ASQ, the American Society for Quality, is a nonprofit organization that develops and publishes standards used for quality control in a wide array of industries. Headquartered in Milwaukee, United States, ASQ standards are used by its approximately 85,000 members. In line with its work with quality control standards, ASQ runs an extensive certification program to assure its standards for quality control are met. ASQ also serves as the administrator for the U.S. TAGs (United States Technical Advisory Group) to ISO/TCs 69, 176 and 207 (International Organization for Standardization/Technical Committee) and to all but one of their subcommittees. Standards from ASQ are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: StandardsSubscriptions@ansi.org or 1-212-642-4980 or Request Proposal Price.

Sampling Procedures and Tables for Inspection by Attributes

Sampling Procedures and Tables for Inspection by Attributes is an acceptance sampling system to be used with switching rules on a continuing stream of lots for AQL specified. 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 and Z1.9 - Sampling Procedures and Tables Package

ANSI/ASQ Z1.4 and Z1.9 - Sampling Procedures and Tables Package

The ANSI/ASQ Z1.4 and Z1.9 - Sampling Procedures and Tables Package establishes sampling plans and procedures for inspection by variables and attributes for use in procurement, supply, storage and maintenance operations. Tables are also provided to guide in the process of measuring, examining and testing. This package includes ANSI/ASQ Z1.4-2003 (R2013) and ANSI/ASQ Z1.9-2003 (R2013).


ANSI/ASQ Z1.9-2003 (R2013)

Sampling Procedures and Tables for Inspection by Variables for Percent Nonconforming

Sampling Procedures and Tables for Inspection by Variables for Percent Nonconforming is an acceptance sampling system to be used on a continuing stream of lots for AQL specified. 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/ASQC Q3-1988

Sampling Procedures and Tables for Inspection of Isolated Lots by Attributes

Sampling plans designated in this publication, are applicable, but not limited, to inspection of the following: end items, components and raw materials, services, materials in process, supplies in storage, data or records, administrative procedures.


ANSI/ASQC S2-1995

Introduction to Attribute Sampling

Section one gives general information on methods of acceptance sampling inspection with particular reference to the sampling procedures and table for inspection by attributes given in ANSI/ASQC Z1.4, Z1.9, Q3, and S1 as well as ISO 8422. This document explains the terms used, describes the various schemes and plans, gives practical advice on sampling inspection and discusses some of the theoretical aspects. Section two extends the introduction to acceptance sampling in Section one and amplifies the introductory text and instructions contained in ANSI/ASQC Z1.4, by giving detailed comments and examples to assist in using the method of sampling inspection that constitutes the ANSI/ASQC Z1.4 sampling system.
