If a lot of paper is to be accepted or rejected on the basis of a series of tests made on the paper, it is important to sample the paper in a way that will give a test result that is representative of the lot of paper.

1.1 This practice covers a procedure for obtaining a sample to represent a lot of paper or paperboard, fiberboard, or related product, including converted paper products (all hereafter referred to as paper).

1.2 Prior to purchase, there should be agreement between buyer and seller on the size of the lot to be sampled (5.1), on details of the sampling procedure, the required physical and chemical properties, dimensional tolerances, etc., and the test methods to be employed.

1.3 Appendix X1 and Appendix X2, which provide useful, statistical criteria for accepting individual lots of paper on the basis of the number of defective test units, can assist the buyer and the seller in selecting an agreed-upon sampling and acceptance procedure.

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.
