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
: 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

At "ElectraFlow Solutions," a high-end industrial machinery firm, production had ground to a halt. Their new control panels were failing final inspection: wires were literally pulling out of their terminals. din en 60352-2 pdf
"It's the tools," the assembly lead insisted. "We bought the most expensive ratcheting crimpers on the market."
Marcus, the lead engineer, pulled up his copy of DIN EN 60352-2 (the German-adopted version of IEC 60352-2). He knew that "expensive tools" didn't guarantee a "standard-compliant connection." Step 1: Matching the "Recipe"
Marcus opened the PDF and pointed to the Scope. The standard covers stranded wires from 0.05 mm² to 10 mm² and solid wires from 0.25 mm to 3.6 mm. He checked their current assembly: they were trying to crimp a 12 mm² cable using a tool only rated up to 10 mm²—a classic AWG mismatch. Step 2: The Tensile Test
To prove the failure, Marcus used the Test Methods section of the standard. He set up a pull-out force test (tensile test).
First, let’s decode the nomenclature. The standard is officially titled: "Solderless connections – Part 2: Crimped connections – General requirements, test methods and practical guidance."
In essence, this document defines how a proper crimped connection must look, how it must perform under stress (mechanical, thermal, and electrical), and how to test it to destruction (or non-destruction) to ensure quality.
DIN EN 60352-2 is the German national adoption of the European standard EN 60352-2, which is identical to the international standard IEC 60352-2.
The full title of the standard is:
"Solderless connections – Part 2: Solderless crimped connections – General requirements, test methods and practical guidance."
This standard is the definitive technical document used in the electronics and electrical engineering industries to ensure the quality, reliability, and safety of crimped connections—the most common method for terminating wires into connectors.
Compare your current crimp specifications (crimp height, pull force, tool change intervals) against the standard. Document any differences.
Searching for a din en 60352-2 pdf is the first step toward ensuring that your crimped connections are reliable, safe, and legally compliant. While the temptation to find a free copy is high, the cost of non-compliance—failed audits, rejected shipments, or field failures—far outweighs the price of a genuine document.
Remember: A PDF is just a file. What matters is implementing the standard correctly. Use the official PDF to train your team, calibrate your pull testers, and audit your crimp cross-sections. In doing so, you turn a technical document into a competitive advantage.

In the fluorescent-lit silence of the validation lab, Elara tightened the torque wrench one last time. The connector clicked into place. On her screen glowed the standard: DIN EN 60352-2:2006-11.
Eighteen months of her life had distilled into this single, cold crimp.
The project was codenamed "Ariadne"—a wire harness for the new Europa-class subsea drones. These drones dove seven kilometers into the abyssal plain, where the pressure could crush a steel drum like paper. If a connection failed down there, the drone wouldn't just stop working. It would implode. And with it, five years of research and three careers.
Elara’s rival, Markus, had argued for soldering. "Old-world craftsmanship," he called it. "A proper weld of metals. Reliable."
Elara pointed to the standard. "Paragraph 4.2.2," she said. "Vibration. Thermal cycling. Corrosion. A soldered joint wicks flux into the strand, makes it brittle. A crimp, done right, is cold-welded. The copper grains actually fuse under pressure. DIN EN 60352-2 isn't a suggestion. It's physics."
Markus scoffed. "You trust a machine over a human hand?"
She had replied, "I trust the tensile pull test. Section 6.3."
Tonight was the final validation. The sample sat in the universal tester: a crimped ferrule on a 0.35 mm² stranded wire, exactly as defined in Table 2 of the standard. The cross-section had been polished and etched—no voids, no visible seam, the wire strands collapsed into a seamless hexagonal column inside the barrel.
She initiated the pull.
The machine groaned. The graph spiked. At 98 newtons—far above the required 85—the wire didn't pull out. Instead, it snapped two centimeters above the crimp. A perfect failure mode. The connection itself had become stronger than the parent metal.
Elara leaned back and exhaled. Pass.
Two months later, Europa-3 descended into the Puerto Rico Trench. Live feeds showed the housing contracting under pressure. Inside, the crimped harness—her harness—held steady. Every sensor returned data. Every millivolt arrived clean.
On the surface, Markus watched the telemetry in silence. Finally, he turned to her.
"The standard," he said quietly. "It won."
She shook her head. "No. The physics won. The standard just wrote it down so we wouldn't have to learn by drowning."
That night, Elara updated the company's internal design rulebook. She added a single line at the top of the crimping section:
Reference: DIN EN 60352-2. No deviations without signed waiver and destructive pull test per Clause 6.3.
She smiled. Some stories don't need heroes. They need a crimp tool, a pull tester, and the courage to trust a cold-welded grain boundary over a beautiful solder joint.
The sea kept its secrets. But her connections never would.

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.
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
