drop hammer and force sensor.

자주 묻는 질문

What products are regulated under GB 24541-2022?

It regulates protective gloves designed to protect against mechanical risks such as abrasion, cutting, tearing, puncture, and impact.

What are the main updates from GB 24541-2009?

The 2022 version introduces the straight knife test method for cut resistance, adds impact protection requirements, and updates marking and manufacturer information guidelines.

How is impact protection tested and marked?

Gloves must withstand a 5J impact with transmitted force limits. If compliant, they are marked with the letter 'P' alongside the mechanical performance pictogram.
