Din En 60352-2 Pdf Today
DIN EN 60352-2 defines standardized test methods and acceptance criteria for evaluating the mechanical, electrical, and environmental performance of soldered electrical connections. It is essential for manufacturers and test labs to qualify solder processes and ensure reliable, long-lived joints in electronic and electrical assemblies. For implementation, use calibrated test equipment, representative specimens, and the current edition of the standard from an authorized source.
This report outlines the technical requirements, test procedures, and recent updates for DIN EN 60352-2 (identical to IEC 60352-2
), which governs solderless crimped connections in electrical and electronic equipment. 1. Scope and Application
The standard applies to solderless crimped connections made with: Stranded conductors Solid conductors in diameter. Exclusions : It specifically does apply to the crimping of coaxial cables. iTeh Standards 2. General Requirements
The standard ensures that crimped connections remain electrically stable under prescribed mechanical, electrical, and climatic conditions. Key prerequisites include: iTeh Standards Crimp Barrels
: Requirements for uninsulated or pre-insulated barrels, with a focus on tensile strength rather than older Vickers hardness metrics.
: Changes to surface finishes now favor tin-alloys or nickel over tin-lead to comply with legislation.
: Crimping must be performed using tools approved by manufacturers that meet the standard's performance criteria. iTeh Standards 3. Core Test Methods
To validate a crimp, several standardized tests are performed: DIN EN IEC 60352-2:2023-03 - Draft
The standard provides guidelines for visual inspection of the crimp profile (e.g., bell mouth shape, wire brush position, insulation crimp position) to detect defects like under-crimping, over-crimping, or chopped strands.

The DIN EN 60352-2 standard (currently updated as DIN EN IEC 60352-2) specifies the general requirements, test methods, and practical guidance for solderless crimped connections used in electrical and electronic equipment. It is the German implementation of the international IEC 60352-2 standard. Core Specifications
The standard defines the parameters for achieving a homogeneous, permanent connection between a conductor and a connecting element without using solder. Applicable Wire Ranges: Stranded wires: to cross-section. Solid wires: to diameter.
Excluded Materials: Specifically does not apply to the crimping of coaxial cables.
Product Classifications: Categorizes end-products into three classes to tailor testing: Class A: General electrical and electronic products. Class B: Dedicated service products.
Class C: High-performance electrical and electronic products. Key Technical Requirements
The standard ensures electrical stability under mechanical and climatic stress through specific criteria:
Contact Resistance: Provides formulae and graphs (such as Curve A and Curve B) to determine maximum allowed initial resistance and the maximum permitted change after environmental conditioning.
Tensile Strength: Defines minimum pull-out forces based on wire cross-section to ensure mechanical durability.
Test Currents: Specifies test current recommendations for different wire sizes (e.g., for wires up to ).
Surface Finishes: Updates include moving from tin-lead to tin-alloy finishes to comply with RoHS legislation. IEC 60352-2:2024

DIN EN 60352-2 standard (equivalent to IEC 60352-2 ) provides the essential requirements, test methods, and practical guidance for solderless crimped connections
. It ensures that electrical connections are stable and reliable under various mechanical, electrical, and environmental conditions. Scope and Applicability
The standard covers crimped connections used in electrical and electronic equipment, specifically: Wire Types : Stranded wires with a cross-section of 0.05 mm² to 10 mm² or solid wires with a diameter of 0.25 mm to 3.6 mm Excluded Items apply to the crimping of coaxial cables
: Includes both uninsulated and pre-insulated crimp barrels. iTeh Standards Key Performance Requirements
To ensure a high-quality connection, the standard defines several critical criteria: Tensile Strength : The resistance to tensile stress must be at least
of the breakage load of the annealed copper wire for sections up to 1.5 mm². Electrical Stability : It provides test procedures for contact resistance test currents to verify performance under load. Mechanical Integrity
: Requirements include proper crimp height and the avoidance of common faults, such as open barrels or incorrect wire insertion. Advantages of Compliant Crimping
Following DIN EN 60352-2 offers several benefits over traditional soldering: Efficiency
: Allows for high-speed manufacturing with automatic machines or manual tools. Related search suggestions: (functions
: Eliminates health risks from heavy metals or soldering fumes. Reliability
: Avoids "cold solder joints" and ensures that the spring characteristics of contacts are not damaged by heat. Standardized Testing Methods The standard details specific validation tests, including:
EN 60352-2:1994 - Solderless crimped connections - iTeh Standards
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.
"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).
