Building valves. Hydraulic safety groups. Tests and requirements Ingestion-build-51215What is BS EN 1487 Hydraulic safety groups about? Hydraulic safety group are safety device that limits the pressure in hot water heaters, prevents the backflow of water into the main circuit, prevents the discharged water from coming into contact with the water in the water heater, allows the function of the backflow prevention to be controlled and isolates and drains the water heater for maintenance services. BS EN 1487 is a European Standard that

The methods for determination of changes in properties are specified as follows:

BS 5866-4 is the fourth part of an international standard that focuses on blankets suitable for use in the public sector

This International Standard specifies a test method for determining the adhesion strength of the cover to the core layer

when mounted in their mounting systems

BS EN 4536-2:2009  Aerospace series

Table 2 and Table 3 is not exceeded

BS EN 61587-3 specifies the tests for empty cabinets and subracks concerning electromagnetic shielding performance
