Foreword
IS0 (the lnternational Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates 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
iTeh STANDARD PREVIEW
Standard requires approval by at least 75 % of the member bodies casting
a vote.

(informative)
Basic specification
Initially ten test pieces should be tested. A single failure is permitted.
If two or three failures occur, it is recommended that a further 20 test pieces be tested. The total number of fail-
ures, expressed as a percentage, should not exceed IO %.
