About This Item
ASTM D3840 is the ASTM standard for Standard Specification for “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Pipe Fittings for Nonpressure Applications. It provides a technical basis for describing and evaluating pipe fittings made from glass-fiber-reinforced thermosetting resin when they are intended for nonpressure service. This matters because buyers, manufacturers, and specifiers need a clear reference for product expectations, helping support consistency, quality control, and more informed procurement decisions.
Purpose of ASTM D3840
The purpose of ASTM D3840 is to define a specification framework for fiberglass pipe fittings used in nonpressure applications. As a product-focused ASTM standard, it helps establish a common technical reference for materials and fittings described by the standard title. That can support more consistent product identification, comparison, and acceptance during purchasing or manufacturing. For teams working with glass-fiber-reinforced thermosetting-resin fittings, the document helps align expectations around specification compliance and basic performance suitability.
Common use cases of ASTM D3840
This standard is commonly used when selecting or specifying fiberglass pipe fittings for systems that do not operate under pressure. It is relevant to procurement, product cataloging, and quality review where the fitting material and application need to match the standard’s scope. ASTM D3840 may also be used by manufacturers and distributors preparing product documentation for glass-fiber-reinforced thermosetting-resin fittings, especially when the goal is to reference a recognized ASTM specification in a nonpressure piping context.
Why ASTM D3840 matters
ASTM D3840 matters because it gives stakeholders a shared specification point for a defined class of pipe fittings. In practice, that can reduce ambiguity in purchasing and product evaluation, support consistency across supply chains, and help quality control teams check whether fittings are being described against the correct standard. For nonpressure applications, having a clear ASTM reference also supports better compliance communication and lowers the risk of selecting an unsuitable product for the intended service.
