For the purposes of this International Standard the following definitions apply.
yield stress
value corresponding to the 0,2 % proof stress, Rp 0,2
quenching

tempering
Evaluation of conformity is required to be performed in accordance with the relevant regulations of the country (ies) where the tubes are to be used. In order to ensure that tubes are in compliance with this International Standard they shall be subject to inspection in accordance with clauses 9 and 10 by an authorized inspection body (hereafter referred to as “the inspector ”) recognized in the countries of use.
