What is ISO 2322:2014-Styrene-butadiene rubber (SBR) — Emulsion- and solution-polymerized types — Evaluation procedures?
ISO 2322:2014 specifies the evaluation procedures for styrene-butadiene rubber (SBR), both emulsion-polymerized and solution-polymerized types. SBR is a synthetic rubber that is produced by the copolymerization of styrene and butadiene. And it is commonly used in the production of tires, conveyor belts, and other rubber products.
The standard provides guidance on the testing of various physical and mechanical properties of SBR, including tensile strength, elongation at break, resilience, and abrasion resistance. It also covers the testing of chemical properties. Such as the composition of the polymer, the content of residual monomers, and the amount of gel and filler present in the material.
ISO 2322 is intended for use by manufacturers, testing laboratories, and regulatory authorities to evaluate the quality and performance of SBR. By following the evaluation procedures specified in the standard, the quality and consistency of SBR products can be assessed, ensuring that they meet the requirements of specific applications and regulatory requirements.
Requirements of ISO 2232
ISO 2322:2014 provides detailed requirements for the evaluation of styrene-butadiene rubber (SBR), both emulsion-polymerized and solution-polymerized types. The standard specifies the following evaluation procedures for SBR:
Sampling and preparation of test specimens: The standard provides guidance on the sampling and preparation of SBR test specimens. Including the number and size of specimens required for different tests.
Tensile properties: ISO 2322 specifies methods for measuring the tensile strength, elongation at break, and stress-strain behaviour of SBR.
Resilience: The standard provides procedures for measuring the resilience of SBR. Which is the ability of the material to recover its original shape after being compressed.
Abrasion resistance: The standard specifies methods for measuring the abrasion resistance of SBR. Which is its ability to resist wear and tear caused by friction.
Composition analysis: The standard provides procedures for analyzing the composition of SBR. Including the content of styrene and butadiene, as well as the content of residual monomers.
Gel content and filler content: ISO 2322 specifies methods for determining the gel content and filler content of SBR. Which are important parameters that affect the properties of the material.
ISO 2322:2014 is designed to ensure that the quality and performance of SBR are evaluated consistently and accurately, allowing manufacturers, testing laboratories. And regulatory authorities to make informed decisions about the suitability of the material for specific applications.
