Industrial Quality Control
In-house QC laboratories in cement, steel, textiles, polymers, paints and petrochemicals.
An in-house QC laboratory has a narrow, repeating test list and a strong incentive to keep it running. The purchase pattern reflects that: known reagents in known pack sizes on a predictable cycle, and instruments whose downtime is measured in production loss. Consumable continuity and a responsive spares position matter more here than breadth of catalogue.
Tests run here
- Chemical analysis of cement and clinker
- Ash, moisture and calorific value of fuels
- Tensile, hardness and impact testing of metals
- Viscosity, density and flash point of petroleum products
- Polymer melt flow index and thermal analysis
- Colour, gloss and adhesion of coatings
Governed by
- IS product specifications for the relevant commodity
- ASTM and ISO test methods
- ISO 9001 quality management systems
- BIS product certification (ISI mark) requirements
- filtration
- weighing
- spectroscopy
- physical-properties
