ANSI/ASQ Z1.4-2003 and ANSI/ASQ Z1.9-2003

ANSI/ASQ Z1.4-2003 (Sampling Procedures and Tables for Inspection by Attributes) and ANSI/ASQ Z1.9-2003 (Sampling Procedures and Tables for Inspection by Variables for Percent Nonconforming) have been published.

ANSI/ASQ Z1.4-2003 is an acceptance sampling system to be used with switching rules on a continuing stream of lots for a specified Acceptance Quality Limit .It provides tightened, normal, and reduced plans to be applied for attributes inspection for percent nonconforming or nonconformities per 100 units.

ANSI/ASQ Z1.4-2003 replaces ANSI/ASQC Z1.4-1993 and is available through ASQ for a member price of $88.00. Go to:<http://qualitypress.asq.org/perl/catalog.cgi?item=T004 >.

ANSI/ASQ Z1.9-2003 is an acceptance sampling system to be used on a continuing stream of lots for a specified Acceptance Quality Limit. It provides tightened, normal, and reduced plans to be used on measurements which are normally distributed. Variation may be measured by sample standard deviation, sample range, or known standard deviation. It is applicable only when the normality of the measurements is assured.

ANSI/ASQ Z1.9-2003 replaces ANSI/ASQC Z1.9-1993 and is available through ASQ for a member price of $76.00. Go to:
