This standard specifies requirements for internal micrometers comprising a measuring head, extension rods with or without spacing collars, and, in the smaller sizes, a handle.<\/p>\n

Provision is made for three sizes of measuring heads, in both metric and inch units, as shown in Table 1 and Table 2.<\/p>\n

\n

NOTE Attention is drawn to the fact that metric dimensions are not necessarily direct conversions of the imperial dimensions.<\/p>\n<\/blockquote>\n

Table 1<\/b> Measuring heads \u2014 metric measurements<\/p>\n

Table 2<\/b> Measuring heads \u2014 inch measurements<\/p>\n

This standard also covers stick micrometers, which are designed for the measurement of longer internal lengths, and comprise the following parts:<\/p>\n

    \n
  1. \n

    a 150 mm or 300 mm or 6 in or 12 in micrometer unit, fitted with a micrometer of 25 mm or 1 in range, and having rounded terminal faces;<\/p>\n<\/li>\n

  2. \n

    a series of extension rods which, together with the micrometer unit, permit a continuous range of measurement up to the maximum length required.<\/p>\n<\/li>\n<\/ol>\n

    Annex A gives a method of test for the accuracy of internal micrometer readings.<\/p>\n
