Basis for determination
A1.1 Abrasion category
GB 11651-89
Appendix A
Determination of the service life of labor protection products
(reference)
The friction, corrosion and damage capacity of labor protection products are classified according to working conditions. See Table AI. Table A1
Abrasion categories
Heavy abrasion
Medium abrasion
Light abrasion
Wear conditions
Typical working conditions or notes
Frequent contact with rough objects, frequent rubbing, frequent dry and wet, heavy physical work (manual handling), underground excavation, high temperature, acid and alkali, chemical corrosion, drilling, easy to pollute, field, civil engineering, construction installation, forest felling and other operations, decoration machinery and equipment, packaging, general material processing, frequent contact with non-rough objects and other operations instrument monitoring, precision processing and its equipment and maintenance, assembly line operations with fixed workbenches and seats. Labor protection articles are classified according to the frequency of abrasion and wear, and the difficulty of damaging their effective protective functions, see Table A2. Table A2
Susceptible to wear
Medium wear
Mandatory scrapping
A1.3 Abrasion resistance
Gloves, masks
Work clothes, shoes
Often in full load working state, the frequency of direct abrasion is high. The working load is often not full, and the frequency of direct abrasion is not high. Safety helmets, protective glasses, masks, and respirators are generally not easy to wear during normal work, but according to the minimum index of effective protection function (excluding filters) and the requirements of effective use period, mandatory reporting is required at that time. Classification according to the durability of the materials used in labor protection products, see Table A3. Table A3
Abrasion resistance
Medium durability
Not durable
Service life
See Table A4 for the service life.
Typical conditions
Tear resistance, wear resistance, corrosion resistance, and aging resistance are poorer than the above performances
High-strength chemical fibers such as aramid, fluorine-containing fibers, phenolic fibers, polyester, woolen fabrics, leather, and canvas products
Medium-strength chemical fibers such as nylon, Dacron, vinylon, labor wool, yarn, and polyvinyl chloride products
! Polyvinyl chloride film, cotton yarn, and paper products have low fabric strength, loose structure, and are fragile. The strength decreases rapidly after washing and use
