BS 3958 is a British Standard series that discusses thermal insulating materials. The main objective of the BS 3958 series is to provide best industry requirements that ensure the insulating materials are fit for purpose, such that they offer adequate thermal and acoustic insulation, as per the specfic needs of the end-application.
BS 3958-2 is the second part of the series that specifies specifies composition, moisture content, physical and chemical requirements for two types of calcium silicate preformed insulation.
BS 3958-2 on calcium silicate preformed insulation is relevant to:
Calcium silicate is commonly used as a safe alternative to asbestos for high temperature insulation materials, that offers excellent thermal and corrosion resistant properties. Industrial grade piping and equipment insulation is often fabricated from calcium silicate given that the operating temperatures may go as high as 1000°C. However, to meet your specific insulation needs and requirements, it is vital that you choose the right materials based on their performance when exposed to certain temperatures.
For this purpose, BS 3958-2 classifies the material into two types i.e Type I and Type II and provides its respective thermal conductivity values and mean temperatures.
BS 3958-2 also walks you through best industry physical and chemical requirements, along with dimensional tolerances, standard shapes and sizes, and recommendations on moisture content and composition of calcium silicate preformed insulation slabs.
Guidance on test methods for determining the alkalinity is also covered.
Thus, if you are a manufacturer of thermal insulating materials, compliance with BS 3958-2 can ensure your products and materials are fit for the intended application use.
