1.1.1 Procedure AThe "Heavy Duty" procedure describes the test option for fabrics over 240 g/m² (7 oz/yd²) or fabrics which should meet heavy duty end-use conditions of wear.

1.1.2 Procedure BThe "Light Duty" procedure describes the test option for fabrics under 240 g/m² (7 oz/yd²) or fabrics which should meet light duty end-use conditions of wear.

1.2 The test method is intended for both regular, ribless woven corduroy or other woven pile fabric constructions.
