IEC 60352-2-2013 pdf free.Solderless connections – Part 2: Crimped connections – General requirements, test methods and practical guidance.
4 Requirements
4.1 Workmanship
The connection shall be processed in a caretui ano wormaniie manner, in accoroance wiin good current practice.
4.2 Tools
Crimping tools shall be used and inspected according to the instructions given by the tool manufacturer.
The crimping tool shall be able to make uniformly reliable connections during its useful life. The crimping tool shall be equipped with the appropriate dies. Where the dies are adjustable, the correct setting for the barrel to be crimped shall be used.
Hand crimping tools shall be provided with a full cycle crimping mechanism.
Automatic crimping tools shall be provided with a full cycle crimping mechanism or equivalent sateguard. They shall be correctly set and the setting shall be maintained.
Tools are evaluated by testing crimped connections made with the tools to be evaluated.
4.3 CrImp barrels
4.3.1 Materials
Crimp barrels shall be made of copper or copper alloy with a copper content of 60 %
minimum.
The minimum tensile strength of the material shall not exceed 600 MPa in accordance with
ISO 6892.
Other materials of suitable characteristics may be used, for example nickel, steel. stainless steel. Materials with a high resistivity-coefficient (K values, see 5.2.3.1) or materials exceeding the tensile strength specified above, may not be suitable for certain applications. In these cases, the full test schedule of 5.3.3 shall be applied (see 5.1.1).
4.3.2 DimensIons
The dimensions shall be suitable for stranded wires as specified in 4.4.
4.3.3 Surface finishes
The crimp barrel shall be unpiated or plated with tin, tinalloy. silver, gold or palladium.
The surtace shall be free of contamination and corrosion. Other plating materials, such as nickel. (unless used as under-plate) may be used provided their suitability has been proven. In these cases, the full test schedule of 5.3.3 shall be applied (see 5.1.1).
4.3.4 Design features
The crimp barrel shall be so designed that the crimped connection is achieved by pressure deformation or reshaping of the crimp barrel around the stripped conductor.
NOTE Techniques where the connection is achieved by parts ot barrel penetrating through the insulation of an insulated conductor are not covered by this standard.IEC 60352-2 pdf free download.
