(Specification)Standard Specification for Laminated Thermosetting Materials
Standard Specification for Laminated Thermosetting Materials
ABSTRACT
This specification establishes the manufacture, property requirements, and testing of several grades of laminated thermosetting materials consisting of two or more plies or layers of reinforcing material such as cellulose paper, cotton fabric, glass fabric, and synthetic fiber fabrics, bonded by a thermosetting synthetic resin. These materials are available in the form of sheets, rolled and molded tubes, and molded rods.
SCOPE
1.1 This specification covers laminated thermosetting materials consisting of two or more plies or layers of reinforcing material bonded by a thermosetting synthetic resin. Examples of such reinforcement are cellulose paper, cotton fabric, glass fabric, and synthetic fiber fabrics. These materials are available in the form of sheets, rolled and molded tubes, and molded rods.
1.2 The values stated in inch-pound units are to be regarded as the standard.
Note 1: This specification resembles IEC 60893-3 in title only. The content is significantly different.
1.3 The following safety hazards caveat pertains only to the test methods described in 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.
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.
