2 Normative references

The contents of the following documents, through normative references within the text, constitute essential provisions of this document. Dated citations are not included. For references to documents, only the version corresponding to that date applies to this document; for undated references, the latest version (including all amendments) applies. This document. GB/T 3922-2013 Textiles - Tests for color fastness - Color fastness to perspiration GB/T 12903 Terminology for Personal Protective Equipment GB/T 16825.1 Inspection and calibration of static uniaxial testing machines for metallic materials – Part 1.Measurement of tensile and/or compressive stresses by these machines Inspection and calibration of force systems GB 21148 Foot Protection Safety Footwear 3.Terms and Definitions The terms and definitions defined in GB/T 12903 and GB 21148, as well as the following terms and definitions, apply to this document. 3.1 Footwear components that are placed within the sole assembly (or close to the sole surface) to provide protection against mechanical penetration. 3.2 tent effect During testing, the puncture-resistant pad exhibited interlayer separation. Some layers were penetrated while others remained intact, creating a tent-like effect. An arched shape. 4.Classification 4.1 According to the material, puncture-resistant pads are divided into metal puncture-resistant pads and non-metal puncture-resistant pads. 4.2 According to the type of protection risk, non-metallic puncture-resistant pads are divided into PL type and PS type. Note. When facing smaller diameter and sharper objects, the PS type provides more appropriate protection than the PL type. 5 Technical Requirements 5.1 General Requirements 5.1.1 When no error is specified in this document (text or images), the maximum error of ±10% shall be used. 5.1.2 The performance requirements and test sample quantity for puncture-resistant pads are listed in Table 1. Note. This document applies to shoe components, not finished shoes. When selecting puncture-resistant insoles based on the test reports provided in this document, finished shoe manufacturers should ensure proper shoe sizing. The suitability and conformity with the overall performance requirements of the shoe are important reference factors. Table 1 Performance requirements and number of test samples for puncture-resistant pads Performance Requirements, Clause Number, Metal Puncture-Resistant Pads, Non-Metal Puncture-Resistant Pads, Number of Test Samples Size requirement 5.2 ● ● 1 pair Puncture resistance 5.3 ● ● 1 pair Flexural strength 5.4 ● ● 1 pair Corrosion resistance of metal puncture-resistant pads 5.5.1 ● 1 pair Stability of non-metallic puncture-resistant pads 5.5.2 ● 1 pair per treatment Note. "●" indicates the required performance; no "●" indicates that it is not applicable. 5.2 Dimensions 5.2.1 Each metal puncture-resistant pad is permitted to have a maximum of 3 mounting holes, and the diameter of each hole should not exceed 3 mm. (From the puncture-resistant pad...) Starting from the very front end, there should be no holes in the area spanning 10% to 52% of its total length (see the shaded area in Figure 1). Index number explanation. L---Full length of the metal puncture-resistant pad. Figure 1.Mounting hole location for metal puncture-resistant pads (example) 5.2.2 Non-metallic puncture-resistant pads should not have holes. 5.3 Puncture resistance 5.3.1 Puncture resistance of metal puncture-resistant pads After testing according to the method specified in 6.2.2.1, the penetration force should not be less than 1100N. 5.3.2 Puncture resistance of non-metallic puncture-resistant pads After testing according to the methods specified in 6.2.2.2 and 6.2.2.3, the test results should meet the requirements of Table 2. ......
