Overview

EN ISO/ASTM 52919:2025 - Additive manufacturing - Qualification principles - Test methods for metal casting sand moulds - is a CEN-endorsed standard that specifies test methods and qualification principles for AM-made sand moulds used in metal casting. The document addresses mechanical and physical properties (including, but not limited to, tensile strength, transverse/bending strength, gas permeability and thermal expansion) and provides guidance on sampling, testing and documentation for parts produced by additive manufacturing processes.

Key Topics

Test methods: Applicability of established test procedures for tensile, bending/transverse strength, gas permeability and thermal expansion when specimens are extracted from AM sand moulds.

Sampling practice: Standard practice for extracting representative specimens from AM-built sand moulds, accounting for variability across a build.

Sources of variability: Identification of factors that cause uneven properties in AM moulds - e.g., location in a build space, layer-by-layer anisotropy, machine positioning and process fluctuations.

Requirements for specimen orientation and identification: Guidance (including annexes) on specimen identifier and orientation indexing to support reproducible testing and reporting.

Documentation and qualification workflows: Requirements for documenting purchasing specifications, verification of AM machine performance and reporting of test results to support supplier qualification and acceptance testing.

Use with existing standards: Intended to be applied in parallel with related test standards for conventionally manufactured sand moulds.

Applications

Foundry quality control: Validate that AM-produced sand moulds meet mechanical and thermal criteria for reliable casting performance (minimizing defects like poor surface finish, gas-related porosity or dimensional inaccuracy).

Supplier qualification & procurement: Create objective acceptance criteria for purchasing AM sand moulds based on documented test results.

AM machine qualification and process validation: Verify consistent machine performance across build cycles and locations within the build volume.

R&D and materials engineering: Compare feedstock, binder systems and process parameters to optimize mould properties for specific metal casting processes.
