Overview
EN ISO 16282:2008 (ISO 16282:2007) specifies a standardized laboratory method to determine the abrasion resistance of dense shaped refractory products at ambient temperature. Intended primarily for shaped refractories (and applicable to unshaped materials), the test provides a quantitative indication of a material’s suitability for service in abrasive or erosive conditions. This European adoption by CEN supersedes EN 993‑20:2004 and aligns with international practice for refractory quality assessment.
Key topics and technical requirements
- Test principle: measure the volume of material abraded from a flat face of a test piece by blasting a controlled mass of abrasive through a nozzle onto the surface.
- Abrasive and feed: 1 000 g of size‑graded silicon carbide (FEPA P36 equivalent) is fed to the blast assembly in (450 ± 15) s; sieve distribution and pre‑treatment are specified.
- Blast conditions: compressed air at ~450 kPa drives the abrasive through a venturi blast assembly or blast gun; secondary air and feed mechanism control are required.
- Geometry and positioning: the nozzle‑to‑specimen distance is (203 ± 1) mm; a glass nozzle and stabilizing sleeve arrangement is specified to ensure repeatability.
- Specimens: typical specimen sizes are 114 × 114 × 64 mm (standard) and 100 × 100 × 25 mm for highly abrasion‑resistant materials; one flat original surface is used.
- Measurements and calculations: specimens are dried to constant mass, weighed (±0.1 g), and volume loss is calculated from mass loss and density (bulk density/apparent porosity per ISO 5017 where relevant).
- Ancillary requirements: manometer and vacuum gauges for chamber and feed checks, balance, callipers, and ISO‑compliant sieves (ISO 565).
- Documentation: the standard includes precision guidance and a required test report format.
Applications and users
Who uses EN ISO 16282:2008:
- Refractory manufacturers for quality control, batch acceptance and product development.
- Materials engineers and R&D teams comparing abrasion performance of formulations.
- Industrial end‑users (steel, cement, glass, power plants, foundries) for service selection and lifecycle assessment of linings exposed to abrasive solids or erosive flows.
- Third‑party testing laboratories performing standardized comparative tests for procurement specifications.
Practical uses:
- Rank and select refractory grades for abrasive/erosive service.
- Verify supplier claims and support warranty or acceptance testing.
- Guide formulation changes to improve wear life.
