Testing Centre
A full in-house testing laboratory with professional equipment and dedicated staff — the data stays in the plant, and so does the responsibility.
Testing capability list
We own professional burst, tensile, airtightness and current testing equipment and staff, and test data can be supplied with the goods.
Burst testing
Verifies the ultimate pressure capacity of hose assemblies at the specified pressure, confirming the safety margin meets standards and customer requirements.
Tensile testing
Tests the pull-off resistance where the hose meets the fitting, assessing crimping process and assembly reliability.
Airtightness testing
Checks assembly sealing performance at the specified pressure, identifying micro-leaks and preventing leak risks after installation.
Current testing
For electrically heated urea lines, tests heating circuit continuity and resistance to confirm low-temperature heating works.
Dimensional & visual inspection
Checks inner/outer diameter, wall thickness, length, bend angle and markings, plus hose appearance and rubber surface quality.
Temperature & media resistance
High-temperature, low-temperature, oil and media resistance tests are performed as required to assess long-term reliability.
How testing feeds back into R&D
The laboratory is not only for releasing products but for validating design. Every burst curve, tensile value and leak reading flows back into formulations and process parameters, closing the R&D–testing loop.
- Design validationValidating structural strength and sealing design at prototype stage
- Process confirmationLocking the parameter windows for vulcanising, crimping and over-moulding
- Volume monitoringSampling data monitors process stability and trends
- Customer deliveryTest reports and batch records supplied with the goods on request
Standards & certification support
Products follow national and industry standards such as GB 16897-2022, and we support third-party testing and OEM approval validation as required by customers.
National standards
Brake hoses follow GB 16897-2022; nylon tube assemblies follow the relevant QC/T standards and OEM corporate standards.
Compulsory certification
Automotive rubber air-brake and nylon air-brake hose assemblies hold CQC compulsory product certification.
System support
The IATF 16949 quality system keeps processes under control; PPAP documentation and audit support are available on request.
