This International Standard describes the test method to measure a friction coefficient of chemical conversion coating sheet products and coiled products.

It measures the friction coefficient of test pieces without specimen deformation during the test.

Test results can be changed by test conditions such as surface state, normal force, sliding velocity and temperature. Therefore test conditions shall be specified.

This International Standard is permitted to be applied under the same conditions to measure or compare friction properties of Galvanized, lubricated, resin coated steel sheet.

This part of ISO 14713 provides guidelines and recommendations regarding the general principles of design which are appropriate for articles to be hot dip galvanized after fabrication (e.g., to ISO 1461) for corrosion protection, for example, articles manufactured in accordance with EN 1090-2.

The protection afforded by the hot dip galvanized coating to the article will depend upon the method of application of the coating, the design of the article and the specific environment to which the article is exposed. The hot dip galvanized article can be further protected by application of additional coatings (outside the scope of this part of ISO 14713), such as organic coatings (paints or powder coatings). When applied to hot dip galvanized articles, this combination of coatings is often known as a "duplex system".

Specific product-related requirements (e.g. for hot dip galvanized coatings on tubes or fasteners, etc.) will take precedence over these general recommendations.

This standard does not apply to hot dip galvanized coatings applied to continuous sheet (e.g. to EN 10346).

This document specifies two low voltage tests for detecting and locating defects that extend to the basis metal in vitreous and porcelain enamel coatings.

Method A (electrical) is suitable for the rapid detection and determination of the general location of defects. Method B (optical), based on colour effects, is suitable for the more precise detection of defects and their exact locations. Both methods are commonly applied to flat surfaces. For more intricate shapes such as undulated and/or corrugated surfaces ISO 8289-2 has to be applied.

NOTE 1 Selection of the correct test method is critical to distinguish the areas of increased conductivity detected by Method B from actual pores that extend to the basis metal, which can be detected by both methods.

NOTE 2 The low voltage test is a non-destructive method of detecting defects (see Clause 3) and therefore, is completely different from the high voltage test specified in ISO 2746. The result of high and low voltage test are not comparable and will differ.

This International Standard specifies the dimensions and technical requirements for ratcheting wrenches used

in assembly or disassembly of hexagonal and double hexagonal fasteners.

NOTE The wrenches covered by this standard are the ones identified in ISO 1703:2018 under reference

No.1 1 01 07 0, 1 1 01 08 0, 1 1 01 09 0 and 1 1 02 19 0, 1 1 02 20 0.

NOTE The wrenches according to this standard are not intended for uses with impact stress of the wrench.

This document specifies a laboratory method for measuring the vibration at the handle of continuous operating fastener driving tools. It is a type test procedure for establishing the vibration value on the handle of a hand-held power tool operating under a specified load.

This document is applicable for fastener driving tools, driven pneumatically or by other means (see Figure 1). This document is applicable to fasteners comprising nails, staples, pins, etc.

This part of ISO 14649 specifies the process data for additive manufacturing. As with other processes, ISO 14649-17 describes additive manufacturing at the micro process plan level without making a commitment to particular machines or processes. This means that ISO 14649-17 differentiates between explicit data and derived data. Support structures, for example, depend on the shape and process. These should be derived, therefore, when the process and the machine are chosen in order to achieve maximum flexibility. The workingstep structure is, though, sufficiently flexible to allow support structures to be added explicitly, should they be required. Assemblies can be described with different elements, with different materials, in different workingsteps. However, additive manufacturing can be either sequential or parallel, in contrast to other manufacturing techniques such as milling, turning or EDM which are sequential. For this reason, there is also a possibility to define explicit parallel features.

This part of ISO 26623 specifies dimensions for polygonal taper interfaces with flange contact surface — Polygon-shanks for automatic and manual tool exchange to be applied on machine tools (e. g. turning machines, drilling machines, milling machines and turn/milling centres as well as grinding machines). A range of shank sizes is specified.

These shanks incorporate a grooved flange to enable automatic tool exchange. The clamping can be realized by a circular groove using clamping segments or internal screw threads using centre-bolts.

The torque is transmitted by form lock (polygon).
