EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of GB/T 2951-21 testing. GB/T 2951.21 is a Chinese standard for common test methods for insulation and coating materials of electrical and optical cables, especially for elastomeric compounds. Part 21 of this standard specifies methods for testing these materials for their ozone resistance, hot set and mineral oil immersion properties.
Ozone resistance is an important property of elastomeric compounds because exposure to ozone can cause cracking and other types of damage that can affect the overall performance and safety of cables. The GB/T 2951.21 standard provides a standardized method for testing the ozone resistance of these materials.
Hot set is another important property of elastomeric compounds as it measures the material's ability to retain its shape and properties under high temperature and stress conditions. The standard provides a method for testing the hot curing properties of these materials.
The mineral oil immersion test, which evaluates the resistance of elastomeric compounds against mineral oil, is also included in the standard. This is important for applications where cables may be exposed to mineral oil, such as power transmission.
The GB/T 2951.21 standard provides detailed procedures for performing these tests, including the equipment required and the conditions under which the tests must be performed. It also provides guidance on how to report and interpret the results of these tests.
Overall, the GB/T 2951.21 standard provides a standard and reliable method for testing the ozone resistance, hot set and mineral oil immersion properties of elastomeric compounds used in electrical and optical cables, helping to ensure their safe and effective use in a range of cables.
