Determination of mass per unit length and mass per unit area of fabrics
Introduction and background
Textile testing standard method was instituted by the association’s committee on testing of fabrics and textiles to supersede in part AS 1587-1973. Among many existing methods, it recognizes the technical committee’s standardization efforts. The standard concentrates on ISO 3800-1977. Method or Benefits and Principle of test
The method of standardization determines the mass per unit area and mass per unit length of all forms of textile fabric. Specimens of known dimensions are weighed and mass per unit area is determined provided width of fabric is known. Conditioning is performed ad weighing device determines the mass of specimen to + 0.2% accuracy. The specimen in cut to 10000mm2 and operator should avoid excessive handling of specimen.
Testing should be done on five selected integral samples from the fabric in order to represent the complete repeat of patterns fully. Sample conditioning and weighing shall be performed as specified in Australian Standard AS 2001.1 with a + 0.2% accuracy.
Mass per unit area for all the five specimen shall be calculated using the formula mua = m\a
Mass per unit length of each of the five specimen is calculated using the formula in accordance with AS 2001,2,12: mul = mua * w
Summary of the Test Method
After accurate calculations, results shall be presented with reference to Australian Standard AS2001.2.13. In addition, individual results in the appropriate manner as required. To sum up everything, the mass per unit area in g/m2 and mass per unit length in g/m shall be presented for approval on behalf of the council of the standards association of Australian 19th January 1987 and published on 6th April 1987.
