Full title and description

ISO 9915:1992 — Aluminium alloy castings — Radiography testing. Specifies general rules for performing radiographic inspection of aluminium alloy castings and provides technical specifications and acceptance guidance including illustrative annexes (reference radiographs, grading of discontinuities, combination procedures and design of image quality wire indicators).

Abstract

This standard gives the practical radiographic inspection practice for aluminium alloy castings, defines requirements for equipment and exposure, and sets out methods and criteria for classification and acceptance of discontinuities. Annexes include an extract of ASTM E 155 (reference radiographs), grading tables for limiting acceptable discontinuities, worked examples for combining discontinuities and an example design for image‑quality wire indicators.

Scope

Applies to radiographic testing of aluminium alloy castings. It covers the recommended inspection practice (preparation, exposure, film handling and examination), specification of technical parameters to be agreed between purchaser and supplier, image quality indicators, and acceptance grading for discontinuities in castings. The standard is intended to be used where radiography is chosen as the method for internal defect detection and evaluation.

Key topics and requirements

• General radiographic inspection practice for aluminium alloy castings (preparation, positioning, exposure and film handling).
• Image quality requirements and design/examples of image‑quality wire indicators (IQIs).
• Acceptance grading tables for limiting acceptable discontinuities specific to aluminium castings.
• Examples and procedures for combining discontinuities when assessing acceptability.
• Reference extract of ASTM E 155 (standard reference radiographs for aluminium and magnesium castings) as supporting material.

Typical use and users

Used by foundries, casting quality engineers, NDT (radiography) technicians and inspectors, contract inspection bodies, and design/quality managers specifying acceptance criteria for aluminium cast components. It is a practical guidance document for organizations that choose radiography to assess internal casting integrity.

FAQ

Q: What is this standard?

A: ISO 9915:1992 is an ISO document that provided rules and practical guidance for radiographic inspection of aluminium alloy castings, including acceptance grading and illustrative annexes.

Q: What does it cover?

A: It covers radiographic inspection practice (preparation, exposure, film handling and examination), image quality indicators, grading/acceptance of discontinuities and worked examples; Annex A reproduces an extract of ASTM E 155 and other annexes provide grading tables and examples.

Q: Who typically uses it?

A: Foundries, NDT service providers, inspection and quality personnel in manufacturing and procurement who need to specify or carry out radiographic examination of aluminium castings.

Q: Is it current or superseded?

A: At the ISO level ISO 9915:1992 is listed as Withdrawn (stage 95.99). Users should verify current national adoptions or later national/sector standards — for example, there are national/adopted documents carrying the same numeric designation in some jurisdictions (e.g., a KS D ISO 9915 edition), so check the relevant national standards body for current versions or replacements.

Q: Is it part of a series?

A: It is part of the body of ISO work on non‑destructive testing of castings and metallic materials (see related ISO NDT standards such as ISO 5579, ISO 4993 and ISO 10049). It is cross‑referenced with ASTM reference material for castings inspection.

Q: What are the key keywords?

A: Radiography, aluminium alloy castings, image quality indicator (IQI), discontinuity grading, acceptance criteria, non‑destructive testing (NDT).
