Anti-static shoes main indicators and instructions for use
The anti-static product quality index refers to the quality standard that should be achieved by various products produced by the enterprise during the planning period. The anti-static product quality index is one of the main contents of the production plan indicators, and is one of the important indicators to measure the economic status and technological development level of the enterprise. Therefore, it is undoubtedly the main learning part of everyone's cognitive anti-static shoes. Now the anti-static information network will explain the main indicators and instructions for anti-static shoes.
Anti-static shoes main indicators:
1 Baotou impact resistance
The impact test shall be carried out with a steel impact hammer of a specified weight. The height of the gap under the toe cap shall be less than the specified value when the toe cap is impacted, and the piercing shall not show any penetrating cracks in the direction of the test axis. It is worth noting that the national standards have different regulations on the weight, specifications, impact height and construction of the test machine. The actual test should be distinguished.
2 anti-piercing performance
The test machine is equipped with a pressure plate on which the test nail is mounted. The test nail is a tip with a cut-off tip, and the hardness of the nail head should be greater than 60HRC. The sole sample is placed on the chassis of the testing machine in such a position that the test nail can be pierced through the outsole, and the test nail pierces the sole at a speed of 10 mm/min ± 3 mm/min until the penetration is completed. The greatest strength. Four points are selected on each sole for testing (at least one of which is at the heel), each point is not less than 30 mm apart, and the distance from the inner bottom edge is greater than 10 mm. The bottom of the anti-slip block should be pierced between the blocks. Two of the four points should be tested within 10-15 mm of the edge line of the bottom of the plant.
3 Electrical properties of conductive shoes and anti-static shoes
After the shoe sample is adjusted in a dry and wet atmosphere, the clean steel ball is filled into the human shoe and placed on the metal probe device, and the first two probes and the third probe are measured using a prescribed resistance tester. Resistance between. Under normal circumstances, conductive shoes require resistance should not be greater than l00K ohms; anti-static shoes require resistance should be between 100K ohms and 100M ohms.
4 requirements for non-slip outsole
This standard stipulates the anti-skid coefficient of the anti-static work sole, but specifies the design and specifications of the anti-slip block, such as the thickness of the sole, the height of the non-slip block, and the distance from the edge of the sole.
Anti-static shoes instructions:
1. The place where anti-static shoes are used should be anti-static ground. The place where conductive shoes are used should be ground that can conduct electricity.
2, anti-static shoes should be used with anti-static clothing, pay attention to the product's clean, waterproof, moisture-proof.
3. Anti-static shoes are protective shoes that eliminate the accumulation of static electricity in the human body and prevent electric shocks of currents below 250v.
4, anti-static shoes should not wear insulated wool thick socks and insulated insoles when wearing, prohibit anti-static shoes when used as insulated shoes
