Rubber and plastic hose and hose assembly terminology1 ScopeThis standard defines the terms and definitions for rubber and plastic hose and hose assemblies. This standard applies to the hose industry. This standard is divided into two units. 2.1 hose terminology; 2.2 Hose assembly terminology. Note 1. The following hose terms also apply to hose assemblies. bending radius, bending, bending force, burst pressure, elongation, hydrostatic stability, hydrostatic stability Test, pulse test, bend, maximum working pressure, minimum bend radius, verification pressure, verification pressure test, crimp diameter, test pressure, vacuum resistance Energy, vacuum stability, vacuum test, working pressure, working temperature. Recommended conductivity terms and resistance ranges are given in Appendix A of GB/T 9572-2013.2 Terms and definitions2.1 Hose Terms 2.1.1 Adhesion strength adhesion Bonding strength between vulcanized rubber surfaces or between vulcanized rubber surface and non-rubber surface, or two non-rubber (plastic) hose layers Bond strength between welded or glued together. 2.1.2 Braided angle angleofbraid Wiring angle angleoflay An acute angle is formed between any of the braided strands in the braid and a line parallel to the axis of the hose. 2.1.3 Antistatic wire anti-staticwire Electrical connection wire bondingwire Wire conductingwire Connected to the inside of the hose wall (2.1.60) to release static electricity generated in the hose, usually connected to the joint connector (2.2.10) A metal wire often made of fine copper wire. 2.1.4 Armored hose armouredhose Hose with outer protective layer (2.1.58), the protective layer is generally a layer of braid (2.1.17) or spiral (2.1.54) to minimize Damage. 2.1.5 Armoring layer armouring The outer protective layer on the outside of the hose to prevent mechanical damage or support the hose reinforcement, typically a braid (2.1.17) or spiral ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 7528-2025_English be delivered?Answer: Upon your order, we will start to translate GB/T 7528-2025_English as soon as possible, and keep you informed of the progress.
