Foreword
2007 "Determination of vulcanized rubber or thermoplastic rubber and rigid plate shear modulus and adhesion strength. ISO 1827 equivalent standards adopted
Four plate shear method "(in English).
This standard replaces GB/T 12830-1991 "vulcanized rubber and metal bonding shear strength determination of four plate method."
This standard is equivalent translation ISO 1827.2007.
For ease of use, this standard made the following editorial changes.
a) 'this International Standard' to replace the word 'this standard';
b) Remove the preface international standards;
c) In Chapter 11 units N/mm2 unity expressed in MPa;
d) adding a provision in the note section 6.1 of this standard.
This standard compared with GB/T 12830-1991 main changes are as follows.
--- Changing the name of the standard;
Determination of the object --- expanded from vulcanized rubber vulcanized rubber, thermoplastic rubber;
--- Increasing the shear modulus measurement method (Excerpts 3.1,4.1,10.1,11.1,12.1);
--- Use text instead of the original δsh showing adhesive strength, deleting the original S = 1 × 10-3m2 values \u200b\u200b(1991 version 8.1; edition
11.2.1).
The standard proposed by China Petroleum and Chemical Industry Association.
This standard by the National Standards Commission rubber rubber physical and chemical test methods for Standardization Technical Committee (SAC/TC35/SC2) centralized.
This standard was drafted. Shanghai Rubber Products Research Institute, Beijing Rubber Industry Research and Design Institute.
The main drafters of this standard. Li Xian right, Yang Chenyun, Xiejun Fang.
This standard replaces the standards previously issued as follows.

Warning --- personnel should use this standard regular laboratory work experience. This standard does not point out all possible security asked
Questions, the user has the responsibility to take appropriate safety and health practices and to ensure compliance with the conditions relevant national regulations.
Some Notes on operation --- covered by this standard may be used to generate some substance or waste generation and pollution of the local environment
Impact, should develop appropriate document disposal after use of these substances.
1 Scope
This standard specifies the determination between the four parallel rigid plates bonded rubber shear modulus and rubber and metal or other rigid board adhesive
Test methods for strength.
A method for the determination of shear modulus of the rubber.
Method B for the determination of rubber adhesion strength.
This method is applicable to samples under standard laboratory conditions of preparation, the test results may also be a rubber material and the adhesive member cut production
Research and control method for providing test data.

3 Terms
The following terms and definitions apply to this standard.
3.1
The total shear stress divided by the shear stress direction according to standard methods specified in the rubber part of the bonding area of \u200b\u200bthe specimen calculated on
strain.
Note 1. The shear strain (γ) is a half divided by a rubber sheet that is monolithic plate thickness deformation measurements.
Shear stress (τ) is the value of the applied force divided by a rubber sheet that is double the value of the single board adhesive area.
Note 2. The specimen shall be prepared to ensure that the adhesive surface of the normal stress is zero, so that deformation can be considered pure shear deformation state.
Note 3. The standard definition of the shear modulus is sometimes called the secant modulus.
Principle 4
4.1 Method A Determination of shear modulus
Principle of the method is the determination to make the standard sample size to achieve a predetermined force required to shear deformation value. Such samples from the four rubber sheet
Symmetrical parallel plates and adhered to the four components. Maximum force parallel to the bonding face, and usually does not destroy the sample, the force
