Chemical Methods. Sherds were prepared for analysis by removing surface glazing and designs with a fine-grit silicon carbide abrasive paper. 

The equation was found to be in reasonable accord with the results from a series of tests using TNT, RDX, and HMX in various admixtures of fine grits. Whether the equation can be applied to primary explosives is not known. 

The discharge probe is cleaned after each test with fine grit emery paper and the sample holder is cleaned after each test series. 

The key to fast electrode equilibration with the skin is removing or abrogating the skin comeum. This is usually performed by skin abrasion. Fine-grit abrasive materials are sometimes incorporated into conunercial electric coupling creams so that outer layers of dead skin will be removed on...

Stress relieving heat treatments of the runner and discs must be specified at stages during manufacture. It is interesting to note that even the fine grit blasting operation to prepare the taper-land disc blanks for coating, can, unless carefully controlled, result in unacceptable distortion.
