Automotive Lamp Air Tightness Tester
Category：Tightness Tester
Introduction
The Automotive Lamp Air Tightness Tester is designed to evaluate the sealing performance of vehicle lighting systems. It uses a positive pressure method to detect leakage in lamp housings, ensuring compliance with IP67/IP68 waterproof and IP6X dustproof requirements. The system provides high-precision leak detection (≤0.1 ml/min), enabling rapid identification of defects such as housing cracks and seal aging.
Application
(1) Air tightness testing of automotive lamps including headlights, tail lights, and turn signals.
(2) Leak detection for lamp housings, seals, and connectors.
(3) Verification of waterproof (IP67/IP68) and dustproof (IP6X) performance.
(4) Quality control in automotive lighting production lines.
(5) Suitable for OEMs, suppliers, and automotive testing laboratories.
Standards
(1) IEC 60529 – Degrees of protection (IP Code)
(2) ISO 20653 – Road vehicles – Degrees of protection (IP code)
(3) GB/T 4208 – Enclosure protection classification (reference)
