The current IAQG 9138:2018 standard establishes requirements when implementing statistical product acceptance methods to meet defined risk requirements. This standard also establishes the minimum content required to be covered in an organization’s documented procedures that govern their application of statistical product acceptance methods. These general requirements and documented procedures meet the associated requirements of the 9100/9110/9120 quality management system standards. This 9138 standard is applicable when invoked in a purchasing contract or specification, contractual document, customer agreement, or adopted by the organization.
The IAQG’s published 9138:2018 standard revision effort will:
• utilize the new SDO process and numbering convention (i.e., IA9138 format)
• ensure alignment with IA9100, IA9103 and IA9145 standards;
• incorporate references to existing SCMH and deployment support materials;
• incorporate new tools to support regulatory and customer changes relative to the 9138:2018 standard.
The completed, revised standard must
• be compatible with the IAQG strategy and mission;
• be suitable for all sizes and types of organizations in the aviation, space, and/or defense sectors;
• achieve recognition by the affected authorities.
The scope and intent of the 9138 standard revision is to:
• make changes needed to address new requests
• improving the clarity of terminology
• incorporation of tools developed since standard release; and
• assure that the resultant standard will allow a common interpretation by all stakeholders.
Rationale: This standard is an upgrade and replacement for 9138 Statistical Product Acceptance Requirements published by the International Aerospace Quality Group (IAQG) in 2018. Technically equivalent standards are published in all International Aerospace Quality Group (IAQG) sectors (i.e., Americas, Asia-Pacific, Europe). Reasons for revising this standard include the following:
1. New tools have been developed to respond to expanded requests in this discipline from regulatory agencies and some customers. The use of these tools will be optional except as specified by these external authorities.
2. Existing tools have in some cases been improved or clarified.
3. The increasing interaction with IA9100, IA9103 and IA9145 teams calls for periodic updates to definitions and terminology, to improve the support that IA9138 will provide to those other teams.
