• Place the specimen in boiling water for 5 hours. Then take it out, wipe the surface with a cloth, and weigh it. Let this weight be W4. Then, Percentage absorption by weight = (W2 - W1) / W1 x 100 ………. (1) Percentage absorption by volume = (W2 - W1) / (W2 - W3) x 100 ………. (2) Percentage porosity by volume = (W4 - W1) / (W2 - W3) x 100 ………. (3),For determining the hardness of a stone, the test is carried out as follows: A cylinder of diameter 25mm and height 25mm is taken out from the sample of stone. It is weighed. The sample is placed in Dorry's testing machine and it is subjected to a pressure of 1250 gm. Annular steel disc machine is then rotated at a speed of 28 rpm.

An x-ray uses electromagnetic radiation to create black-and-white images of the inside of your body. Your health provider may order an x-ray if they suspect gas buildup, calcified gallstones or porcelain gallbladder concerns. You could need other tests along with an x-ray. The procedure for getting an x-ray can vary,Smith Test: Break off the freshly quarried stone chippings to about the size of a rupee coin and put them in a glass of clean water, one-third full. If the water becomes slightly cloudy, the stone is good and durable. If water becomes dirty, it indicates that the stone contains too much of earthy and mineral matter.

Refractive Index Testing: the General Procedure. Place a bright light source behind the refractometer and direct it into the light window. Place a tiny drop of RI fluid on the hemicylinder. Put the gem table-down in the RI liquid (as shown in the illustration) and center it on the hemicylinder. Look through the lens,Procedure : The selected and weighed sample is placed in distilled water in a glass vessel at room temperature (20 degree C-30 degree C ) for a period of 24 hours.

Tests were devised using an Accelerated Polishing Machine and a friction measuring device, a Skid- Tester, to determine a Polished Stone Value. These developments have resulted in a simple and inexpensive procedure to determine in advance of a road being built what its resistance to skidding will be. Our Accelerated Polishing Machine was first ,The Standard Test Procedures detailed in this document are mandatory for the Standard Laboratory Test forms have been produced for the tests detailed in similar behaviour e g crushed crushed rock pulverised fuel ash or These masses include some allowance for drying wastage and rejection of stones .
