Quality Assurance

Inspros has adopted a holistic view to quality – an approach which combines

• Strict control on input materials.
• Vendor audits and compliance with specifications.
• Well practised QA plans during in-house manufacturing.
• Stage quality checks and tests.
• Empowered workmanship.
• Prolific usage of assembly gauges, fixtures & Poka-yoke tools.
• Extensive product testing.

Processes and test methods at Inspros have been designed to uphold the Company’s commitment to ISO 9001 & maintain high standards of health & safety in the manufacturing facility & environment.

Besides subjecting the products to rigorous type-testing as may be stipulated in relevant national or international standards, at recognized independent test laboratories, facilities for carrying out various routine or special tests exist in-house too, viz:

• Force - stroke analysis of a solenoid.
• Endurance testing of solenoids.
• Temperature rise test.
• Hi-pot and tan-delta measurement of stator coils.
• Burn-in test of coils.
• Mechanical load testing of bushings.
• Leakage testing of bushings.
• Endurance testing of various traction controlgear devices.
• Milli-volt drop test of traction controlgear.
• Surge comparison testing, inter-turn short testing, hi-pot testing, resistance & inductance    measurement.
• Hardness testing.
• Conductivity measurement.
• Electroplating thickness testing for ferrous & non-ferrous coatings.
