Bibliography

Describes requirements for the construction and performance of sprinklers which are operated by a change of state of an element or bursting of a glass bulb under the influence of heat, for use in residential and domestic automatic sprinkler systems.

This British Standard specifies requirements for the construction and performance of sprinklers which are operated by a change of state of an element or bursting of a glass bulb under the influence of heat, for use in residential and domestic automatic sprinkler systems conforming to BS9251. Test methods and a recommended test schedule for type approval testing are also given.

NOTE All pressure data in this standard are given as gauge pressures in bar¹⁾.
