IEC 60352-5 is the international standard for solderless press-in connections used in electronic and telecommunication equipment. It provides the technical roadmap for creating reliable electrical joints by mechanically pressing a terminal into a plated-through hole on a circuit board, eliminating the need for traditional soldering. The Evolution of the Standard
The standard has evolved through several editions to keep pace with advancing technology:
Third Edition (2008): Focused on clarifying materials and adding testing recommendations.
Fourth Edition (2012): Refined design specifications and updated testing methodologies to align with modern manufacturing.
Fifth Edition (2020): The latest revision, which expanded the scope to include non-printed boards (like metal boards) and updated copper thickness limits for plated holes. Key Components & Requirements
The standard ensures that press-in connections can withstand mechanical, electrical, and environmental stress.
Mechanical Integrity: Defines requirements for insertion and push-out (extraction) forces to ensure a secure fit. iec 603525 pdf
Electrical Performance: Specifies methods for measuring contact resistance to ensure stable signal and power transmission.
Environmental Testing: Includes climatic sequence and aging tests to verify long-term stability in various atmospheres.
Dual Test Schedules: Features a qualification test for individual terminations and an application test for terminations already integrated into components. Primary Applications
IEC 60352-5 is a critical reference for several industry roles:
Connector Manufacturers: Use it for product design and global quality validation.
PCB Designers: Refer to it for precise hole dimensions and plating specifications. IEC 60352-5 is the international standard for solderless
Quality Assurance Labs: Follow the standardized testing to ensure consistency across different suppliers and tools.

IEC 60335 is a multipart standard organized as:
The most likely scenario is that you intended to search for IEC 60335-2-5, which is a specific part of the IEC 60335 family. The number "603525" could be a missing hyphen and a misplaced digit.
Alternatively, some users confuse it with IEC 60529 (The IP Code standard), as the digits '3', '5', and '2' often appear in enclosure rating contexts.
Takeaway: Before downloading anything, verify the exact standard number. Using the wrong standard can lead to product non-compliance, failed audits, or safety hazards.
