Technical parameters

    1. Outer tube: inner Φ150mm, high 150mm

    2. Inner tube: outer 150mm, high 149mm

    3. Inner tube weight: 8.8kg

 

 Test procedure

1. Put 100g sample evenly into the outer cylinder of the measuring cylinder. Put the inner tube into the outer tube to make the bottom gently connect with cotton, do not shock, do not press it with hand. After 5 minutes, measure equidistant three point of the cylinder periphery, with slide calliper rule measure the height difference of the inner and outer tube to the nearest 0.1 mm. The arithmetic mean of three points is the thickness of the sample.

    2. The result of the calculation: density of the sample is calculated according to the formula (9). Results reserves integer.

                     5.66 X  10

   P=               h          …………(9)

Where:

     p ......... granular cotton or raw cotton density, in units of: kg/m3  

3. 5.66 x 10 m3 - mass of the sample divided by the bottom area of the measuring cylinder incomes constant, in units of gram per square meter (g / m2);

             H -- sample thickness in millimeters (mm).
