If required, provide a shim of unfaced fiberglass(approximate 8.01 kg/m3) under the specimen that is cut to fit holder and center drilled to align with specimen. Carefully cut excessmaterial extending above the to
42、p edge of the specimen holder. A reciprocating electric knife or saw has been found suitable. Takecare that the center drilled hole is free of debris and if the shim pad is used, that the hole is aligned through specimen and pad.6.5.7.5 Weigh specimen and specimen holder, subtract weight of empty sp
