This standard describes the minimum requirements for fiberglass-reinforced plastic wash-water troughs and launders made by the contact-molding process, including flat-bottom, round-bottom, and V-bottom troughs and launders. Requirements are included for materials, properties, design, construction, dimensions, tolerances, work quality, and appearance.

This standard also describes the requirements for using general-purpose and chemical-resistant resins. These fabrications are generally used in municipal water supply service and industrial water supply service applications.
