    ASTM D3982

    Abstract

    This specification covers the material and design requirements, and fabrication of ducts and hoods made of "fiberglass" (glass fiber reinforced thermosetting resin) consisting of a polyester, vinyl ester, or other qualified resin-matrix systems with fiber reinforcement manufactured by contact molding, intended for use in handling corrosive fumes and process gases. Special attention is given to equipment that operates at specified temperatures with regard to strength and corrosion resistance. This specification does not address the selection of resins and reinforcements for specific chemical environments.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers ducts fabricated by contact molding intended for use in handling corrosive fumes and process gases. Special attention is given to equipment that operates at temperatures over 180°F (82.2°C) with regard to strength and corrosion resistance.

    1.2 The material of construction shall be “fiberglass” consisting of a polyester, vinyl ester, or other qualified resin-matrix systems with fiber reinforcement in accordance with Specification C582.

    1.3 This specification is not intended to cover selection of resins and reinforcements for specific chemical environments.

    1.4 This specification covers ducts up to a design pressure of ±5 psig (34.5 Pa).

    1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.6 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 1There is no known ISO equivalent to this standard..
