Standard Test Method for Determining Corrosive Effect of Combustion Products Using the Cone Corrosimeter

Importancia y uso:

5.1 The metal loss from corrosion is directly related to the increase in electrical resistance of the target due to the decrease in conductive cross-sectional area.

5.2 The relationship between resistance increase of metallic targets used in this test method and the amount of metal loss as reported by a uniform loss in thickness has not been determined.

5.3 This test method is used to determine the corrosive effect of combustion products from burning electrical insulations or coverings or their constituent materials or components. Corrosion is determined by the reduction of thickness of the metal on standardized targets, as measured by electrical resistance. These targets are not necessarily representative of the intended end use.

5.4 This test method is intended for use in electrical insulations or coverings material and product evaluations, for additional data to assist in design of electrical insulations or coverings products, or for development and research of electrical insulations or coverings products.

5.5 A value of the initial test heat flux is selected to be relevant to the fire scenario being investigated (up to 100 kW/m²). Additional information for testing is given in A1.2.3.
