Full title and description

ISO 10049:2019 — Aluminium alloy castings — Visual method for assessing porosity. This International Standard specifies a visual inspection method for assessing porosity on the machined surfaces of aluminium alloy castings; it does not apply to porosity shown on radiograms.

Abstract

This document specifies a visual method for assessing the porosity of the machined surface of aluminium alloy castings, including guidance for inspection and interpretation of results. The method explicitly excludes assessment of porosity detected by radiographic techniques.

General information

• Status: Published (International Standard, confirmed).
• Publication date: June 2019 (ISO, 2nd edition, 2019-06).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 77.040.20 — Non-destructive testing of metals.
• Edition / version: 2 (Second edition, 2019).
• Number of pages: 4 (as published by ISO).

Scope

ISO 10049:2019 provides a standardized visual inspection procedure to assess surface porosity on machined faces of aluminium alloy castings. It defines the inspection area and method of counting/classifying pores and gives criteria for interpreting and reporting results for acceptance or rejection. The standard does not cover porosity evaluation by radiographic or other volumetric NDT methods.

Key topics and requirements

• Definition of inspection area and preparation of machined surfaces for visual assessment.
• Procedure for visual counting and sizing of pores on a specified area (severity levels expressed as number/size of pores per unit area).
• Classification and acceptance criteria for porosity on machined surfaces (severity levels used to interpret acceptability).
• Reporting requirements and recommended contents of inspection orders and records.
• Explicit limitation: method is not applicable to porosity revealed by radiography.

Typical use and users

This standard is typically used by foundries, quality and production engineers, machinists, non‑destructive testing (NDT) technicians, procurement/specification authors, and inspection laboratories involved with aluminium cast components where surface porosity can affect function, finish, or mechanical integrity. It is used to set acceptance criteria, perform routine inspections and prepare inspection reports for cast parts.

Related standards

ISO 10049:2019 replaces ISO 10049:1992 (withdrawn). It is part of the body of standards for non‑destructive testing of metals (ICS 77.040.20) and is typically used alongside other NDT or casting‑specific standards when deeper/volumetric testing is required (e.g. radiographic standards and other ISO/TC 79 outputs).

FAQ

Q: What is this standard?

A: ISO 10049:2019 is an International Standard that defines a visual method for assessing porosity on the machined surfaces of aluminium alloy castings.

Q: What does it cover?

A: It covers the visual inspection procedure, counting/sizing of pores on a specified surface area, classification/severity levels and guidance for interpretation and reporting. It specifically excludes porosity assessment by radiography.

Q: Who typically uses it?

A: Foundries, production and quality engineers, machinists, NDT inspectors and inspection laboratories who need a standardized, repeatable method to assess and document surface porosity on aluminium castings.

Q: Is it current or superseded?

A: ISO 10049:2019 is the current (second) edition, published in June 2019 and confirmed as current during ISO’s periodic review; it replaces ISO 10049:1992.

Q: Is it part of a series?

A: It is part of ISO’s corpus of standards related to non‑destructive testing of metals (work by ISO/TC 79/SC 7). While not a numbered series with sequential titles, it complements other NDT and casting standards and should be used alongside appropriate radiographic or other NDT standards where volumetric assessment is required.

Q: What are the key keywords?
