一、概述及适用范围: 油石量块和金属量块相比较,有其独特的优点,使用和保管都很方便。因此深受各厂矿企事业单位计量人员的喜爱,被广泛应用,在计量工作中起到了一定的作用。经过十多年对油石量块的检测研究,发现油石量块在（20±8）℃温度范围内,尺寸比较稳定,线膨胀系数和金属量块基本相同。为此,特编制油量块测试方法。本测试方法适用于检定测量范围至 500mm的游标卡尺以及检定0-100（mm）的壹级千分尺专用油石量块。二、环境条件:
First, an overview and scope of application: Whetstone block and metal block compared with its unique advantages, use and storage are very convenient. Therefore by all factories, mines and institutions of measurement personnel favorite, is widely used in the measurement work has played a certain role. After more than a decade of oilstone block detection study, found that the stone block in the (20 ± 8) ℃ temperature range, the size is relatively stable, linear expansion coefficient and the metal mass is basically the same. To this end, special preparation of oil block test method. This test method is suitable for testing vernier caliper measuring range to 500mm and testing 0-100 (mm) for the first micrometer dedicated stone block. Second, the environmental conditions:
