SIST EN 60512-16-20:2002

Overview

EN 60512-16-20:1996 (also published as IEC 60512-16-20) specifies a standardized method to assess the mechanical strength of wired terminations on solderless connections, including designs with integrated strain relief features. It is part of the IEC/EN 60512 series for electromechanical components and is relevant to plug-and-socket devices and connectors (ICS 31.220.10). The Slovenian adoption appears as SIST EN 60512-16-20:2002.

Key topics

• Scope and purpose: Standardized approach to determine the mechanical robustness of solderless (non‑solder) wire terminations.
• Test focus: Mechanical strength of the wired termination, including evaluation of integrated strain relief mechanisms that protect contacts and conductors from mechanical loads.
• Test methodology: Defines a repeatable test method for applying mechanical load to wired terminations and for assessing performance after loading (sample preparation, test execution and evaluation criteria are provided in the standard).
• Applicable components: Connector contacts, terminations and associated assemblies where solderless connections are used.
• Quality objectives: Ensure reliable electrical continuity and mechanical retention under expected handling and service stresses.

Applications

Who uses EN 60512-16-20 and why:

• Connector and cable-assembly manufacturers - to validate design robustness and to demonstrate that solderless terminations meet mechanical durability expectations.
• Design and development engineers - to select or design appropriate strain relief features and termination methods for reliable product performance.
• Test laboratories and QA teams - for routine qualification testing, incoming inspection, and failure analysis of solderless terminations.
• Procurement and compliance officers - to specify mechanical strength requirements and to verify supplier conformity in technical specifications and contracts.

Practical benefits:

• Reduces risk of field failures caused by wire pull-out, contact loosening or strain-induced damage.
• Supports product qualification, certification and lifecycle reliability assessments.
• Provides a common reference for suppliers and customers when specifying solderless termination strength.
