Sets out test procedures and criteria for the determination of fire-resistance of elements of building construction. Follows the basic principles and provisions contained in ISO 834:1975.
Scope
This Standard applies to heating conditions, test procedures, and criteria for the determination of fire-resistance of an element of building construction. In most cases, a single test, carried out in accordance with this Standard, establishes the fire-resistance for the element of construction concerned.
In addition to providing information on which the fire-resistance of an element of construction can be assessed, the test report includes information which may be of use to the designer. (Records of temperature at critical times may be used by a designer to assess the fire-resistance of a variant of the tested prototype flexural member where the procedure for such an assessment is defined in the appropriate design code.) In certain cases, the test methods described herein provide information for the determination of-
(a) resistance to the incipient spread of fire through ceiling systems;
(b) safe distances for the spacing of combustible materials from elements that provide a separating function;
(c) radiant heat flux emitted from doorsets, shutter assemblies, damper assemblies and glazing; and
(d) the free cross-sectional area of air ducts to provide functional operation while providing fire-resistance.
