Introduction

1. Background and significance of the standard

GB/T39693.7-2022/ISO487:2018 "Determination of hardness of vulcanized rubber or thermoplastic rubber Part 7: Determination of apparent hardness of rubber rollers by Shore hardness method" is based on the international standard ISO487:2018 and is intended to standardize the measurement method of the surface hardness of rubber rollers in the rubber products industry.

This standard fills the gap in the determination of apparent hardness of rubber rollers in the domestic rubber products field and provides the industry with a set of scientific and unified testing methods.

2. Comparative analysis of standard frameworks

Standard dimensions	GB/T39693.7-2022/ISO487:2018	ISO487:2018	Comparative analysis
Scope of application	Determination of apparent hardness of vulcanized rubber or thermoplastic rubber coated rollers	Determination of hardness of vulcanized rubber or thermoplastic rubber-Part 7	Completely consistent
Measurement method	Shore A and D durometers	Shore durometer method	Detailed requirements for rubber roller surface measurement
Accuracy requirements	Medium accuracy	General hardness test	Targeted enhancement

3. Implementation suggestions and precautions

3.1 Laboratory condition requirements

Standard laboratory temperature control (see ISO23529)
Equipment calibration procedures are performed regularly
Professional training for operators

3.2 Selection of measuring instruments

Shore A hardness tester is suitable for medium hardness range, and Shore D hardness tester is used for high hardness testing.

3.3 Data Recording and Analysis

It is recommended to take the median of three measurements as the result
Record the test environment conditions in detail
Establish a data traceability mechanism
