Scope
1.1 This practice covers general methods for specifying textile product characteristics that may be measured or counted.
1.2 There are many different types of acceptance samplings plans. This practice describes five types. (See 1.5.)
1.3 This practice describes general methods for writing the sampling plans of the types named in whose characteristics may be measured or counted. The requirements are described in terms of what the basic unit is and what limit constitutes a nonconforming item. Tables are provided from which appropriate sampling plans can be designed. Numerical examples illustrate the design of sampling plans and the construction of their consequent operating characteristic curves.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
