Inspection（Reference：JIS L1913）

   *1 Weight        ：Sample Size：4m×1m 

Obtain one sheet of sample sheet (product width x 100cm). Use a balance and measure  (Minimum scale 0.01g) the weight of unit area.

  *2 Air Permeability：JIS L1913  Frazir Type Tester 

 Obtain 21 sheets of sample sheet (about 10cm x 10cm) to the width direction in fixed intervals. Use Frazir type tester, measure the air permeability at 125Pa and take the ave rage.

   *3 Tensile Strength：JIS L 1913 Cut Strip Method  

                    Sample Size(Width×Length)：50mm×300mm  

                    Clamping Distance：200mm， Rate of Stretching：100±10mm/min       Obtain 3 sheets of sample (50mm x 300mm) to the width direction in fixed intervals.  

    Use tensile tester (TENSILON), measure the tensile strength and the elongation with the  interval of 200mm and the speed pull 100mm/min and take the average.

*4 Thickness       ：Sample Size：4m×1m 

Obtain 21 sheets of sample sheet (about X:100mm x Y:200mm) to the width direction in fixed intervals and measure 5 points of each sample and take the average.
