This Standard specifies the length, flatness, variation in length, surface finish, hardness, temporal stability, cross-section dimensions, chamfer and side-face squareness for gage blocks.

This Document defines and describes the proper measurement of any flow required or recommended by any of the Performance Test Codes [PTC].

This Standard has information on dial indicator design styles, size groupings, maximum permissible errors (indication and hysteresis), and appendices on testing, uncertainty and electronic indicators.

This document presents a summary discussion of temperature measurement as related to Performance Test Code work with particular emphasis on basic sources of error and means for coping with them.

This Standard provides specifications, measurement methods, and means of determining measurement uncertainty for outside, inside, and depth micrometers, including those with digital readout.

This Standard address the role of measurement uncertainty when accepting or rejecting a product based on a measurement result and a product specification; terminology and rules are presented.

This document presents a summary discussion of pressure measurement as related to Performance Test Code work with particular emphasis on basic sources of error and means for coping with them.

This Standard examines how to assess the reliability of dimensional measurement uncertainty statements and how to resolve technical disagreements involving their evaluation.

This Standard is for cylindrical ring gages used to set and calibrate measuring instruments and check external diameters, including tolerances and measuring methods.

This Standard specifies the geometric and method of use for orifice meters of 6 mm to 40 mm (1/4 in. to 1 ½ in.) line size when they are inserted in a conduit running full.

This Standard discusses issues when taking measurements not at the standard temperature. Also discussed is the calculation of thermal time constants, or “soak-out time” and the “thermal error index”.

This Standard specifies requirements for preparation and approval of dimensional measurement plans and for the use of approved plans in making dimensional measurements.

This Standard is for cylindrical plug gages and master discs used to set and calibrate measuring instruments and check internal diameters, including tolerances and measuring methods.

This Standard establishes uniform practices for the measurement of thread measuring wires. Wires include inch series 60-deg, 29-deg Acme, 7/45 Buttress, and metric 60-deg threads.

This Standard consists of a collection of definitions of those terms that pertain to the measurement of fluid flow in pipes. Only those terms of general usage have been included.

This Standard provides terminology, definitions, testing and safety considerations of Dial and Digital Type of Pressure Indicating Gauges, Diaphragm Seals, Snubbers and Pressure Limiter Valves.

This Standard mainly deals with precision spindle instruments for out-of-roundness measurement and polar chart presentation, but does not exclude other methods providing valid radial deviation data.

This Standard presents a working outline detailing and illustrating the techniques for estimating measurement uncertainty for fluid flow in closed conduits.

This Standard offers ways of measuring length and parallelism of gage blocks requiring recalibration or certification. Provides methods for determining flatness, surface texture, and wringing quality.

This Standard applies to the steady flow of single-phase gases and deals with devices for which direct calibration experiments have been made.
