Acceptance Sampling for Quality Auditors & Inspectors

One Day Training Course


Acceptance sampling is a widely used technique for the inspection of incoming and outgoing product. Sampling standards, such as ANSI/ASQ Z 1.4 for inspection by attributes, are used to select sample sizes. The sampling standards are based around the concept of the AQL (Acceptable Quality Limit). It is important that the AQL is suitably established, and that the appropriate sample sizes are chosen so that correct decisions are made on the acceptance or rejection of lots. This course will provide detailed information on the correct procedures to be followed in choosing samples sizes.

Learning Outcomes

On successful completion of this training course, delegates should be able to:

  • Select sampling sizes for inspection using the international sampling plans, such as ANSI/ASQZ1.4, ISO 2859, or BS 6001
  • Implement sampling procedures based on AQL’s
  • Demonstrate understanding of the switching rules and use of the normal, tightened and reduced sampling tables

Who Should Attend


  • Staff who have responsibility for selecting sample sizes for inspection of incoming or outgoing lots of product
  • Quality engineers and quality auditors
  • Quality assurance staff responsible for setting acceptable quality limits (AQL’s)

Course Programme

  • Introduction to the statistics relevant to inspection by attributes and variables
  • Explanation of sampling inspection system terminology including; acceptance quality limit (AQL), inspection levels, attributes, variables, probability of acceptance, operating characteristic (OC), random sampling
  • The correct approach to determining the acceptance quality limit (AQL)
  • Identifying the appropriate inspection level and sample sizes in the sampling tables
  • Exercises in the use of the sampling tables selecting the appropriate sampling plans for inspection by attributes and variables. How the tables are used to decide on acceptance or rejection of a lot
  • How to correctly use the switching rules for optimum effectiveness

Most of the course time will be devoted to the standard for inspection by attributes, as this is the standard most commonly used in industry. However, examples from the standard for inspection by variables will also be studied, and the circumstances in which the standard for inspection by variables is used will be explained.

Course Times

9.00am - 5.00pm

Public Course Cost

€395 (includes course documentation, lunch and refreshments)

In-House Courses

For In-House courses the tutor will contact you in advance to discuss the course programme in more detail in order to tailor it specifically for your organisation.

Course Manual

Delegates will receive a very comprehensive course manual, which explains the statistics underlying sampling plans, describes in detail how the sampling tables for both attributes and variables are used, incorporates worked examples of selecting appropriate sampling plans for given AQL’s, and shows how the switching rules are correctly used. The manual will contain copies of the relevant tables from the current versions of ANSI/ASQ Z1.4 and the ANSI/ASQ Z 1.9 standards.
