3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
protective gloves against mechanical risks
gloves used to protect against at least one mechanical injury risk during wear, cutting, tearing, and puncture
3.2
glove series

4 Technical requirements
4.1 General protection requirements
The protective gloves complying with this document shall first meet the applicable requirements in GB 42298-2022. The wear resistance, tear resistance, and puncture resistance of protective gloves against mechanical risks shall meet at least the minimum requirement Grade 1 listed in Table 1, and the blade cut resistance shall meet at least the minimum requirement Grad 1 listed in Table 1 or the minimum requirement Grade A listed in Table 2.
Note: Gloves that meet puncture resistance requirements may not necessarily be suitable for preventing punctures from sharp objects, such as syringe needles or other sharp objects.
