What is BS EN ISO 10371:2014+A1:2019?

BS EN ISO 10371:2014+A1:2019 is a technical standard that provides guidelines for the determination of the gas permeability of rubber to gases. The standard is applicable to both solid and sponge products made of vulcanized or thermoplastic rubber.

The Importance of Gas Permeability Testing

Gas permeability testing plays a crucial role in various industries where rubber materials are used, such as automotive, aerospace, and manufacturing. The ability of rubber to resist the passage of gases is important for ensuring the performance and safety of products.

This technical standard establishes a standardized method for measuring the gas permeability of different types of rubber materials, including those used for seals, gaskets, hoses, and other applications where gas tightness is critical.

Key Parameters Measured

BS EN ISO 10371:2014+A1:2019 specifies two main parameters that are measured during gas permeability testing: the permeability coefficient and the solubility coefficient.

The permeability coefficient measures the ease with which a specific gas can pass through the rubber material. This parameter helps in evaluating the effectiveness of the rubber material as a barrier against gases. The lower the permeability coefficient, the better the barrier properties of the rubber.

The solubility coefficient, on the other hand, measures the amount of a gas that dissolves or is absorbed by the rubber material. This parameter is essential for understanding the interaction between the rubber material and the gas, which can affect its physical and chemical properties.

Testing Procedure

The testing procedure outlined in this standard involves conditioning the rubber samples under specific temperature and humidity conditions before subjecting them to the gas permeability test. The test apparatus consists of a chamber that holds the rubber specimen and measures the flow of gas through it.

During the test, the pressure difference and temperature are controlled to create a consistent testing environment. The diffusion cell method or the equal-pressure method can be used depending on the specific requirements. The samples are also tested using different gases to assess their permeability to various types of gases.

BS EN ISO 10371:2014+A1:2019 is an important technical standard that ensures the accuracy and reliability of gas permeability testing for rubber materials. By following this standard, industries can have confidence in the quality and performance of rubber products.
