Inspection standard of plastic-coated hose

Plastic-coated hose is a more common type of hose in our lives. The hoses of the same variety, same inner diameter, and 1000 meters long are used as a batch during inspection. Randomly extract 100 meters from it for appearance inspection. The inner diameter of the sample should meet the requirements of this standard. The arithmetic average of the weight per unit length and the water seepage of the three samples shall meet the requirements of this standard, and one sample shall be subjected to only one state of blasting test, and shall meet the requirements of this standard.

When inspecting the products of micro-spray tape manufacturers, if a certain item does not meet the requirements of this standard, the item is allowed to be re-inspected once. During the re-inspection, double the sample taken in the most economical way. The results of the sample re-inspection should meet the requirements of this standard, otherwise it is a non-conforming product. The smooth quality of the hose coating is better, and the effect is better in terms of high pressure resistance and anti-aging ability. Finally, everyone should pay attention to the method of use when buying a high-quality hose, especially not to make the hose contact with high-temperature objects. .
