BS EN 1604 is a European Standard that discusses thermal insulation products for buildings. The main aim of the BS EN 1604 series is to provide manufacturers with best industry practices to demonstrate the performance of thermal insulation products, such that they are fit for its intended use.
BS EN 1604 specifies the equipment and procedures for evaluating dimensional changes of test specimens under specified conditions of temperature, relative humidity and duration of exposure.
BS EN 1604 is applicable to thermal insulating products.
BS EN 1604 on thermal insulation products is relevant to:
Insulation performance and system integrity is directly related to the dimensional stability of the insulating material. Maintaining shape and constant dimensions over very long periods of time are key requirements for insulating materials, particularly when they are exposed to considerable variations in temperature.
In this regard, BS EN 1604 specifies the apparatus requirements to test thermal insulating specimens along with their number, dimensions and conditioning and test procedure.
BS EN 1604 proposes a range of conditions from which one or more desirable test conditions can be selected.
Thus, if you are a manufacturer of products for thermal insulation, complying with BS EN 1604 can help demonstrate the performance and credibility of your product, ensuring that they are fit for purpose.
Overall, dimensional stability can prevent swelling, expansion, shrinkage and buckling of the insulation.
