适用范围：This standard lays down recommendations for design of scales and associated indexes for quantitative instruments to enable rapid reading to aresolution of about 1 to 2 percent of the scale range when read from a given maximum distance. These recommendations are applicable only to single scale instruments having dials with full circle, part circle or straight scales. These recommendations are not applicable to trans-illuminated dials nor to moving-scale with fixed index in instruments.
