BS 4994 laid the groundwork for the safe use of composite materials in industrial storage. While it has been superseded by EN 13121, its engineering principles remain a cornerstone of composite design. For accurate and legal reference, professionals should consult official BSI platforms or educational institutions rather than relying on unauthorized online copies.

In the field of industrial engineering and storage solutions, is a critical standard that governs the design and construction of vessels and tanks made from glass-reinforced plastics (GRP), also known as Fiber Reinforced Plastics (FRP). Originally developed in the United Kingdom, this standard has been a benchmark for ensuring the safety, durability, and integrity of composite structures used in highly corrosive environments, such as chemical processing and water treatment plants.

BS 4994 (specifically BS 4994:1987, the most widely cited version) is titled "Specification for design and construction of vessels and storage tanks in reinforced plastics." It provides a comprehensive code of practice for engineers and manufacturers to calculate the required thickness of laminate, select appropriate resins, and design joints and supports for composite vessels.
It is important for engineers and procurement officers to note that as an active British Standard. It has been superseded by the European standard BS EN 13121 .
Unlike steel tanks, where properties are relatively uniform, FRP tanks are anisotropic (their properties differ depending on the direction of the reinforcing fibers). BS 4994 provides the methodology to account for these directional strengths, ensuring the vessel can withstand internal pressure, hydrostatic loads, and wind loads without failure.
