RIDSDALE-DIETERTSAND SPECIFIC SURFACE TESTER (cont’d)CALIBRATION PROCEDUREThe chart supplied with the equipment is only correct for silica sands with a relative density of 2.65.The small deviations in relative density which occur in natural foundry-sands can be ignored.The equipment can be used for other sands such as zircon sands and olivine sands, but avolumetrically equivalent quantity of sand must be used.The sample weight for a volumetrically equivalent sample of a sand other than silica is determinedfrom the following expression :-W x = W sD x___D swhere W x is the weight of the sample of sand to be tested;W s is the weight of silica sand normally used (50 g);D x is the relative density of the sand to be tested;andD s is the relative density of silica sand (2.65).For example, determining the specific surface area of zircon sand (relative density 4.6), the :Sample weight to be used = 50 g x 4.6 ÷ 2.65 = 86.8 g. This correspondsvolumetrically to 50 g of silica sand and hence the same conversion chart as for silica sands may beused.21
