d) the balance (range 1000g, minimum scale 0.01g).

6.2.2.2 clip full size 50cm long specimen 3, oven drying to constant weight, were weighed its dry mass. Without weighing chamber conditions when the sample should be removed from the oven, placed above the cooling 30min weighed again within the dryer.

6.2.2.3 according to equation (1) calculate the mass of the sample deviation rate calculated results are accurate to one decimal place.

sigma =

m0-2m1 (1 R)

100% (1)

Where.

sigma --- quality deviation rate,%;

m0 --- quality specifications in meters per gram (g/m);

m1 --- dried sample mass, in grams (g);

R --- moisture regain,%.

The average 6.2.2.4 Take three samples test results as the final result.

6.2.3 Billiards bursting strength test
