This document applies to protectors designed to protect the eyes and face of personnel engaged in welding and related operations from harmful factors such as optical radiation, hot particles, molten droplets, and molten metal splashes. 2 Normative references The following documents contain provisions which, through reference in this text, constitute essential requirements for this document. For dated references, only the editions cited apply. For undated references, the latest edition (including any amendments) applies. GB/T 30042—2013 Personal protective equipment for eyes and face—Terminology GB/T 32166.2—2015 Personal protective equipment for eyes and face—Occupational eye and face protectors—Part 2: Measurement methods 3 Terms and definitions Terms and definitions established in GB/T 30042—2013 and the following apply to this document. 3.1 Welding protector Protective equipment designed to protect the wearer from harmful optical radiation and other hazards during welding or related operations. Note: Includes but not limited to welding helmets, welding goggles, and welding spectacles. [Source: GB/T 30042—2013, 5.4.1, modified] 3.2 Welding face-shield Face-shield equipped with filter lenses to protect the wearer's eyes and face during welding or related operations. [Source: GB/T 30042—2013, 5.4.3, modified] 3.3 Welding goggle Protective equipment typically secured by headbands, covering the eyes and surrounding areas, designed to protect against optical radiation generated during welding and related operations. [Source: GB/T 30042—2013, 5.4.2, modified] 3.4 Welding spectacles Spectacles with side protection that position appropriate filter lenses in front of the eyes to protect against optical radiation generated during welding and related operations. [Source: GB/T 30042—2013, 5.4.5, modified] 3.5 Filter Lens that attenuates radiation at specific wavelengths to prevent excessive optical radiation from entering the eyes. [Source: GB/T 30042—2013, 9.1.1, modified] 3.6 Shade number Numerical designation indicating the darkness or visible light transmittance attenuation level of a filter lens. [Source: GB/T 30042—2013, 9.1.5] 3.7 Protective plate Lens typically placed in front of and/or behind the filter lens, designed to protect against hot particles, molten droplets, molten metal splashes, and scratches. [Source: GB/T 30042—2013, 5.5.3, modified] 3.8 Automatic welding filter Filter lens that can quickly change the shade number from a lower value (light state shade number) to a higher value (dark state shade number) when welding arc is generated, and maintain the dark state when arc is present. Note: Automatic welding filter is also known as automatic welding filter lens. [Source: GB/T 30042—2013, 9.3.2, modified] 3.9 Welding filter for side view Filter lens installed around welding helmets or face-shields for welders to observe the surrounding environment (not for direct viewing of welding arc). 3.10 Welding filter for direct view Filter lens installed on the front of welding helmets or face-shields. 4 Classification 4.1 Welding protectors Welding protectors are classified into welding face-shields, welding goggles, and welding spectacles based on their structural design. 4.2 Filter lenses Filter lenses are classified into fixed shade number filter lenses and automatic welding filters based on their working principles. Note: Automatic welding filters are specified in GB 3609.2. Based on functional purposes, filter lenses are classified into welding filters for direct view and welding filters for side view. 5 Technical requirements 5.1 Materials 5.1.1 Welding spectacles, goggles, and face-shields 5.1.1.1 The surfaces of welding spectacles and goggles should be smooth and free from burrs, sharp edges, or any defects that may cause discomfort to the eyes and face. Visual inspection and touch methods should be used for product testing. 5.1.1.2 Welding spectacles, goggles, and face-shields should meet the requirements of their intended purpose and operating environment, and should not contain any factors that may affect the health or safety of the wearer. Manufacturers should declare that material exudation will not cause skin irritation to the wearer. Manufacturers may confirm material safety by obtaining test reports from material suppliers. 5.1.1.3 The headbands of welding goggles should be made of soft materials. 5.1.1.4 Except for filter lenses, face-shields should be made of opaque materials with sufficient strength. The surfaces should be smooth and free from delamination, bubbles, and transparent defects. Visual inspection methods should be used for testing. 5.1.2 Protective plates and filter lenses According to the test method specified in GB/T 32166.2—2015, section 5.6, except for a 5 mm wide area around the edges, protective plates and filter lenses should be smooth, uniformly colored, and free from scratches, streaks, bubbles, foreign objects, or any other defects that may impair optical performance. 5.2 Structure Welding spectacles, welding goggles, and welding face-shields should meet the following structural requirements: a) Adjustable parts should be flexible and reliable, and components should be securely fitted. Any metal parts should not come into contact with the face or head; b) Welding goggles should have good ventilation. If ventilation holes are provided, they should be indirect ventilation holes; c) Any part of the welding protector that can be adjusted or removed by the wearer for replacement (according to the instructions provided by the manufacturer) should be easily adjustable, removable, and tightened without the use of tools; d) The tilting mechanism of head-mounted face-shields should be flexible and reliable, and the headband should be adjustable. 5.3 Specifications 5.3.1 Welding face-shields Welding face-shields are classified into hand-held welding face-shields [see Figure 1(a)], head-mounted welding face-shields [see Figure 1(b)], and safety helmet-combined welding face-shields [see Figure 1(c)] based on their structural design. After fully loosening the headband or headband and adjusting the width to the maximum size, the specifications of welding face-shields should meet the following requirements: a) Length: Hand-held and head-mounted types should not be less than 310 mm, safety helmet-combined type should not be less than 230 mm; b) Width: Should not be less than 210 mm;
