25.100.50 - Taps and threading dies

IEC 62841-3-12:2017 applies to transportable threading machines. The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools are given in Annex K. This standard deals with the hazards presented by tools which are encountered by all persons in the normal use and reasonably foreseeable misuse of the tools.

ISO 529:2017 specifies the general dimensions of short machine taps and hand taps. These dimensions, established as functions of the thread diameter and pitch, are the following: - length of thread (maximum); - overall length; - shank diameter and dimensions of driving square; - dimensions of the connecting portion between the shank and threaded part. ISO 529:2017 is applicable to taps intended for cutting the following threads: a) ISO metric threads: - coarse pitch; - fine pitch; b) ISO inch th...view more

ISO 2284:2017 specifies the general dimensions and marking of hand taps for pipe threads. It is applicable to the two following types of tap: - taps for parallel threads (see Figure 1 and Table 1), - taps for taper threads (see Figure 2 and Table 2), having threads in accordance with ISO 7‑1 and ISO 228‑1. Furthermore, it gives in Annex A the bases used for calculation of the dimensions, and in Annex B the relationship between designations in this document and the ISO 13399 series.

This International Standard is a supplement to ISO 2568 and ISO 4230 and specifies the dimensions of
hand- and machine-operated circular screwing dies intended for production of parallel pipe threads,
G series, in accordance with ISO 228-1.
The general dimensions of these dies (diameter, thickness and fixing dimensions) are in accordance
with ISO 2568 so as to permit the driving of hand-operated dies with the aid of the die stocks defined in
that document.

This International Standard is a supplement to ISO 2568 and ISO 4231 and specifies the dimensions
of hand- and machine-operated circular screwing dies intended for production of taper pipe threads,
R series, in accordance with ISO 7-1.
With the exception of the die 1/16, the general dimensions of these dies (diameter, thickness and fixing
dimensions) are in accordance with ISO 2568 so as to permit the driving of hand-operated dies with the
aid of the die stocks defined in that document.

ISO 4231:2016 is a supplement to ISO 2568 and ISO 4230 and specifies the dimensions of hand- and machine-operated circular screwing dies intended for production of parallel pipe threads, G series, in accordance with ISO 228‑1.
The general dimensions of these dies (diameter, thickness and fixing dimensions) are in accordance with ISO 2568 so as to permit the driving of hand-operated dies with the aid of the die stocks defined in that document.

ISO 4230:2016 is a supplement to ISO 2568 and ISO 4231 and specifies the dimensions of hand- and machine-operated circular screwing dies intended for production of taper pipe threads, R series, in accordance with ISO 7‑1.
With the exception of the die 1/16, the general dimensions of these dies (diameter, thickness and fixing dimensions) are in accordance with ISO 2568 so as to permit the driving of hand-operated dies with the aid of the die stocks defined in that document.

IEC corrigendum

ISO 4231:2016 is a supplement to ISO 2568 and ISO 4230 and specifies the dimensions of hand- and machine-operated circular screwing dies intended for production of parallel pipe threads, G series, in accordance with ISO 228‑1. The general dimensions of these dies (diameter, thickness and fixing dimensions) are in accordance with ISO 2568 so as to permit the driving of hand-operated dies with the aid of the die stocks defined in that document.

ISO 4230:2016 is a supplement to ISO 2568 and ISO 4231 and specifies the dimensions of hand- and machine-operated circular screwing dies intended for production of taper pipe threads, R series, in accordance with ISO 7‑1. With the exception of the die 1/16, the general dimensions of these dies (diameter, thickness and fixing dimensions) are in accordance with ISO 2568 so as to permit the driving of hand-operated dies with the aid of the die stocks defined in that document.

ISO 8051:2016 specifies the dimensions for full-diameter shank taps with recess with nominal diameters from M3 to M10 and thus complements ISO 2283, which concerns relieved shank taps. It applies to long shank machine taps. Technical specifications for taps covered by ISO 8051:2016 (including marking) are given in ISO 8830.

This standard applies to hand-held tappers and threaders.

IEC 61029-2-12:2010 applies to machines for creating external threads that either rotate the work piece or the cutting head.

IEC 61029-2-12:2010 applies to machines for creating external threads that either rotate the work piece or the cutting head.

Is valid for the short taps specified in ISO 529 as well as for any other kind of ground thread taps with the same diameters and pitches. The internal threads produced with those taps are conventionally designated by the simplified denomination of "nut" in agreement with the word used in ISO 965 for the general designation of all internal threads.

Specifies how to prepare detail specifications for power
transformers. Includes a blank detail specification, which shows
the format, and indicates which tests are considered to be
appropriate to this type of component.

Gives terms in the three official languages of ISO (English, French and Russian) and in addition to these the equivalent terms in German and Italian. ISO 5967 serves as a reference for tap users and manufacturers. The diagramms given, however, are only to illustrate the terminilogy as tap design can vary according to the manufacturer. Includes nomenclature of the main types of taps,styles of threaded portion, sets of taps, dimansional charcteristics and thread profiles.

Describes material and hardness, cutting geometry, run-out tolerances, and the marking. Applies to standard taps in accordance with ISO 529, ISO 2283, ISO 2284, and ISO 2857.
