CEN/SS I09 - Small tools

ISO 6789-2:2017 specifies the method for the calibration of hand torque tools and describes the method of calculation of measurement uncertainties for the calibration.
ISO 6789-2:2017 specifies the minimum requirements for the calibration of the torque measurement device where the relative measurement uncertainty interval, W´md, is not already provided by a traceable calibration certificate.
ISO 6789 is applicable for the step by step (static) and continuous (quasi-static) calibration of torque measurement devices, the torque of which is defined by measuring of the elastic form change of a deformable body or a measured variable which is in proportion to the torque.
ISO 6789-2:2017 applies to hand torque tools which are classified as indicating torque tools (Type I) and setting torque tools (Type II).
NOTE          Hand torque tools covered by this document are the ones identified in ISO 1703:2005 by reference numbers 6 1 00 11 0, 6 1 00 11 1 and 6 1 00 12 0, 6 1 00 12 1 and 6 1 00 14 0, 6 1 00 15 0. ISO 1703 is currently under revision. In the next edition, torque tools will be moved to an own clause, and with this change the reference numbers will also change and additional reference numbers will be added.

ISO 6789-1:2017 specifies the conformance testing and marking requirements for hand torque tools used for controlled tightening of screws and nuts. It also specifies the minimum requirements for declaration of conformance for hand torque tools.
ISO 6789-1:2017 applies to hand torque tools which are classified as indicating torque tools (Type I) and setting torque tools (Type II).
NOTE          Hand torque tools covered by this document are those identified in ISO 1703:2005 by reference numbers 6 1 00 11 0, 6 1 00 11 1 and 6 1 00 12 0, 6 1 00 12 1 and 6 1 00 14 0, 6 1 00 15 0. ISO 1703 is currently under revision. In the next edition, torque tools will be moved to an own clause, and with this change the reference numbers will also change and additional reference numbers will be added.
ISO 6789-1:2017 does not specify requirements of calibration certificates for hand torque tools. These are described in ISO 6789‑2.

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.

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.

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.

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.

ISO 6789:2003 specifies the requirements for, and describes the test methods and marking of, hand torque tools used for controlled tightening of bolted connections.
It applies in particular to indicating and setting torque wrenches in accordance with numbers 258 and 259 of ISO 1703:1983.

This secind edition cancels and replaces the first edition (ISO 4231:1977). Is a supplement to ISO 2568 and ISO 4230 and lys down the diemensions of these screwing dies intended for production of parallel pipe threads in accordance with ISO 228-1. Diameter, thickness and fixing dimensions are accordance with ISO 2568 so as to permit the driving of and-oprated dies with the aid of the die stocks defined in that document.

This second edition cancels and replaces the first edition (ISO 4230:1977). Is a supplement to ISO 2568 and ISO 4231 and lys down the dimensions of these screwing dies intended for production of taper pipe threads in accordance with ISO 7-1. With the exception of the die 1/16, the 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.
