Fire resistance tests - General requirements1 Scope This document establishes the general principles for determining the fire resistance of various elements of construction when subjected to standard fire exposure conditions. Alternative and additional procedures to meet special requirements are given in EN 13632. The principle that has been embodied within all European standards relating to fire resistance testing is that where aspects and procedures of testing are common to all specific test

ISO 6621‑2 specifies the general measuring conditions of piston rings for inspection of engines along with the characteristics and measuring principles in accordance with ring width

Once significant fire scenarios have been identified

There is no requirement for excavation so the surrounding road surface is not damaged

Guidelines for the application of the specified methods over an extended frequency range in respect to lower frequencies are given in Annex E
