Four specimens are cut according to the requirements of Article 6.2.1, and three specimens are cut according to the requirements of Article 6.2.2. They are placed in an air thermostat at a temperature of 70℃±2℃ and a relative flow rate of less than 20% for 168 hours. In the air thermostat, there must be an air circulation of 3 to 10 times per hour. The temperature of the input air, that is, the temperature of the air in contact with the specimen, should be 70±2. There should be no steel or alloy parts in the air thermostat, and there should be a device for suspending the specimens. There should be at least 10mm between the specimens, and at least 50mm between the specimens and the inner surface of the thermostat. After heating, the specimens are taken out of the thermostat and the cooling time should be no less than 16 hours. Then, the four specimens are subjected to tensile strength and elongation at break tests according to the provisions of Article 6.2.1, and the other three specimens are subjected to tensile permanent deformation tests according to the provisions of Article 6.2.2. 6.4 Flame resistance test
For type test and sampling test, a flame resistance test shall be carried out. As shown in Figure 4, cut a sample of 60mm to 70mm in length from the second or third finger of the insulating glove, and mark the reference line 55mm from the end. Fill the inside of the finger with stone and install it on a steel rod with a diameter of 5mm and a length of 120mm. The steel sample should be centered on the center axis of the finger, and the plaster should be hardened for 24 hours. Place the burning nozzle vertically below the sample, with the nozzle axis 5mm away from the end of the sample, and the nozzle diameter is 9.5m ± 0.5mm. A blue flame with a height of 20mm ± 2mm can be generated. The flame is withdrawn after heating the sample for 10 minutes. The heating should be carried out in a test room without wind or air flow.
6.5 Low temperature resistance test
For type test and sampling test, a low temperature resistance test is carried out. The finished gloves and the vinyl plate are placed in a cold place at F-25°C for 1 hour.Within 1 minute after taking out the gloves at room humidity of 23℃±2℃, apply force for 30s at the wrist of the gloves according to Figure 5. 7 Process finishing and appearance inspection
Appearance inspection and thickness inspection shall be carried out for type test, routine test and sampling test. 7.1 The surface of gloves must be smooth, and there shall be no obvious defects such as pinholes, spots, cracks, sand holes, impurities, trimming marks, clamping marks, obvious ripples and obvious mold marks on the inside and outside. No traces of dye stains are allowed. When small depressions, ridges or indentations appear on the surface of gloves, they shall not be considered as quality products if the following requirements are met. a) The diameter of the depression shall not exceed 1.6mm, and there shall be no obvious cracks on the arc-shaped edge and its surface. No traces can be seen when the thumb is spread on the reverse side. There shall be no more than three depressions and the distance between two depressions shall not be less than 15mm; b) There shall be no such defects on the palm and fork of the hand; c) Small ridges are only small pieces of raised rubber, which are not easy to remove with fingers and do not affect the elasticity of the rubber. The palm and finger surfaces designed to improve the grip effect should not have defects. 7.2 Appearance inspection is mainly based on visual inspection, and the degree of defects is determined by measuring. The length is measured with a steel ruler with an accuracy of 1 m, and the thickness is measured with a vernier caliper with an accuracy of 0.02 mm.
