What is EN ISO 23937:2021?

EN ISO 23937:2021 is a technical standard that specifies the requirements for textile fabrics intended to be used in protective clothing against gaseous and liquid chemicals.

The Purpose of EN ISO 23937:2021

The main purpose of EN ISO 23937:2021 is to ensure that the textile fabrics used in protective clothing provide a sufficient level of protection against potential hazards posed by chemical substances. This standard sets out specific requirements for fabric performance, including resistance to penetration and permeation by chemicals.

Fabric Performance Requirements

The fabric used in protective clothing must meet certain performance requirements outlined in EN ISO 23937:2021. These requirements include resistance to penetration and permeation by various types of chemicals. The standard defines test methods and procedures to evaluate the fabric's ability to withstand exposure to chemicals.

The resistance to penetration refers to the fabric's ability to prevent the passage of liquids through its surface. The resistance to permeation, on the other hand, refers to the fabric's ability to resist the passage of chemicals through its structure over time.

Additional Considerations

In addition to performance requirements, EN ISO 23937:2021 also addresses other aspects related to protective clothing. These include constructional requirements, such as seams and closures, as well as labeling and information provided with the garments.

The standard provides guidelines for manufacturers, regulatory bodies, and users to ensure that protective clothing meets the necessary safety standards. Compliance with EN ISO 23937:2021 helps to ensure that workers are adequately protected when working in environments where exposure to chemical hazards is a concern.

Overall, EN ISO 23937:2021 plays a crucial role in ensuring the safety and effectiveness of protective clothing intended to protect against chemical hazards. By establishing specific performance requirements and test methods, this standard helps to provide confidence in the performance of textile fabrics used in such garments.
