BS EN 60721-2-1:2014

What is BS EN 60721-2-1 - Classifications of open-air climates about? 

BS EN 60721-2-1 is a standard that covers the classifications of open-air climates, ensuring the product’s quality, durability and reliability in different climatic conditions. 

BS EN 60721-2-1 presents classifications of open-air climates in terms of temperature and humidity. BS EN 60721-2-1 is intended to be used as part of the background material when selecting appropriate temperature and humidity severities for product testing and application. 

BS EN 60721-2-1 covers climates around all areas of the world, excluding the central Antarctic and high altitudes (above 5 000 m). 

BS EN 60721-2-1 may be used as background material when issuing climatic environmental classes for product applications. 

BS EN 60721-2-1 defines a limited number of open-air climate classifications, in terms of temperature and humidity, which represent the conditions most frequently met by-products while being transported, stored, installed and used. 

Who is BS EN 60721-2-1 - Classifications of open-air climates for? 

BS EN 60721-2-1 on the classifications of open-air climates applies to: 

• Quality assurance services 
• Safety assurance services 
• Environment testing laboratories 
• Simulation testing services 
• Product developers and designers 

Why should you use BS EN 60721-2-1 - Classifications of open-air climates? 

Electrotechnical products are used in almost all areas of the world under varying climatic conditions and have to meet the stresses imposed by these climatic conditions with the necessary reliability. Detailed knowledge of the climatic conditions to which the product will be subjected is necessary for the design stage to ensure that reliability is met. 

BS EN 60721-2-1 provides users guidance on open-air climates, including environmental parameters, identification of statistical open-air climates, and map of open-air climates, enabling users to monitor and assess the impact of different climatic conditions on their products. 

BS EN 60721-2-1 provides users guidance on general information regarding data collection and analysis, general validation process, open-air climates and climate classifications, enabling users to design products that can withstand the changes in climatic conditions. 

With obedience and compliance to BS EN 60721-2-1, users can assess different climates such as tropical, arid, temperature, cold, polar and their impact on product integrity, design and development. 

What’s changed since the last update? 

BS EN 60721-2-1:2014 supersedes BS 7527-2.1:1991, which is now withdrawn.
