What is BS EN 437 about?
BS EN 437 discusses gases, pressures, and appliance categories. BS EN 437 specifies the test gases, test pressures, and categories of appliances relative to the use of gaseous fuels of the first, second, and third families.
BS EN 437 serves as a reference document in the specific standards for appliances that fall within the scope of the Council Directive on the approximation of the laws of Member States concerning gas appliances 2009/142/EC.
Note: The test gases and the test pressures specified in BS EN 437 are in principle intended to be used with all the appliances to establish conformity with the corresponding standards.
The use of some test gases and test pressures may not be appropriate in the following cases
- Appliances with nominal heat input greater than 300 kW
- Appliances constructed on site
- Appliances in which the final design is influenced by the user
- Appliances constructed for use with high supply pressures (notably direct use of the saturated vapor pressure).
Who is BS EN 437 for?
BS EN 437 on Test gases – Test pressures – Appliance categories is applicable to:
- Crude Oil refineries
- Coal Manufacturer
Why should you use BS EN 437?
The concern for clarity has led to the explanation of numerous categories. BS EN 437 seeks to clarify the present situation with respect to test gases, test pressures, and appliance categories.
BS EN 437 is considered as an important stage in the harmonization of test gases, test pressures and appliance categories, and the quality of information on gas usage.
BS EN 437 provides you with recommendations for the use of the gases and pressures to be applied for the tests.
