Equipment or pipe work with an operating temperature greater than 55 °C in case of metallic surfaces and 65 °C in the case of non-metallic surfaces should be insulated so that the surface temperature after insulation (cold surface temperature) does not exceed 55 °C.It is recognized that temperatures of 60 °C or greater will result in extreme discomfort to personnel and therefore a maximum cold surface temperature of 55 °C should be considered as prudent.

Typical products to be used for applications are calcium Silicate, Ceramic Fibre Blanket, Cellular Glass, Glass Wool, Perlite, Stone Wool, Rock Wool or Vermiculite.
