The standard is widely used in the industry for designing and constructing reinforced plastics vessels and tanks for various applications, such as chemical storage, water treatment, food processing, etc. The standard provides guidance on the selection of materials, design methods, fabrication techniques, quality control, testing procedures and installation practices. The standard also categorizes vessels in relation to duty and defines four classes of vessels: Class I (severe duty), Class II (moderate duty), Class III (light duty) and Class IV (very light duty).
However, the standard is not available for free online. The official PDF version of the standard can be purchased from the [Information Provider website] for NZ$ 292.00.
