Historical Standard: ASTM D705-99 Standard Specification for Urea-Formaldehyde Molding Compounds
SUPERSEDED (see Active link, below)
ASTM D705
1. Scope
1.1 This specification covers compression molding thermosetting compounds consisting of a urea-formaldehyde resin binder intimately combined in the uncured or partially cured condition with fillers, pigments, and other chemical agents.
1.2 The values stated in SI units are to be regarded as the standard. The values stated in parentheses are for information only.
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 and health 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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
