Testing & Quality Assurance

Every Bus Earns Its Roadworthiness

Every body undergoes rigorous structural, leakage, electrical and roadworthiness testing before leaving the plant. We comply with AIS, CMVR and OEM standards.

Structural Tests

Body strength, joint integrity and dimensional verification.

Shower / Leakage Test

Full-body shower test for water-tightness.

Electrical Tests

Harness continuity, insulation and HV battery system checks.

Roadworthiness

On-road verification before customer dispatch.
