Spray foam material is packaged, sold and shipped on the basis of weight. Therefore, in order to figure the volume of a product packaged in the drum, transforming the weight of the item within the drum into gallons is required. To do so, the particular gravity or weight per gallon of product is needed info. There is likely to be a distinction in between makers, so verify with the item supplier to offer this info or if a scale is readily available, weigh the container initially.
Specific Gravity and per gallon weight of the liquid for some manufacturers are provided on the SDS or product information sheet (previously MSDS).
When the specific gravity is known, increase the specific gravity by 8.33 (the weight of one gallon of water). This will supply the weight of one gallon of the product.
Utilize one of the two following formulas to figure just how much volume in gallons remains in the container:
INTERNET WEIGHT OF LIQUID/ (SPECIFIC GRAVITY * 8.33)= VOLUME (IN GALLONS).
NET WEIGHT OF LIQUID/ WEIGHT PER GALLON= VOLUME (IN GALLONS).
Numerous makers have actually made the required computations and have changed the drums appropriately while others have not. So, a little due diligence on our part will offer the needed information to determine how the products are packaged and help when confirming stroke counter limitations.
