    Abstract

    This specification covers "fiberglass" (glass-fiber-reinforced thermosetting-resin) pressure pipe fittings for use with filament wound or centrifugally cast fiberglass pipe. The fibreglass fittings are defined by type, grade, class, category, and pressure rating: type 1 - filament-wound fittings, type 2 - compression moulded fittings, type 3 - resin transfer molded fittings, type 4 - centrifugally cast fittings, and type 5 - contact molded fittings; grade 1 - epoxy-resin, grade 2 - polyester-resin, grade 3 - phenolic-resin, grade 4 - vinylester resin, and grade 7 - furan resin; class A - no liner, class B - polyester-resin liner (nonreinforced), class C - epoxy-resin liner (nonreinforced), class D - phenolic resin liner (nonreinforced), class E - polyester-resin liner (reinforced), class F - epoxy-resin liner (reinforced), class G - phenolic resin liner, class H - thermoplastic-resin liner, class I - furan-resin liner (reinforced), class J - vinylester resin liner (nonreinforced), and class K - vinylester resin liner (reinforced); category 1 - taper-to-taper adhesive bonded joint fittings, category 2 - straight-taper adhesive-bonded joint fitting, category 3 - straight adhesive bonded joint fitting, category 5 - flanged fittings, category 6 - elastomeric sealed joints with sealant, and category 7 - elastomeric sealed joints with seals. Short-term hydrostatic strength test and cyclic or static pressure test shall be performed to meet the requirements prescribed.

    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 fiberglass (glass-fiber-reinforced thermosetting-resin) fittings for use with filament wound or centrifugally cast fiberglass pipe, or both, in sizes 1 in. through 24 in. for pipe manufactured to Specification D2996 or D2997, or both.

    1.2 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.

    1.3 The following safety hazard caveat pertains only to the test method portion, Section 7, of this specification:

    1.4 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 1—The term fiberglass pipe as described in Section 3 of this specification applies to both reinforced thermosetting resin pipe (RTRP) and reinforced polymer mortar pipe (RPMP).

    Note 2—For the purposes of this standard, ploymer does not include natural polymers.

    Note 3—There is no known ISO equivalent to this standard.

    A1.1.1 This test determines whether the degree of cure of a fiberglass fitting test specimen meets the quality control requirements determined by statistical analysis of typical production products.
