What is ISO 16536 – Thermal insulating products about?
ISO 16536 is an international standard on building applications that discusses the determination of long-term water absorption by diffusion for thermal insulating for building applications. Thermal insulating helps in slowing down the rate of heat loss from a hot surface and similarly reduce the rate of heat gain into a cold body.
ISO 16536 specifies the equipment and procedures for determining the long-term water absorption of test specimens by diffusion. It is applicable to thermal insulating products. It is intended to simulate the water absorption of products subjected to high relative humidities, approximating to 100 %, on both sides and subjected to a water vapour pressure gradient for a long period of time e.g., inverted roof or unprotected ground insulation.
NOTE: The test is not applicable for all types of thermal insulating products. The relevant product standard should state for which of its products, if any, this test is applicable.
Who is ISO 16536 – Thermal insulating products for?
ISO 16536 on thermal insulating products is applicable to:
- Manufacturer of thermally insulated products
- Design engineer
Why should you use ISO 16536 – Thermal insulating products?
Thermal insulation reduces the unwanted heat loss or heat gain through a building envelope. ISO 16536 in turn reduces the energy demand for cooling and heating of buildings, and this is a mitigation measure to reduce greenhouse gas (GHG) emissions.
ISO 16536 navigates you through the principles of long-term water absorption by diffusion. It is determined by measuring the increase in the mass of a test specimen subjected to a water vapour pressure difference and temperature gradient for 28 days.
With obedience and compliance to ISO 16536, you can efficiently manufacture high-quality products for building applications. In this manner, you can make sure that your products consistently meet and exceed quality expectations.
