. It specifically addressed equipment using polyester, epoxy, or furane resin systems reinforced with glass fibres, typically manufactured via the wet lay-up or filament winding process. Core Specifications & Scope Operating Conditions:
is a critical British Standard for the design and construction of vessels and tanks made from Glass-Reinforced Plastic (GRP) . While it has largely been superseded by the European standard EN 13121 , it remains a highly regarded reference for GRP engineering due to its stringent safety factors and detailed calculation methods.
