Method for measurement of the equivalent pore size of fabrics (bubble pressure test)What is BS 3321 Bubble pressure test of fabrics about? BS 3321 is an international standard that focuses on the measurement of the equivalent pore size of fabrics (bubble pressure test). BS 3321 describes a method for the measurement of the equivalent pore radius, which provides an estimate of the size of the interstices in all types of fabric which are permeable to air. The method is particularly applicable to water repellent and filter fabrics. Who
