DIN EN 60352-2 is the European standard (equivalent to IEC 60352-2) that specifies requirements and test methods for solderless crimped connections. Core Content Overview
This standard ensures that electrical connections made by crimping—deforming a terminal around a wire—are reliable, durable, and perform consistently under mechanical and environmental stress.
Scope: It covers solderless connections made with stranded wires (0.05 mm2m m squared mm2m m squared
cross-section) and solid wires (0.25 mm to 3.6 mm diameter). Key Requirements:
Mechanical Strength: Defines the minimum tensile force (pull-out force) a connection must withstand based on the wire size.
Electrical Performance: Specifies maximum contact resistance levels to prevent overheating.
Workmanship: Requirements for the crimp height, width, and visual characteristics (e.g., no cracked insulation, all wire strands captured).
Test Procedures: Outlines how to perform vibration tests, temperature cycling, and corrosion testing to simulate a full product lifecycle. Where to Access the Document

The DIN EN 60352-2 standard is the European adoption of the international IEC 60352-2 standard, which governs the technical requirements and testing procedures for solderless crimped connections.
Because this is a copyrighted technical document, a full "DIN EN 60352-2 PDF" is typically only available for purchase through official standards bodies like DIN (Deutsches Institut für Normung) or Beuth Verlag. However, the following informative overview outlines the critical engineering requirements and testing protocols defined within the standard. 1. Scope and Application
The standard applies to solderless crimp connections made with stranded wires from or solid wires from
in diameter. It is primarily used in telecommunications, industrial electronics, and automotive wiring to ensure electrical continuity and mechanical stability without the use of solder. 2. Key Technical Requirements
To comply with DIN EN 60352-2, a crimp connection must meet specific physical criteria: din en 60352-2 pdf
Deformation: The crimp barrel must be sufficiently deformed to compress all wire strands into a gas-tight mass, preventing oxidation.
Wire Position: The conductor must be visible at the front end of the crimp barrel (the "brush"), and the insulation must be properly supported by the insulation crimp without entering the electrical connection zone.
Material Compatibility: The standard specifies that the crimp barrel and the wire should have compatible finishes (e.g., tin-plated) to prevent galvanic corrosion. 3. Essential Testing Procedures
The standard defines several tests to validate the quality of the connection:
Tensile Strength (Pull-out Force): One of the most critical tests. It defines the minimum force (in Newtons) required to pull the wire out of the crimp. For example, a wire typically requires a minimum pull-out force of
Contact Resistance: Measures the electrical resistance across the connection. It must remain below a specified milliohm ( ) threshold even after environmental aging.
Microsection Analysis: A destructive test where the crimp is cut cross-sectionally and polished. Engineers look for "voidless" compression, where no air gaps remain between the wire strands. 4. Why Compliance Matters Using DIN EN 60352-2 compliant connections ensures:
Long-term Reliability: Resistance to vibration and thermal cycling.
Safety: Prevention of overheating caused by high contact resistance.
Interchangeability: Consistency across different manufacturers of crimp tools and terminals. 5. Accessing the Document

DIN EN 60352-2 standard (equivalent to IEC 60352-2) is the primary international technical specification for crimped connections
. It defines the requirements, tests, and application guidance for solderless electrical connections made with stranded or solid wires. Core Objective
The standard ensures that crimp connections are mechanically stable and electrically reliable over their service life. It provides a standardized framework for manufacturers to validate that their crimp tools, terminals, and wires work together as a "crimping system."

DIN EN 60352-2 is the definitive technical standard for solderless crimped connections used in electrical and electronic equipment. It establishes the general requirements, standardized test methods, and practical guidance needed to ensure that crimped connections remain electrically stable and mechanically secure throughout their service life. Scope and Applicability
The standard covers connections made with uninsulated or pre-insulated crimp barrels and applies specifically to: Stranded wires: Cross-sections ranging from 0.05 mm2m m squared mm2m m squared . Solid wires: Diameters ranging from 0.25 mm to 3.6 mm.
Note that this standard specifically excludes the crimping of coaxial cables. For wire sections exceeding 10 mm2m m squared mm2m m squared
), industry professionals often refer to alternative standards like NF F 61-030. Key Requirements of DIN EN 60352-2
The standard ensures reliability by defining strict parameters for the crimping process:
Mechanical Integrity: It specifies the necessary pull-out force (tensile strength) that a connection must withstand to prevent accidental detachment.
Electrical Stability: Requirements include maximum allowable contact resistance and specific test currents to ensure efficient power or signal transmission without overheating.
Environmental Durability: Connections are tested against atmospheric conditions, including temperature rapid changes, dry heat, and damp heat, to simulate long-term field use.
Workmanship: The standard provides guidance on wire preparation (cutting and stripping) and the selection of appropriate crimping tools and barrel materials. Testing Schedules
To verify compliance, DIN EN 60352-2 outlines two primary testing paths:
Basic Test Schedule: Focuses on standard copper or copper alloy materials. It primarily involves pull-out force tests and current loading cycles on a set number of samples.
Full Test Schedule: Required for "exotic" materials like nickel, steel, or stainless steel. This schedule is more rigorous, including up to 500 current loading cycles and extensive climatic testing to ensure stability in harsh environments. EN IEC 60352-2:2024 - Crimped connections - iTeh Standards
Even before testing, the standard lists visual acceptance criteria:
A: As of 2025, the current version is DIN EN 60352-2:2020-12 (published December 2020). It supersedes the 2006 edition.
Ensure your pull tester and micrometer are calibrated traceable to ISO/IEC 17025. The standard does not specify brands, but it does require a pulling speed of 25 ± 5 mm/min.
