Environmental Condition Effects on Textile Test Uncertainty
topic
Environmental uncertainty contributions to textile test results arise from variations in conditioning temperature and relative humidity that alter fibre moisture regain and mechanical properties within and between tests; temperature and humidity sensitivity coefficients derived from controlled experiments quantify the partial derivatives needed to propagate environmental variation through textile measurement uncertainty budgets.
Role
Quantifies the humidity and temperature sensitivity of textile mechanical property measurements that require conditioning under ISO 139 standard atmosphere, enabling laboratories to determine whether their environmental control precision is adequate for the target measurement uncertainty and identifying when environmental uncertainty is a dominant budget component requiring infrastructure improvement.
