Swimming goggles sealing tester

The Swimming Goggles Sealing Tester is a specialized test instrument designed to evaluate the watertightness and sealing performance of swimming goggles in accordance with ISO 18527-3.

The equipment provides a controlled and objective method to assess the resistance of goggle seals against the ingress of liquids, gases, and vapors. It is suitable for laboratory testing, production-line quality control, and product development.

The tester utilizes a standardized test head and controlled vacuum or pressure system to detect leakage through pressure decay over a defined test period, ensuring compliance with international safety and performance standards.

Application

(1) Swimming Goggles: Adult swimming goggles, children’s swimming goggles, competition goggles.

(2) Protective Sports Goggles: Training goggles, recreational water-sport goggles.

(3) Medical & Protective Goggles: Splash-protection goggles, laboratory eye protection with sealing requirements.

(4) Industrial Protective Eyewear: Chemical splash goggles, dust-tight safety goggles.

(5) R&D and Product Development: Development and optimization of goggle frame designs, sealing structures, and cushion materials.

(6) Production Quality Control: In-line or batch testing to ensure consistent sealing integrity during manufacturing.

(7) Certification & Compliance Testing: Verification of product conformity with ISO and EN standards prior to market release.
