SIST EN 168200:2002 + A1:2002

Overview

SIST EN 168200:2002 + A1:2002 is a sectional specification developed by the Slovenski inštitut za standardizacijo (SIST). This standard focuses on quartz crystal units, with specific emphasis on qualification approval processes. Replacing the earlier CECC 68 200 Issue 1:1990, it aligns with European standards for piezoelectric and dielectric devices, and is recognized under the International Classification for Standards (ICS) code 31.140.

Quartz crystal units are widely used in electronic devices for frequency control and timing applications. Ensuring their reliability and consistency through standardized qualification processes is vital for industries relying on precise electronic components.

Key Topics

• Quartz Crystal Units: Definition and specification of the device types covered under this standard, including requirements for construction and electrical characteristics.
• Qualification Approval: Detailed procedures for qualification approval that promote confidence in component reliability through systematic testing and documentation.
• Testing Methods: Outline of test categories and methodologies that manufacturers must follow to validate product performance under various conditions.
• Documentation and Traceability: Guidance on maintaining clear records and traceability throughout each stage of the qualification approval.
• Conformity Assessment: Explanation of how products can demonstrate compliance with relevant national and European quality and performance standards.

Applications

The requirements set by SIST EN 168200:2002 + A1:2002 serve as a framework for multiple industries that depend on quartz technology for accurate frequency generation and stable operation, including:

• Telecommunications: Reliable quartz crystal units are vital for timing and synchronization in communication networks, including cellular and data transmission equipment.
• Consumer Electronics: Used in products such as clocks, watches, radios, and computers, where consistent and precise timing is essential.
• Industrial Automation: Automated control systems and measurement equipment depend on quartz crystals for stable frequency references.
• Automotive Electronics: Support the operation of navigation systems, sensors, and safety systems that require precise timing and coordination.
• Medical Devices: Critical to proper functioning in diagnostic, monitoring, and therapeutic equipment.

Complying with this standard helps manufacturers demonstrate the quality, consistency, and reliability of their quartz crystal units, facilitating market access across Europe and internationally.
