Overview

EN 60512-16-4:2008 (identical to IEC 60512-16-4:2008) specifies a standard test method to determine the tensile strength of crimped connections used in connectors for electronic equipment. Part of the IEC 60512 series, this mechanical test (Test 16d) describes specimen preparation, test equipment and mounting, the tensile test procedure, and required measurements and records. It is intended for use where a detail specification calls for verification of crimp strength.

Key topics and requirements

• Scope and purpose: Establishes a repeatable method to measure tensile strength of a contact or terminal crimped to a conductor.
• Specimen preparation:
  • Specimen = contact/terminal crimped to conductor per the relevant detail and tooling specification.
  • Cable insulation supports or clamping devices not part of the crimp must be rendered inoperative.
  • Optional: crimping a specimen at each end of a conductor may be treated as one specimen.
• Equipment and mounting:
  • Use a tensile testing machine with appropriate fixtures.
  • Mount so axial load is applied to the crimp without damaging the crimp barrel with the jaws.
• Test procedure:
  • Apply tension at a machine head travel rate between 25 and 50 mm/min until conductor pull-out or breakage.
• Measurements and records:
  • Perform visual examination before and after test in accordance with IEC/EN 60512-1-1.
  • Record load at break and the testing machine head travel rate; record nature and characteristics of the breakage.
  • Elongation vs. load curves are useful but not required.
• Details to be specified in a detail specification:
  • Preconditioning, conductor size(s), tooling details, use of lubricants, special mounting, number of specimens, minimum ultimate load (if not specified, reference IEC 60352-2), and any deviations from the standard method.

Applications and users

Who uses EN 60512-16-4:2008:

• Connector and terminal manufacturers validating crimp process and connector performance
• Test laboratories performing mechanical qualification and routine production testing
• Product R&D and quality assurance teams for design verification
• Procurement and specification writers who need objective acceptance criteria for crimped connections Practical applications include production process validation, failure analysis, supplier qualification, and compliance testing for electrical and electronic equipment.

Related standards

• IEC/EN 60512-1 and IEC/EN 60512-1-100 (general structure and visual examination)
• IEC 60352-2 (solderless connections - crimped connections: requirements and test methods) - referenced for default ultimate load values if not given in detail specification.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also partic
