Overview

EN ISO 4489:2019 - Hardmetals: Sampling and testing specifies standardized procedures for sampling and testing hardmetals (cemented carbides) to determine their physical and mechanical characteristics. Prepared by ISO/TC 119 (Powder metallurgy) and adopted by CEN, this international standard defines practical rules for taking test samples from lots and refers to established ISO test methods for density, hardness and other key properties. The standard is intended to support consistent quality control, product acceptance and comparative testing across suppliers and laboratories.

Key topics and requirements

• Scope and purpose
  • Procedures for sampling hardmetal parts (recognizing a wide range of sizes and applications).
  • Emphasis that many determinations are time-consuming or destructive, so sampling must be practical and economical.
  • For grade confirmation, one test sample unit is often sufficient.
• Sampling principles
  • Definitions: lot (quantity of presumably uniform sintered parts) and test sample.
  • Sampling approach tailored to production control and small-order practices.
• Mandatory tests (referenced standards)
  • Density - ISO 3369.
  • Hardness (HRA) - ISO 3738‑1 and ISO 3738‑2 (Rockwell A scale).
  • Hardness (HV) - ISO 6507 series (Parts 1–4) for Vickers hardness testing, verification and calibration.
• Optional / special-case tests
  • Transverse rupture strength - ISO 3327.
  • Microstructure - ISO 4499‑1, ISO 4499‑2, ISO 4499‑3.
  • Porosity, carbon defects and eta‑phase content - ISO 4499‑4.
  • Fracture toughness (Palmqvist) - ISO 28079.
  • Magnetic characteristic analysis (coercivity, saturation) is used in practice but is device-specific (ISO 3326 withdrawn).
• Test reporting
  • Recognizes that small orders and stock items often cannot retain lot identity, so a test report may not always accompany individual orders.

Applications and users

• Who uses EN ISO 4489:2019
  • Hardmetal (cemented carbide) manufacturers and suppliers.
  • Quality control and metallurgical testing laboratories.
  • Procurement specialists and OEMs specifying acceptance criteria.
  • R&D teams developing powders, grades and sintering processes.
• Practical benefits
  • Harmonizes sampling and testing practice for consistent hardness, density, microstructure and mechanical property assessment.
  • Supports product acceptance, conformity assessment and cross-lab comparability.
  • Helps reduce unnecessary destructive testing while ensuring representative results.

Related standards

• ISO 3369, ISO 3738‑1/2, ISO 6507‑1/2/3/4, ISO 3327, ISO 4499‑1/2/3/4, ISO 28079 (as referenced by EN ISO 4489:2019).
