Foreword
IS0 (the International 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
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 6251 was prepared by Technical Committee
ISO/TC 28, Petroleum products and lubricants.
IS0 6251: 1982
This second edition ca ncels and replaces the first edition

Liquefied petroleum gases - Corrosiveness to copper -
Copper strip test
WARNING - The use of this International Standard may involve hazardous materials, operations and
equipment. This standard does not purport to address all of the safety problems associated with its use. It
is the responsibility of the user of this International Standard to establish appropriate safety and health
practices and determine the applicability of regulatory limitations prior to use.
1 Scope
This International Standard describes a method for the determination of the corrosiveness to copper of liquefied
petroleum gases.
NOTE - For an equivalent copper strip test applicable to less volatile petroleum products, see IS0 2160.
2 Normative references

3 Definition
For the purposes of this International Standard, the following definition applies.
3.1 liquefied petroleum gas (LPG): Hydrocarbon gas that can be stored and/or handled in the liquid phase under
moderate conditions of pressure and at ambient temperature. It consists essentially of C3 and Cd alkanes or
alkenes, or a mixture of t
