Quality Framework · Sita Ram Defence Products
The grade is the contract
Four grades. One promise. Zero ambiguity.
Across the Raj Parivar Group, every product is engineered to one of four declared tolerance grades. Defence variants carry an additional D identifier. The grade is not aspirational — it is an enforceable buyer-facing commitment, backed by inspection records and traceability.
The four defence grades
Pick the grade that fits the mission. We’ll hold it.
Each grade carries a specific tolerance envelope, documentation depth, and inspection cadence. We price transparently against the grade — so you’re never paying for more tolerance than your programme needs, or less than it deserves.

Quality process
Six stations, one unbroken chain of custody.
From incoming material to final release, every part passes through six discrete quality stations. Each station has a defined owner, a defined output, and a record that survives the job.
QS.01
Incoming inspection
Raw material is verified against mill test certificates before being released to the shop floor. Non-conforming lots are quarantined.
- MTC verification
- Dimension & identity check
- Quarantine for non-conforming
QS.02
First-article inspection
Every new part number or revision requires a formal first-article inspection before series production is authorised.
- Dimension, form, finish
- Material cross-check
- Buyer sign-off on request
QS.03
In-process controls
Patrol inspection and SPC on critical characteristics ensure drift is caught before it reaches the buyer.
- Patrol frequency per spec
- SPC on critical dims
- Real-time operator feedback
QS.04
Final inspection & release
A final inspection against the drawing and grade happens in a dedicated, lit and calibrated space — not on the production line.
- Full dimensional verification
- Visual & surface QA
- Record-backed release
QS.05
Calibration
Every instrument used in inspection carries a valid calibration certificate. Out-of-cal instruments are removed from the floor.
- Annual calibration cycle
- Traceable to national standards
- Instrument-level history
QS.06
Non-conformance handling
A formal NCR process with containment, root-cause analysis and corrective action, tracked to closure with the buyer in the loop.
- 8D-style root-cause
- Containment & rework protocol
- Buyer-notified closure
