Hyundai ES03875-01 Engineering Specification Test and Development Procedure

The “ Hyundai ES03875-01 Engineering Specification Test and Development Procedure” standard, developed by Hyundai Motor Company , describes the following test procedures:

• F/F DR opening and closing durability test
• CATCH & CABLE ASSY opening and closing endurance test
• F/F DR downward hardness test
• F/F DR opening direction hardness test
• RELEASE HANDLE hardness test
• CATCH & CABLE low temperature adverse condition test

F/F DR opening and closing durability test

Environmental condition: Behavior at room temperature (23 degrees plus/minus 5 degrees).

Test condition:

• The working power should be measured after opening and closing are repeated 10 times.
• It is assembled with the minimum TORQUE specified when mounting the H/W.

In the tests, an opening and closing endurance tester is used.

Requirements:

• F/F DR closing force should be 30N or less, there should be no interference in the relevant parts, there should be no permanent deformation (For PUSH-OPEN type, the operating force should be 30 plus/minus 3N.)
• F/F DR POP UP amount should be 25mm or more (For PUSH-OPEN type, it should be 10mm or more)
• For F/F DR, there should be no interference in the relevant part.
• There should be no damage to the hinge or permanent deformation that could cause loosening and functional failure of the PIN.
• There should be no damage or deformation to F/F DR and CATCH when closed in bad condition.
• After the PUSH-OPEN type F/F DR test is completed, no foreign matter should leak into the PUSH OPENER.
• For PUSH-OPEN type, the locked door should not be opened with an opening force less than 150N.

CATCH & CABLE ASSY opening and closing endurance test

Environmental condition: Behavior at room temperature (23 degrees plus/minus 5 degrees).

Test condition:

• The working power should be measured after opening and closing are repeated 10 times.
• It is assembled with the minimum TORQUE specified when mounting the H/W.

In the tests, an opening and closing endurance tester is used.

Requirements:

• The initial working EFFORT of RELEASE HDL should be 30N or less (less than 4.000N after 49 times of endurance test)
• There should be no deformation/damage that could cause cable breakage and functional malfunction.

F/F DR downward hardness test

Environmental condition: Behavior at room temperature (23 degrees plus/minus 5 degrees).

Test condition:

• The working power should be measured after opening and closing are repeated 10 times.
• It is assembled with the minimum TORQUE specified when mounting the H/W.

In the tests, an opening and closing endurance tester is used.

Requirements:

• There should be no peeling of paint due to interaction with the body.
• After removing the load application, the change amount of RELEASE HDL EFFORT and closing force should be within 10 percent, and the permanent change amount of clearance/step difference/relaxation amount should be within 1,0 mm.
• There should be no hinge part noise and deformation.

F/F DR opening direction hardness test

Environmental condition: Behavior at room temperature (23 degrees plus/minus 5 degrees).

Test condition:

• The working power should be measured after opening and closing are repeated 10 times.
• It is assembled with the minimum TORQUE specified when mounting the H/W.

In the tests, an opening and closing endurance tester is used.

Requirements:

• When D5N load is applied, there should be no paint peeling due to interaction with the body.
• After the load application is removed, the change amount of RELEASE HDL EFFORT and closing force should be within 10 percent, and the permanent change amount of clearance/pitch difference should be within 1,0 mm.
• There should be no noise or deformation of the hinge part.
• The breaking strength of the holding area and CAP suspension area should be more than 150N.

RELEASE HANDLE hardness test

Test condition:

• It is assembled with the minimum TORQUE specified when mounting the H/W.

In the tests, the RELEASE HANDLE mounting apparatus is used.

Requirements:

• It should function normally without damage, deformation and separation.

CATCH & CABLE low temperature adverse condition test

Environmental condition: Minus 30 degrees (minus 10 degrees for India/Central North America), soaking for 8 hours.

In the tests, a low temperature environment chamber (minus 30 degrees) is used.

Requirements:

• Upon visual inspection, there should be no freezing due to water ingress.
• After checking the process there should be no functional issues.
