What is EN ISO 20340:2017?

EN ISO 20340:2017 is a standard that specifies the requirements and test methods for protective clothing, specifically designed to protect against rain and foul weather conditions. This technical article aims to provide a comprehensive understanding of EN ISO 20340:2017 and its significance.

Scope and Background

The scope of EN ISO 20340:2017 covers protective clothing that offers protection against precipitation such as rain or snow, as well as wind, in combination with low temperatures. It applies to clothing used in various professional activities, including construction, agriculture, utilities, and outdoor sports. The standard ensures that the clothing provides effective protection while maintaining comfort and ease of movement for the wearer.

Key Requirements

EN ISO 20340:2017 sets forth specific requirements regarding the materials, design, and construction of protective clothing. It establishes criteria for water resistance, breathability, and durability. The clothing should be able to withstand prolonged exposure to rain and maintain its protective properties over time. Additionally, it should facilitate efficient moisture transfer to prevent the build-up of condensation on the inner surface.

Testing and Certification

In order to comply with EN ISO 20340:2017, manufacturers must subject their protective clothing to rigorous testing procedures. These tests evaluate the clothing's ability to resist water penetration, measure its breathability, and assess its overall performance in wet conditions. Proper certification ensures that the clothing meets the necessary standards and can be relied upon for adequate protection.

Overall, EN ISO 20340:2017 seeks to enhance the quality and effectiveness of protective clothing for use in rain and foul weather. By adhering to this standard, both manufacturers and users can have confidence in the performance and reliability of these essential garments.
