Overview
ISO 4489:2019 is an international standard developed by the International Organization for Standardization (ISO) that specifies the procedures for sampling and testing hardmetals. Hardmetals, also known as cemented carbides, are widely used in industrial applications due to their exceptional physical and mechanical properties. This standard ensures consistency and reliability in the determination of these critical characteristics by defining uniform methods for sampling, testing, and reporting results.
The 2019 edition of ISO 4489 replaces the original 1978 version and incorporates updated references and testing procedures aligned with contemporary international standards. It is intended for manufacturers, quality control laboratories, and end-users who require standardized evaluation methods for hardmetal products.
Key Topics
Sampling Procedures
ISO 4489:2019 outlines specific sampling methods to obtain representative test specimens from lots of hardmetal pieces. The standard recognizes practical constraints like the range of sizes and quantities and the destructive nature of some tests. Typically, a single sample may suffice to confirm material grade, particularly during production control.Testing Methods
The standard mandates compliance with various established ISO test methods to assess the physical and mechanical properties of hardmetals, including:- Magnetic properties (coercivity and magnetic saturation): While specific ISO methods for these tests are no longer active, general guidance is noted.
- Density measurement: According to ISO 3369.
- Hardness testing: Both Rockwell Hardness A-scale (HRA) and Vickers Hardness (HV) methods as per ISO 3738-1/2 and ISO 6507 series respectively.
Additionally, special-case tests, such as flexural strength (ISO 3327), microstructure characterization (ISO 4499 series), porosity and carbon defects analysis, and Palmqvist toughness (ISO 28079), are referenced for more detailed assessments.
Reporting
Due to the frequent small batch sizes and stock-based ordering in hardmetals, ISO 4489:2019 notes that lot identification can be challenging and therefore does not mandate full test reports for every order. However, standard reports should include relevant test data when provided.
Applications
ISO 4489:2019 serves as a crucial reference for various stakeholders in the hardmetal supply chain:
- Manufacturers rely on this standard for consistent sampling and testing during production to guarantee material conformity and quality.
- Quality Control Laboratories utilize ISO 4489 to perform standardized tests, ensuring repeatability and comparability of results.
- End-Users and Buyers benefit from the assurance that hardmetals meet internationally recognized specifications, improving trust and enabling informed purchasing decisions.
- Research and Development teams use these procedures to validate new hardmetal formulations and optimize their physical-mechanical performance.
The standard supports industries such as tooling, machining, wear parts manufacturing, and any application requiring reliable, high-performance hardmetal components.
Related Standards
ISO 4489:2019 references several key standards that complement its scope and testing methods for hardmetals:
- ISO 3369 – Determination of density for sintered metals and hardmetals.
- ISO 3738-1 and ISO 3738-2 – Rockwell Hardness testing methods for hardmetals.
- ISO 6507-1 to ISO 6507-4 – Vickers hardness testing, machine calibration, and hardness tables.
- ISO 3327 – Flexural strength testing for hardmetals.
- ISO 4499-1 through ISO 4499-4 – Metallographic examination of hardmetal microstructures, grain size, porosity, and defect analysis.
- ISO 28079 – Palmqvist toughness testing method, which measures the hardness-related fracture toughness.
These complementary standards ensure comprehensive evaluation and facilitate accurate characterization of hardmetal properties within diverse industrial contexts.
By adhering to ISO 4489:2019, stakeholders in the hardmetal industry can achieve reliable, repeatable sampling and testing results, facilitating quality assurance, product development, and compliance with international best practices. This standard plays a vital role in supporting the durability and performance excellence expected from hardmetal components across numerous engineering applications.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
