ASTM D4470-97-Reapproved2004<\/h3>\n

Historical Standard: Standard Test Method for Static Electrification<\/h4>\n
\n

ASTM D4470<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the generation of electrostatic charge, the measurement of this charge and its associated electric field, and the test conditions which must be controlled in order to obtain reproducible results. This test method is applicable to both solids and liquids. This test method is not applicable to gases, since a transfer of a gas with no solid impurities in it does not generate an electrostatic charge. This test method also does not cover the beneficial uses of static electrification, its associated problems or hazards, or the elimination or reduction of unwanted electrostatic charge.<\/p>\n

1.2 The values stated in SI units are to be regarded as the standard.<\/p>\n

1.3 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.<\/p>\n
