Mastering Solderless Connections: A Deep Dive into DIN EN 60352-2

In the world of electrical engineering, the reliability of a connection can make or break a product. While soldering is common, solderless crimped connections are often the preferred choice for their mechanical strength and ease of assembly in high-volume production.

If you are looking for the DIN EN 60352-2 PDF, you are likely seeking the "gold standard" for crimping requirements. This European standard (equivalent to the international IEC 60352-2) defines the general requirements and test methods for these critical components. What is DIN EN 60352-2?

The DIN EN 60352-2 standard specifically covers solderless crimped connections. It provides a comprehensive framework to ensure that connections remain electrically stable and mechanically sound under various environmental conditions. Key Specifications: din en 60352-2 pdf

Wire Ranges: Applicable for stranded wires (0.05 mm² to 10 mm² cross-section) and solid wires (0.25 mm to 3.6 mm diameter).

Target Devices: Primarily used in telecommunications, electrical, and electronic equipment.

Exclusions: It does not apply to the crimping of coaxial cables. Why Compliance Matters

Using a connection that meets DIN EN 60352-2 ensures that your product is built to a globally recognized level of quality. Compliance helps:

Guarantee Reliability: Standardized test methods verify that the crimp will hold up over time.

Facilitate Certification: Meeting these standards is often a prerequisite for CE, RoHS, and other safety markings.

Tooling Consistency: It provides a way to compare results even when using tools from different manufacturers. IEC 60352-2:2024

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

Act 1: The Failure

In the control room of the Arctic Dawn, a semi-submersible drilling rig north of Norway, engineer Lena Vogel watched the master alarm panel flicker. Not a full failure. A ghost. Every 47 minutes, the pressure reading from the BOP (blowout preventer) would stutter, drop to zero for 0.3 seconds, then recover.

“Transient fault,” muttered the electronics technician, Kai. “Ground loop? Cold solder joint?”

Lena shook her head. The BOP’s control system was her responsibility. A false zero could trigger an emergency shutdown, costing millions. But a real zero ignored? Catastrophic.

They traced the signal path: sensor → junction box → main cabinet → PLC. At the junction box, Kai opened the lid. Inside, a sea of wires terminated on terminal blocks. Most were tight. One wire—a blue 0.5 mm² control signal wire—looked fine, but when Kai wiggled it, the alarm flickered.

“The screw terminal is tight,” Kai said, puzzled. “But the wire pulls straight out.”

Lena took a magnifying glass. The copper strand wasn’t broken. It was indented—crushed flat by the screw, but not wrapped or secured. Over months of vibration from the rig’s pumps, the crushed wire had cold-flowed, slowly relaxing like a squeezed spring. The electrical connection was now just a point of loose metal-on-metal contact, oxidizing and failing intermittently.

“Someone didn’t read the standard,” Lena said.

Act 2: The Standard

Back in her office, Lena pulled up her technical library. She needed the rulebook for making a wire termination that survives hell—salt, vibration, temperature swings. She searched for DIN EN 60352-2.

The PDF opened. The title: Solderless connections - Part 2: Crimped connections - General requirements, test methods and practical guidance.

This wasn't just a suggestion. It was a harmonized European standard (EN), identical to the international IEC 60352-2, and adopted by Germany as DIN. For any industrial equipment sold in the EU, compliance wasn't optional.

She scrolled past the foreword to the core.

Clause 4: Requirements. A crimped connection must be a cold weld—the wire strands and the terminal barrel must deform plastically into a single, gas-tight, homogeneous mass. No solder. No screw. Just a controlled crush.

Clause 5: Test methods. Pull force. A 0.5 mm² wire must withstand at least 135 N of pull without detaching. Voltage drop under 5 mV per ampere. Salt spray. Thermal cycling. A crimp is not a crush

Annex A (normative): The crimp tool calibration. This was the killer. You cannot use pliers. You cannot use a generic ratchet. You must use a calibrated indentor or die that matches the terminal type. The tool must be verified daily with a "C-clamp" or "crimp height gauge."

Lena slapped the table. That was it. The rig’s maintenance log showed the last electrician had used a universal plier-style crimper for the BOP terminal. The crimp height was wrong—too low, crushing strands into a weak hourglass shape; or too high, leaving a loose sleeve. Either way, no gas-tight seal.

Act 3: The Solution

Lena walked to the workshop. In the locked tool cabinet, she found the approved crimp tool: a pneumatic press with interchangeable die sets, last calibrated three months ago. Beside it, a crimp height comparator—a precision micrometer block with a slot. For a 0.5 mm² wire, the target crimp height after crimping (the barrel’s compressed outer dimension) was specified in a table in the PDF: typically 1.05 mm ±0.05 mm.

She cut a fresh terminal, stripped exactly 7 mm of insulation (per Clause 4.3), inserted the wire fully, and crimped. The terminal emerged with parallel indentations—a perfect "B-crimp" (insulation grip and conductor crimp in one). She measured it: 1.04 mm. Pass.

She pulled the wire with a small force gauge: 148 N before the wire broke—outside the terminal. The connection itself held.

Back at the junction box, she replaced all six terminals on the BOP circuit, crimping each with religious precision. Then she used a pull tester (a spring scale) to verify each one. Finally, she applied a voltage drop test per Clause 5.2: 1 amp through the joint, measure millivolts across it. Result: 0.8 mV—well below the 5 mV limit.

The alarm never flickered again.

Act 4: The Lesson

That night, Lena saved a permanent copy of DIN EN 60352-2.pdf on the rig’s offline server. She added a one-page summary to the maintenance binder:

A crimp is not a crush.

The next audit, the certifying authority (DNV) asked for proof of crimp tool calibration. Lena produced logs, photos of crimp height measurements, and pull test records. The auditor nodded. "You read the standard."

"No," Lena said. "I bled for it."

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.

DIN EN 60352-2 is a European adoption of the IEC standard that covers requirements and tests for soldered electrical connections — specifically, soldered connections made by manual soldering and by soldering irons. It specifies materials, joint types, workmanship requirements and mechanical/electrical test methods to ensure reliable soldered joints in electronic and electrical assemblies.
