Quality Assurance
Tested like a reagent. Priced like a mineral.
ISO 9001:2015 certified quality management with an in-house laboratory — every dispatch carries a Certificate of Analysis.
ISO 9001:2015
Certified quality management system covering the full chain — mining, processing, laboratory and dispatch. Documented procedures, calibrated instruments and audited records.
MSME Registered
Registered under the Micro, Small & Medium Enterprises framework — formal, compliant and eligible for institutional procurement programmes.
In-House Laboratory
Sieve shakers, drying ovens, muffle furnace and microscopy on site. Samples retained from every lot for traceability and dispute resolution.
What we measure, and how often.
| Test | Method | Frequency |
|---|---|---|
| Sieve Analysis | Multi-deck gradation testing to confirm AFS 40–100 distribution on every production lot. | Every batch |
| Chemical Assay (XRF) | SiO₂, Fe₂O₃, Al₂O₃, TiO₂ and alkali verification against published grade windows. | Every batch |
| Loss on Ignition | Organic and volatile content measured at 1000°C to protect binder chemistry in foundry use. | Every batch |
| Moisture Content | Post-dryer verification to ≤ 0.10% before bagging, preventing caking and weight disputes. | Every batch |
| Clay & Silt | De-sliming efficiency check ensuring turbidity-free filter and glass feed. | Per shift |
| Grain Morphology | Microscopic angularity review to maintain sub-angular shape specifications. | Weekly audit |
Certificate of Analysis
Every dispatch — bagged or bulk — ships with a lot-specific CoA covering chemistry, gradation, moisture and LOI. Third-party NABL testing can be arranged on request.
