Dec 14, 2020 · Divide by Conversion Factor. Divide the ppm hardness value by 17.1, the conversion factor for ppm to gpg. The result is the water hardness eed in grains per gallon. For example, say you have a water hardness value of 180 ppm. Work out. Shore D Hardness Test (Durometer Scale) - Hardness of Shore D Hardness is a standardized test consisting in measuring the depth of penetration of a specific indenter. Test methods used to measure Shore D Hardness are ASTM D2240 and ISO 868. The hardness value is determined by the penetration of the Durometer indenter foot into the sample. Shore Hardness measures are dimensionless.
Apr 27, 2011 · Electrum is depending on its composition very slightly more durable than either gold or silver (one of the attractions of making coins out of it), so I'd give it a hardness of about 5. I'd also increase hardness of Copper and Bronze by 1 per inch over 1 to a maximum of +10 or so.
