Objectives

In this live online course, you will learn the fundamentals of AQL Testing in Packaging/Device Control. AQL testing as part of the incoming good inspection process is commonly used. But still, questions often arise. It is this webinar’s aim to aid here and to explain statistical fundamentals behind the AQL testing concept, like, for example:
  • Definition of AQL – what does it mean in regard to the accepted lot? What is the level of possible defects?
  • How to use defect evaluation lists?
  • How are quality levels determined and how is the number of units to be inspected calculated?
  • What does AQL testing look like for supplier and user?
  • What has to be done when AQL limits are exceeded?

Background

Usually, the responsibility of ensuring the container/device quality upon delivery to users (e.g. pharmaceutical companies) rests with the manufacturers (suppliers) of packaging materials. However, users are held responsible by regulatory requirements to ensure suitability of containers/devices for their products. Therefore, users should conduct sampling of incoming packaging/ device lots to confirm their acceptability according to predetermined quality agreements.
 
Expecting defect-free containers from a supplier does not eliminate the need for some degree of incoming and online inspection, as well as post-packaging inspection. However, acceptance sampling of incoming batches by users has its limitations. Care should be taken to understand the “risks” of the sampling plan and the defined defect class / Acceptable Quality Levels (AQLs). Every AQL testing contains the statistical possibility of accepting a lot that is “bad” or rejecting a lot that is “good” (consumer’s and producer’s risk).
 
Since it is not practical to inspect incoming lots to 100% and to expect container lots to be free of imperfections, it is important that users and suppliers consistently define sample sizes, attributes and AQLs. Defect evaluation lists containing sample sizes, defect classes (Critical, Major or Minor), attributes and AQLs can provide such consistency.

Target Group

This online event is designed for all employees working in the pharmaceutical industry (including drug device combination products), for suppliers of packaging materials & devices and to all who have to deal with the manufacture, quality assurance/ control and release of packaging materials /devices.

Technical Requirements

We use Webex for our live online training courses and webinars. At www.gmp-compliance.org/training/online-training-technical-information you will find all the information you need to participate in our events and you can check if your system meets the necessary requirements to participate. If the installation of browser extensions is not possible due to your rights in the IT system, please contact your IT department. Webex is a standard nowadays and the necessary installation is fast and easy.
