This Standard specifies micrometer for external measurements, bar-shaped micrometer for internal measurements, micrometer for span measurements of teeth, and micrometer head (hereafter referred to as micrometer, unless otherwise specified) equipped with analogue...
Work Instruction for the internal calibration of 0 - 1 Inch and 0 - 25mm External Micrometers. To be used in the absence of a manufacturers calibration instruction.
Heads for assembly with measuring or machine tools. Three types, thimble diameters below 1 in, 1 in and below 2 in, 2 in and over; measuring ranges ½ in, 1 in, 13 mm, 25 mm. Material, micrometer screw, spindle, thimble and barrel adjustments, measuring faces and graduations, dimensions and...
5.1 These test methods shall be used where precise dimensions are necessary for the calculation of properties expressed in physical units. They are not intended to replace practical thickness measurements based on commercial portable tools, nor is it implied that thickness measurements made by the...
1. SCOPE The material defined by this specification is a woven screen constructed in a plain square weave using polyester monofilament thread with a nominal 120 micrometer mesh opening.
1.1 This practice covers the preparation of an optical microscope for dimensional measurements. It is intended for preparing an optical microscope to measure the width of lines, in the range from 0.5 to 12 [mu]m, inclusive, on hard-surface photomasks and processed silicon wafers. 1.2 This practice...
