BS 3430:1995 Method for sampling to determine the average quality of paper and board
Printed version of this is available at library. To request, please e-mail to referencepk@usm.my and include a copy of this record in your e-mail.
This International Standard specifies a method of obtaining a representative sample from a lot of paper or board for testing to determine whether or not its average quality complies with set specifications including solid and corrugated fibreboard (see ISO 4046).
For some tests, special methods of sampling may be necessary; these will be given in the International Standard for the appropriate method of test.
NOTE 1 If less than 50 % of the lot is available for sampling, then sampling will be invalid in the absence of agreement to the contrary.
This method is unsuitable for determining the variability within a lot.
NOTES
2 Information on sampling for other purposes is given in ISO 2859-1:1989, Sampling procedures for inspection by attributes - Part 1: Sampling plans indexed by acceptable quality level (AOL) for lot-by-lot ISO 2859-2:1985, Sampling procedures for inspection by attributes - Part 2: Sampling plans indexed by limiting quality (LQ) for isolated lot inspection, ISO 2859-3:1991. Sampling procedures for inspection by attributes - Part 3 Skip-lot sampling procedures, and ISO 3951:1989, Sampling edures and charts for inspection by variables for percent nonconforming
Information on the preparation of test pieces is given in the appropriate standard test methods.
