ISO 27627:2014 pdf free.Petroleum and natural gas industries一Aluminium alloy drill pipe thread connection gauging
ISO 27627 specifies the technical delivery condition, manufacturing process, material requirements, configuration and dimensions, and verification and inspection procedures for aluminium alloy drill pipes manufactured in accordance with ISO 15546.
This International Standard also specifies the gauging procedure for taper buttress thread (right and left) and adjoining tapered stabilizing shoulders (bores) made of aluminium alloy drill pipes and related steel tool joints.

ISO 15546, Petroleum and natural gas industries一Aluminium alloy drill pipe
For the purposes of this document, the following terms and definitions apply.
set of screw and plain gauges of one standard size, associated among themselves under metrological characteristics
imaginary plane, perpendicular to the thread axis of rotary shouldered connections at which the pitch diameter at gauge point is measured
gauge used for calibration of other gauges
axial distance between successive threads, which, in a single start thread, is equivalent to lead
gauge to control internal diameter over the basic plane of the internal taper thread or diameter in the design plane of plain tapered bore of the drill pipe tool joint
Note 1 to entry: See Reference.[1]
gauge to control external diameter over the basic plane of the external taper thread or diameter in the design plane of plain tapered shoulder of drill pipe
imaginary plane, perpendicular to the thread axis of rotary shouldered connections used for design and inspection of the thread
gauge to control normalized effective and external diameters of the internal taper thread with buttress profile
gauge to control normalized effective and internal diameters of the external taper thread with buttress profile
taper surface adjoining drill pipe taper thread and used for increase of fatigue resistance of connection with drill pipe tool joint
