Foreword
This standard was drafted in accordance with the rules given in GB/T 1:1-2009:
This standard replaces GB/T 6036-2001 "Determination of Low Temperature Rigidity of Vulcanized Rubber or Thermoplastic Rubber (Gimen Test)", and
Compared with GB/T 6036-2001, the main technical changes are as follows:
---Improved the accuracy requirements for temperature measuring devices (see 4:5, 3:4 in:2001 edition);
---Modified the time requirements of the measurement interval in the case of continuous heating (see 7:2, 7:3, and 5:3, 5:4 of the:2001 edition);
---Added the principle (see Chapter 3);
---Added calibration specifications (see Appendix A):
This standard uses the translation method equivalent to ISO 1432:2013 "Determination of Low-temperature Rigidity of Vulcanized Rubber or Thermoplastic Rubber (Gimman Test)

The user is responsible for taking appropriate safety and health measures and ensuring compliance with the conditions stipulated by relevant national laws and regulations:
Note: Some steps specified in this standard may involve the use or generation of certain wastes, which may cause harm to the local environment: Related
The document shall stipulate appropriate safe operation and waste disposal after use:
1 Scope
This standard specifies the determination of the relative stiffness of vulcanized rubber or thermoplastic rubber in the static process from room temperature to -150°C:
The method of sexual characteristics is also called the Gimen test:
2 Normative references
The following documents are indispensable for the application of this document: For dated reference documents, only the dated version applies to this article
Pieces: For undated references, the latest version (including all amendments) applies to this document:
GB/T 25269-2010 Rubber test equipment calibration guide (ISO 18899:2004, IDT)
ISO 23529 Rubber-General procedures for the preparation and adjustment of rubber physical test methods (Rubber-General proceduresforpre-
paringandconditioningtestpiecesforphysicaltestmethods)
3 Principle
Starting from low temperature, the torsional stiffness is measured as a function of temperature: The rigidity measurement method is to combine the sample with the calibrated spring wire
When connecting, when twisting the top of the steel wire 180°, measure the twisting angle of the sample:
4 Test equipment
4:1 Torsion device
As shown in Figure 1, it is composed of a twisting head that can twist 180° in a plane perpendicular to the twisted steel wire: The top of the wire is fixed to
Turn on the head: The bottom of the steel wire is connected to the sample holder: An electrical or mechanical method should be provided to display or record the angle "without friction"
The high-speed device can adjust the zero point conveniently and accurately: The display or recording system should be able to read or record the twist angle to the nearest degree:
4:2 Torsion wire
The steel wire is made of tempered spring steel wire, and its length is 65mm±8mm: The torsion constant of the steel wire is 0:7mN·m,
2:8mN·m and 11:2mN·m: In case of dispute, a steel wire with a torsion constant of 2:8mN·m should be used:
4:3 Sample holder
The frame is made of material with poor thermal conductivity and is used to fix the sample vertically in the heat transfer medium: The structure of the sample holder can hold multiple test
