of preparing International Standards is normally carried out through ISO
technical committees. Esch member body interesred in a subject f:3r

and non-governmental, in liaison with ISO, aiso take part in the work. ISO
coilaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International

Introduction
In the i95Os and 1960s when this International Standard was first pre-
pared, three types of tensile tester were in wide use: constant rate of
specimen extension (CRE), constant rate of travel (CRT), and constant rate
of loading (CRL). lt was therefore advisable to state the rate of Operation
in a way which would be common to all three types of tester. In addition,
the best possible agreement was sought between test results of the three
types of tester. Consequently, the principle of constant time to break was
adopted and 20s to break was Chosen for this International Standard and
also for a number of national Standards.
In the early 1990s when the present revision was prepared, CRE testers
were recognized as the best type, while CRT and CRL testers were quickly
becoming obsolete. However, since CRT and CRL testers are still in use
internationally, the procedure for using them is included in an informative
annex. There is no assurance that the results from the three types of
tester will agree.
This International Standard considers CRE testers only, so the time-to-
break principle is no longer needed and a simpler Statement of rate of
displacement is used. The rate of extension of 100 % per minute is
adopted as Standard, but higher rates are permitted by agreement for
automatic testers.
