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.
The standard provides tables specifying the minimum force required to pull a wire out of a crimp barrel. For example:

A warning: Avoid free PDFs from random websites. Many are outdated (e.g., 2006 edition vs. 2024 edition), missing critical annexes, or contain corrupted tables. A wrong crimp height spec can literally cause the failure in the story.
In summary: DIN EN 60352-2 is the bible for making metal stick to metal when screws, solder, and hope have failed. The story of the Arctic Dawn is fiction, but every detail—the 135 N pull force, the crimp height gauge, the intermittent failure from cold flow—is real. Now go find the PDF, and may your terminations never flicker.
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 din en 60352-2 pdf
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.
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. Ensure your pull tester and micrometer are calibrated
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

The standard DIN EN 60352-2 (often searched for in its PDF format) is the definitive guide for engineers and manufacturers working with solderless crimped connections. It provides a standardized framework to ensure that electrical and electronic equipment remains reliable under mechanical stress and varying environmental conditions.
Below is a detailed overview of the standard’s scope, technical requirements, and current status. 1. Scope and Application
The primary goal of DIN EN 60352-2 is to determine the suitability of crimped connections by evaluating them under specified mechanical, electrical, and atmospheric conditions.
Conductor Compatibility: The standard covers stranded wires with a cross-section of 0.05 mm² to 10 mm² and solid wires with a diameter of 0.25 mm to 3.6 mm.
Excluded Technologies: Notably, this standard does not apply to the crimping of coaxial cables.
Industries: It is widely used in telecommunications, automotive wire harnesses, and industrial electronic devices. 2. Current Editions and Updates
As of late 2024 and 2025, the standard has seen significant updates to align with international IEC 60352-2 versions. IEC 60352-2:2024
