Thermal Comfort of Textile Materials and Its Assessment in dynamic environmental conditions has been discussed in previous two articles. For the correct assessment of the thermal properties, global testing standards are must. These standards are not only useful for thermal assessment but also used for comparison of various products at same platform and are accepted unambiguously. The article discusses various popular standards used for different products in different environmental conditions.
Thermal manikins have proved to be a useful tool in simulation of human body while testing of thermal properties in varied environmental conditions. Some popular thermal manikins have also been discussed in this article.
Thermal Testing Standards
For a comparison a reference point is needed, which can be taken as benchmark to compare the parameters for a given product. Any property or parameter can be evaluated against the standard provided that the standard is developed with consensus and acceptable by all. It may be a characteristic, property or parameter like length or with of any object or colour of any object.
Targeting this objective, same is followed with the testing standards also. Different material's performance can be tested or evaluated differently, but to keep all the results on one platform and for true judgement, the procedure of testing, specifications, equipment used, testing conditions has to be uniform and well defined.
So, if the test has been conducted by following the standard instructions as described in the procedure, the results will not vary with the change of testing location, person, equipment etc.
In the thermal testing of textile materials various test standards are developed and are globally valid.
