BS EN 61234-1 is a part of IEC 1234.
BS EN 61234-1 describes the method of test for the determination of the hydrolytic stability of plastic films subjected to the simultaneous influence of water and temperature.
With test method described in BS EN 61234-1, the irreversible changes of the mechanical and electrical properties are measured. The test method is applicable to films up to 250 4m thick. Although BS EN 61234-1 was developed for electrically insulating plastic films, as specified, for example, in the series of IEC 674, it may be appropriate for other types of plastic films.
BS EN 61234-1 on test methods for hydrolytic stability of electrical insulating materials is useful for:
Hydrolytic stability is resistance to cured polymer material to reverting to a semisolid or liquid when exposed to high humidity or temperature.
BS EN 61234-1 describes tests to determine the hydrolytic stability of plastic films.
BS EN 61234-1 can help manufacturers test insulating materials to provide best quality products. BS EN 61234-1 can also be used by quality assurance officers to provide ratings and assure safety of the products. Use of BS EN 61234-1 in equipment and appliances make it safer and increases credibility of manufacturers.
