3. Construction, Shape and Dimensions
  The construction, shape and dimensions shall be as shown in the following tables. The permissible deviation of body thickness "a" and bonnet "a1" shall, as a rule, be within +15~-10%, but for 5K valves when the calculated value is below 1 mm, the deviation may be permitted up to 1mm.When specified by purchaser, valve seat of the disc may be finished with baking synthetic rubber.

4. Test and Inspection
  The swing check valves shall be subjected to the following items inspection accordance with JIS F7400.
  (1)Material inspection
  (2)Visual inspection
  (3)Dimensional inspection
  (4)Assembly inspection
  (5)Hydraulic inspection

The swing check valves shall be tested as follows:

  JIS F7372 C.I. Swing Check 5K
    (a)Watertight inspection for valve seat:
        Outlet side:0.76 MPa [7.7kgf/cm2] to 0.39MPa [4.0kgf/cm2]
    (b)Hydraulic inspection for body: 1.03MPa [10.5kgf/cm2]

  JIS F7373 C.I. Swing Check 10K
    (a)Watertight inspection for valve seat:
       Outlet side:1.51 MPa [15.4kgf/cm2] to 0.39MPa [4.0kgf/cm2]
    (b)Hydraulic inspection for body: 2.06MPa [21.0kgf/cm2]
