Introduction

Analysis of the core content of the standard

GB/T 14905-2020 is a standard for the determination of interlayer adhesion strength of rubber and plastic hoses. Its technical points include:

Term definition: clarify the definition of the bonding interface (liner/reinforcement layer, outer cover/reinforcement layer, etc.)
Specimen type: applicable scenarios of 8 types of specimens (1-8 types) (different structures such as machineweaving, braidedwoven, etc.)
Test equipment: Class 0.5 or Class 1 testing machine, 50mm/min standard peeling speed

Technical evolution of the new standard

Improvements	2009 Edition	2020 Edition
Specimen type	Type 7 is only applicable to spiral line spacing>10mm	Expanded to the preparation scheme with spacing<10mm
Graphical accuracy	Figure 1-8 is ambiguous	Optimize graphical representation (Figure 1-8)
Terminology system	Not listed separately	Added Chapter 3 Definition of Terms

Implementation Guidance and Suggestions

Application Case: When selecting 4 type sample (inner diameter ≤ 20mm) in the production of hydraulic hose, please note:

Preferably use water cold cutting to avoid heat effects
Use PTFE coated support plate to maintain flat peeling
For multi-peak curves, analyze according to I S O 6 1 3 3

Precautions

The steel wire reinforcement layer needs special instructions due to the influence of dispersion
The standard appendix (Figure 1-8) needs to be used with a new set of drawings
Environmental adjustment: 16h (STP conditions)
