What is BS EN 4550-3:2017?

BS EN 4550-3:2017 is a technical standard that specifies the requirements for testing and evaluating the performance of protective clothing against chemicals. It focuses specifically on the resistance of materials used in protective clothing to permeation by liquid or gaseous chemicals.

The Importance of BS EN 4550-3:2017

In industries where workers are exposed to hazardous chemicals, protective clothing plays a crucial role in ensuring their safety. The BS EN 4550-3:2017 standard provides a reliable framework for assessing the effectiveness of such clothing in protecting against chemical hazards.

By setting guidelines for testing and evaluation, this standard helps manufacturers ensure that their products meet the necessary safety requirements. It also allows employers to choose appropriate protective clothing that meets the needs of their workers and the specific chemicals they are exposed to.

Testing Methods and Performance Criteria

The BS EN 4550-3:2017 standard outlines various Testing Methods and Performance Criteria for evaluating the protective properties of clothing. These methods include measuring the duration of time it takes for a chemical to permeate through the material, as well as assessing its breakthrough time, degradation, and penetration resistance.

Performance criteria are based on factors such as the chemical being tested, the type of material being used, and the intended use of the protective clothing. The standard provides detailed instructions on how to conduct these tests and interpret the results accurately.

Compliance and Certification

In order to meet the requirements of BS EN 4550-3:2017, manufacturers must ensure that their protective clothing complies with the specified testing methods and performance criteria. Compliance can be indicated through certification from accredited testing laboratories.

Companies purchasing protective clothing should look for products that carry the appropriate certification, as this guarantees that the clothing has undergone rigorous testing and met the necessary standards. It is essential for employers to provide their workers with certified protective clothing to ensure their safety on the job.
