for
Regular/Premium
Valve Caps
I. The regular quality test of the Accu-Pressure valve caps, as brief as follows:
Purpose: Observe for air leakage or inaction.

  1. Destruction Test: After Accu-Pressure caps are locked and fixed on the test momentary inflation from 0 PSI to 70 PSI shall be performed. The action of this shall be executed.
  2. Functional Test: After Accu-Pressure caps are locked and fixed on the tes rod, momentary inflation from 0 to the specified pressure of the product (26 PSI – 40 PSI) shall be executed.
  3. Air-Tightness Test: Apply foam or soapy water on the entire gauge cap.
  4. Appearance Check: We reject products that are damaged and assembled in disorder.
  5. Sampling Test: The sampling rate for the above four items shall achieve 99.75% accuracy rate.
    ** The sampling ratio – 25:1
    ** Standard – Maximum 0.4% failure rate allowed.

  2. Design and Physical Characteristics:
    The tire safety gauge is found to protrude pass the sidewall of the tire on some designs.
  3. Salt Fog Corrosion Test (ASTM B117-85):
    The specimen was subjected to a 72-hour salt spray exposure in accordance with ASTM B117-97. The specimen was evaluated every 24 hours.
  4. High Temperature Test:
    The product in reference consists of highly insulated elements for the petrochemical heat generated in the tire during high-speed driving (40? C – 65? C) at the safety rate of 99.81%.
  5. Low Temperature Test:
    When used under 45? C, the product delivers the same performance as under normal temperature and environment at the safety rate of:
    45? C: 97.28%  and  30? C: 99.81%
  6. Road Test:
    Bumps: No effect
    Others such as dirt: No effect
    Water: 4 tiny drops of water on viewing dome after 2 hours under water.
