What is BS EN 60721-2-3 - Selection of values of air pressure about?
BS EN 60721-2-3 is a standard that covers the selection of values of air pressure, enabling stable operability and consistency of products in changing air pressure conditions.
BS EN 60721-2-3 presents a selection of different values of air pressure appearing in nature.
BS EN 60721-2-3 is intended to be used as part of the background material when selecting appropriate severities of air pressure for product applications, which products are liable to be exposed during storage, transportation and use.
Who is BS EN 60721-2-3 - Selection of values of air pressure for?
BS EN 60721-2-3 on the selection of values of air pressure applies to:
- Quality assurance services
- Safety assurance services
- Environment testing laboratories
- Simulation testing services
- Product developers and designers
Why should you use BS EN 60721-2-3 - Selection of values of air pressure?
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 60721-2-3 provides users guidance on air pressure effects including, air pressure lower than normal, air pressure higher than normal, and values of air pressure, enabling users to prevent product failure and ensure product consistency.
With obedience and compliance to BS EN 60721-2-3, users can assess product resistance to changing atmospheric conditions, ensuring their quality and longevity.
What’s changed since the last update?
BS EN 60721-2-3:2014 supersedes BS 7527-2.3:1991, which is now withdrawn.
Changes in BS EN 60721-2-3:2014 include:
- Removal of figures for decreasing cooling efficiency for altitude
- Simplification of Table 1
- Additional formula for calculating air pressure from altitude
