Specific gravity of a material can be calculated by following equation: The testing method of SG for plastic systems is ASTM D792 and ISO 1183. SG of plastic is less compared to other materials influence its price; thus all plastic materials are sold on cost per weight basis. The specimen is weighed first in air (Weight A), and then weighed when immersed in distilled water at 23C (Weight B). Polystyrene 1.05 Physicists use 39.2 F (4 C) as the standard, but engineers ordinarily use 60 F.

First, we have to know that the formula of density is: As formula shown, density is total mass of the object divided by total volume of object, which means: 1 gram per cubic centimetre or 1 kilogram per cubic metre.Density of water is1 gram per cubic centimeter (1 g/cm3), but actually, the exact density of water is not really 1 g/cm3, but rather a bit less (very, very little less) than 1, so we can say thatgenerally the weight and volume of water is the same.What's the meaning of "Specific Gravity"?Specific Gravity means specific value of an object undernormal temperature and pressure. 0000158889 00000 n

When the plastic that expanded beyond the container is removed we now find that the remaining cube of heated plastic inside the container weighs only 0.933 grams. Machine Design Apps Thanks to its versatile properties, such as lightness, durability, and easiness of processability, PVC is now replacing traditional building materials like wood, metal, concrete, rubber, ceramics, etc. The solid wood density may be determined using the green volume, : The units cancel out in the ratio. +hSm)/BNy-G:ipb4m(5i9 18N 2Y9 E7q!#5qnc"w2T.Cz(k4l@Ar$.n(*piE1uh%UF?x]*t4\J4j1i,/7Mq$``'> These applications will - due to browser restrictions - send data between your browser and our server.
