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 3958-1 is the first part of the series that specifies composition, moisture content, physical and chemical requirements for magnesia preformed insulation slabs, lags and pipe sections, generally for use up to about 315 °C.
BS 3958-1 on magnesia preformed insulation slabs is relevant to:
Magnesia preformed insulation materials are a commonly used for its excellent acoustic and thermal insulation properties. 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 3958-1 classifies the material into four groups according to its thermal conductivity and temperature range.
BS 3958-1 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 magnesia preformed insulation slabs
Guidance on test methods for determining the alkalinity and composition is also covered.
Thus, if you are a manufacturer of thermal insulating materials, compliance with BS 3958-1 can ensure your products and materials are fit for the intended application use.
