What is BS EN 60721-3-5:2018?

BS EN 60721-3-5:2018 is a technical standard that specifies classifications and environmental conditions for electrical equipment used in outdoor environments. This standard is particularly important for electronic devices such as sensors, amplifiers, and control systems that are exposed to various weather conditions.

The Purpose of BS EN 60721-3-5:2018

The main purpose of BS EN 60721-3-5:2018 is to provide guidance on classifying the degree of protection required for electrical equipment based on their ability to withstand different environmental conditions. This helps manufacturers ensure that their products can perform reliably and safely in outdoor settings.

Environmental Classification

The standard defines different ratings for environmental conditions. These ratings include temperature, humidity, altitude, and exposure to sunlight, rain, snow, and wind. Each rating specifies a range or limit within which the equipment should operate without suffering any damage or performance degradation.

Testing and Certification

Manufacturers are required to test their equipment in accordance with the specifications outlined in BS EN 60721-3-5:2018. Testing verifies if the equipment meets the defined environmental classification requirements. Products that pass the testing process can then be certified as compliant.

In conclusion, BS EN 60721-3-5:2018 is an important technical standard that ensures electrical equipment can withstand outdoor environmental conditions. By adhering to this standard, manufacturers can demonstrate that their products are reliable and safe for use in various outdoor settings.
