ASTM D3754, Spécification normalisée pour les conduites d’évacuation et les tubes sous pression industriels « en fibre de verre » (en composites thermodurcissables à renforts de fibre de verre) (Revision 2019)

Remplace ASTM D3754 ( de mars 2014).

Standard specification for “fiberglass” (glass-fiber-reinforced thermosetting-resin) sewer and industrial pressure pipe

This specification covers machine-made fiberglass pipe, 8 in. (200 mm) through 156 in. (4 000 mm), for use in pressure systems for conveying sanitary sewage, storm water, and many industrial wastes, and corrosive fluids. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are fiberglass pipes. This standard is suited primarily for pipes to be installed in buried applications, although it may be used to the extent applicab le for other installations such as, but not limited to, jacking, tunnel lining and slip-lining and rehabilitation of existing pipelines. Pipe covered by this specification is intended to operate at internal gage pressures of 450 psi (3103 kPa) or less.

ASTM D4385, Pratique normalisée pour la classification des défauts visuels dans les produits pultrudés en plastiques renforcés thermodurcis (Revision 2019)

Remplace ASTM D4385 ( de novembre 2013).

Standard practice for classifying visual defects in thermosetting reinforced plastic pultruded products

This practice covers acceptance criteria for visual acceptance of thermosetting reinforced plastic pultruded rods, bars, shapes, and sheets. It presents definitions of possible defects to serve as a guide for contracts, drawings, product specifications, and final inspection.
