The Pfizer tester compresses tablet between a holding anvil and a piston connected to a force-reading gauge when its plier-like handles are gripped. [5] The Erweka tester tests a tablet placed on the lower anvil and a weight moving along a rail transmits pressure slowly to the tablet. [5]
In order to get a reliable reading the thickness of the test-piece should be at least 10 times the depth of the indentation. [15] Also, readings should be taken from a flat perpendicular surface, because convex surfaces give lower readings. A correction factor can be used if the hardness of a convex surface is to be measured. [16]
The long hundredweight is used as a measurement of vehicle weight in the Bailiwick of Guernsey. It was also previously used to indicate the maximum recommended carrying load of vans and trucks, such as the Ford Thames 5 and 7 cwt vans [ 8 ] and the 8, 15, 30 and 60 cwt Canadian Military Pattern trucks .

A professional astrologer explains how to read your birth chart to calculate all your planet and rising signs, astrological houses, compatibility, and more.
The rebound reading will be affected by the orientation of the hammer: when used oriented upward (for example, on the underside of a suspended slab), gravity will increase the rebound distance of the mass, and vice versa for a test conducted on a floor slab. Schmidt hammer measurements are on an arbitrary scale ranging from 10 to 100.
The Javan rhino (Rhinoceros sondaicus) once roamed across many countries in Southeast Asia. Around 2,000 years ago, they were still common in many parts of China. Around 12,000 years ago, they ...
