ASTM D5485-16

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

SIGNIFICANCE AND USE
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 heating 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.
SCOPE
1.1 This fire-test-response standard measures the corrosive effect by loss of metal from the combustion products of materials, components, or products.  
1.2 This test method provides corrosion results of product and material specimens limited to a maximum size of 100 by 100 mm in area and 50 mm thick.  
1.3 Additional information regarding the targets, the test conditions, and test limitations is provided in the annex.  
1.4 The results of this test method have not been investigated with respect to correlation to actual fires.  
1.5 An ISO standard exists, as developed by ISO TC 61 (Plastics), subcommittee 4 (on burning behavior), which is technically very similar to this test method and is designated ISO 11907-4.  
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. (See SI10)  
1.7 This standard measures and describes the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.8 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 7.
