For decades, served as the definitive international benchmark for the engineering of Glass-Reinforced Plastic (GRP) vessels. Before its introduction, the design of composite tanks was often hampered by the lack of a unified methodology, leading to inconsistent safety margins. BS 4994 revolutionized the field by introducing the "unit property" concept, moving away from simple thickness specifications to a more rigorous analysis of the laminate's load-carrying capacity.

BS 4994 is a British Standard specification. It outlines the design, construction, inspection, and testing of vessels and tanks made from reinforced plastics. The standard specifically addresses the integration of a chemical resistant liner with a GRP structural laminate.
Even though BS 4994:1987 was officially withdrawn and replaced by EN 13121 , it continues to be the backbone of many GRP (Glass Reinforced Plastic) tank specifications globally. ABSTRACT - NPL Publications

The standard specifically addressed materials manufactured by the , using resin systems like polyester, epoxy, or furane, reinforced with glass fibres. It accounted for the anisotropic nature of laminar composites, using a design method that became highly influential and is still respected for its reliability in vessels built to its guidelines.
