1.1 This specification covers compression molding thermosetting, urea-formaldehyde molding compounds as further defined in
3.1.
1.2 The values stated in SI units are to be regarded as the standard. NOTE 1—The properties included in this specification are those required to identify the types of molding compounds covered. There may be other requirements necessary to identify particular characteristics. Transfer or injection molding will usually result in different physical and electrical characteristics than compression molding.
1.3 The following safety hazards caveat pertains only to the test method portion, Section 7, of this specification: 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. NOTE 2—ISO 2112-1977(E) is similar but not equivalent to this specification. Product classification and characterization are not the same.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
