The DIN EN 60352-2 standard is a critical technical document for the electronics and electrical engineering industries, specifically focusing on solderless connections and crimp connections.
Below is a review of the standard's scope, key requirements, and practical application. Purpose and Scope
This standard provides the general requirements, test methods, and practical guidance for crimp connections made with stranded wires or solid conductors. It ensures that electrical connections remain reliable under thermal, mechanical, and atmospheric stress without the use of solder. Key Technical Requirements
Mechanical Strength: Defines the minimum "pull-out force" required for various wire cross-sections to ensure the wire doesn't detach from the terminal.
Electrical Performance: Specifies maximum allowable contact resistance. The connection must maintain low resistance even after aging or environmental exposure.
Visual Inspection: Outlines "good" vs. "bad" crimps, such as the visibility of the wire end (the "brush") and the correct positioning of the insulation support. din en 60352-2 pdf
Crimp Tooling: Emphasizes that the quality of the connection is inseparable from the tool used; it mandates the use of tools that match the specific terminal and wire size. Testing Procedures
The standard details several rigorous tests to validate a crimp design:
Tensile Strength Test: Pulling the wire until it breaks or pulls out.
Contact Resistance: Measuring the voltage drop across the crimp.
Climatic Sequence: Subjecting the connection to temperature cycling and humidity.
Vibration and Shock: Ensuring the connection doesn't loosen under mechanical stress. Practical Application for Professionals
Quality Assurance: It is the "gold standard" for QA departments to verify that their crimping processes are compliant.
Design Engineering: Engineers use it to select the right wire gauges and terminal types for specific current-carrying requirements.
Safety: Compliance is often required for certifications like CE or UL, especially in automotive, aerospace, and industrial machinery. How to Access the PDF

DIN EN 60352-2 standard is the definitive technical framework for "solderless connections," specifically focusing on crimped connections
used in electrical and electronic equipment. It establishes a uniform set of requirements to ensure that these joints are mechanically stable and electrically reliable throughout their service life. iTeh Standards 1. Scope and Core Purpose The primary objective of DIN EN 60352-2 is to define the general requirements, test methods, and practical guidance
for crimped connections. While it is widely used across the electronics industry, the standard specifically targets wires with a maximum cross-section of m m squared
. For larger industrial or railway applications involving wire sections between 10 m m squared m m squared
, engineers typically refer to alternative standards like NF F 61-030. iTeh Standards 2. The Mechanics of a Compliant Crimp
A "crimp" is a solderless joint formed by the controlled plastic deformation of a terminal around a conductor. According to the standard: CETEC Systems Material Integrity
: The process must avoid damaging the individual strands of the wire or the terminal itself. Consistency DIN EN 60352-2 standard (equivalent to IEC 60352-2)
: Consistently high-quality results are best achieved by using tools and contacts from the same manufacturer Positioning
: Conductors must be stripped correctly and inserted to a specific depth—usually the pin insertion depth plus 1mm or 2mm depending on the cross-section—to ensure a full electrical bond. Phoenix Contact 3. Essential Testing and Quality Criteria

3. Ignoring the Manufacturer's Crimp Tool Qualification
The standard requires that the crimping tool (hand tool, press, or automatic) be qualified per Clause 7. Using a generic tool without validation voids compliance.
Key technical topics addressed
- Terminology and definition of soldered joint types (e.g., through-hole, surface-mount, wire-to-terminal).
- Test specimen types and preparation: how to make representative specimens (board layout, component mounting, solder alloy, flux type, pre-treatment).
- Soldering process parameters that may influence results (temperature profiles, wave/hand/reflow/irons, time above liquidus).
- Mechanical tests: tensile, shear, bending, and peel tests for various joint geometries, with defined test fixtures, speeds, and failure criteria.
- Electrical tests: continuity, contact resistance, and tests after environmental stressors.
- Environmental conditioning: thermal cycling, damp heat (humidity), salt spray (where applicable), and thermal shock procedures to evaluate durability under real-world stress.
- Metallurgical examination: cross-sectioning, intermetallic compound (IMC) thickness measurement, and detection of voids, cracks, wetting defects, and incomplete fillets.
- Acceptance criteria: minimum mechanical strengths, allowable resistance changes, visual quality classes, and metallurgical limits (e.g., acceptable IMC growth).
- Statistical sampling and reporting: how to document test setups, specimen counts, measured values, and conformity decisions.
Scope and intended use
- Applies to soldered connections used in electronic equipment and electrical apparatus where permanent joints are required.
- Intended for manufacturers, quality engineers, test labs, and designers who need standardized test methods to qualify solder processes, assembly techniques, and joint designs.
- Useful for process control, failure analysis, supplier qualification, and conformance testing in production and development environments.
3. Voltage Drop (Contact Resistance)
A good crimp should not introduce significant resistance. The standard describes a four-wire measurement method to determine millivolt drop under a specified test current.
