Tensile testing measures the force needed to elongate and break a sample. It is used to determine the strength and elasticity of woven or non-woven fabrics, plastic film or sheeting, gloves, condoms and other materials.
Nelson Laboratories tests fabrics by the strip method (EN 29073 or ISO 9073) or the grab test (ASTM D5034, D5035). Plastics are tested according to ASTM D882, ASTM D638. Fabrics are tested wet or dry. We are an active member of ASTM committees.

Study OutlineThin plastic films are tested by cutting a ½ inch wide strip. Thickness is measured at three locations. The speed and grip distance vary depending on the %elongation of the sample. Samples are pulled until break and the breaking factor, tensile strength, tensile at break, elongation and modulus are reported.
Thicker plastics are cut with the ASTM D412 die C. Marks are made 1 inch apart and the median of three thickness measurements is used in calculating the cross-sectional area. The instrument is set up with the crosshead speed to 20 inches per minute and the specimen is inserted into the grips. The elongation of the specimen is measured between the marks with an extensometer.
Fabric samples are cut to 4 x 6 inches in both the machine and cross directions. The instrument is set to 12 inches per minute and the specimen is inserted into the 1 x 1 inch grips. The sample is pulled until break and the breaking force and elongation are measured.
