ISO 9001 (TS-EN) since 1996 — the management discipline that makes consistent product quality achievable across an integrated mine-to-brick operation.
KONREF has held the TS-EN ISO 9001 quality management certificate continuously since 1996 — almost three decades. The value of that certificate lies not in the paper itself but in the management discipline it requires: documented processes, defined responsibilities, systematic measurement, and structured improvement cycles.
For a vertically integrated operation — where quality problems can originate anywhere from mine geology to pressing parameters to kiln temperature — this discipline has to span the full chain, not just the factory floor.
Grade specifications defined for each product, with quality plans that identify critical control points from raw material intake through to finished product dispatch.
Fully computerised production lines with continuous parameter monitoring. Pressing pressure, kiln temperature profile, and mix composition are recorded and reviewed for every production run.
Physical testing (bulk density, porosity, CCS, MOR) and chemical analysis (XRF) on every product line. The 2015 laboratory modernisation expanded our testing capability significantly.
Every production batch is traceable from the finished product back to the raw material lot — DBM production date, pressing parameters, firing cycle and quality test results.
Structured non-conformance reporting, root cause analysis and corrective action for all quality deviations — at production and on receipt of customer complaints.
Annual management review of quality system performance — including quality metrics, customer satisfaction, audit findings and improvement opportunities.
