ISO 16282:2007

Overview

ISO 16282:2007 specifies a standardized test method for determining resistance to abrasion of dense shaped refractory products at ambient temperature. Primarily intended for shaped refractories (and applicable to unshaped materials), the method gives a reproducible indication of a material’s suitability for service under abrasive or erosive conditions by measuring the volume of material removed when blasted with a size-graded abrasive.

Key topics and technical requirements

• Test principle: measure volume loss from a flat test surface after blasting with 1 000 g of silicon carbide abrasive propelled by compressed air.
• Abrasive: silicon carbide with sieve distribution specified (corresponds to FEPA P36); remove material retained on 850 µm sieve and passing 300 µm sieve.
• Apparatus:
  • Venturi blast assembly or blast gun with specified air-delivery nozzle dimensions (inlet 2.84–2.92 mm; outlet 2.36–2.44 mm).
  • Glass nozzle tube (115 mm long) inserted through a steel sleeve; a new glass tube for each determination.
  • Sealed test chamber with exhaust and manometer; blast distance (203 ± 1) mm from nozzle tip to test surface.
  • Feed mechanism delivering (1 000 ± 5) g abrasive in (450 ± 15) s.
• Operating conditions:
  • Compressed air pressure to blast assembly (450 ± 7) kPa.
  • Test chamber pressure controlled to 310 Pa (32 mm water).
  • Vacuum check at abrasive entry port: minimum 375 mmHg indicated on vacuum gauge.
• Test pieces:
  • Typical shaped specimens: 114 × 114 × 64 mm (or 100 × 100 × 25 mm for very abrasion-resistant materials).
  • Dry at (110 ± 5) °C to constant mass before testing.
• Calculation:
  • Determine bulk density (ISO 5017 or via mass/volume) and compute volume loss A = mass loss / bulk density.
• Reporting: comprehensive test report requirements (sample ID, dimensions, preparation, individual results and mean, deviations, anomalies, date).

Applications and users

ISO 16282:2007 is used to:

• Compare abrasion resistance of refractory bricks, shapes and unshaped refractories.
• Support material selection and quality control for linings exposed to mechanical wear.
• Provide test data for specifications, procurement and R&D.

Typical users include refractory manufacturers, materials laboratories, quality assurance engineers, R&D teams, and procurement/specification writers in industries where abrasive wear is a concern (e.g., high-temperature process linings).

Related standards

• ISO 5017 - determination of bulk density and porosity (referenced for bulk density calculation).
• EN 993-20 - this ISO standard is based on and technically identical to that European standard.
