ISO 11503-1995 “Determination of temperature resistance of paints and varnishes (intermittent condensation method)”

A Preface
ISO (International Organization for Standardization) is a global alliance of national standards bodies (ISO member bodies). The development of international standards is usually carried out through ISO technical committees. Each member institution interested in a subject on which a technical committee has been established has the right to be represented in the committee. Government and non-governmental international organizations that liaize with standardization organizations are also involved in this work. ISO works closely with the International Electrotechnical Commission (IEC) on all matters of electrical standardization.

Draft international standards adopted by the Technical Committee will be circulated to member bodies for voting. Publication as an international standard requires approval by at least 75% of member institutions.

The international standard ISO11503 was developed by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes.

Annex A is an integral part of this international standard.

ISO 11503-1995 “Determination of temperature resistance of paints and varnishes (intermittent condensation method)”

There is rarely a direct relationship between the resistance of organic coatings to the action of humidity and the ability to deteriorate in other environments. This is because the impact of each of the several factors that influence the progression of deterioration varies considerably depending on the conditions encountered. Therefore, the results obtained in this test should not be taken as a direct guide to testing the tolerance of coatings in all environments where these coatings may be used. Furthermore, the performance of the different coatings under test should not be a direct guide to the relative performance of these coatings in service. However, the described method provides a means of checking whether the quality of the paint or paint system is maintained.

1 Scope
This international standard is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products.

It specifies a test method for determining the resistance of single or multi-layer coating systems of paints or related materials to intermittent water condensation under standard conditions. The method consists of testing the coating on non-porous and porous substrates.
