EN 168200:1993/A1:1993

Overview

EN 168200:1993/A1:1993 is a sectional specification for quartz crystal units (qualification approval). It provides a framework for assessing and approving quartz crystal components used in electronic timing and RF equipment. This standard is indexed under ICS 31.140 (Piezoelectric and dielectric devices) and has been adopted in national collections (SIST EN 168200:2002 + A1:2002). The document supersedes CECC 68 200 Issue 1:1990; note that CLC/TC 49 has been disbanded.

Key Topics

• Scope and classification: Defines the sectional scope for quartz crystal units subject to qualification approval.
• Qualification approval process: Describes the purpose and role of qualification approval to demonstrate product conformity and consistency.
• Documentation and marking: Requirements for documentation, marking and traceability that support quality control and procurement.
• Inspection and acceptance: Outlines inspection, test and quality assurance principles used to accept batches or families of crystal units.
• Conformity and certification: Guidance on demonstrating compliance with the sectional specification and on using the approval in procurement and supply chains.

Applications

This standard is practical for organizations involved in the design, manufacture, procurement and testing of quartz crystal units. Typical applications include:

• Timing components for consumer and industrial electronics
• Oscillators and frequency-control modules
• RF components in communication systems
• Sensors and piezoelectric devices where crystal stability and qualification are critical

Adopting the sectional specification helps manufacturers and test laboratories reduce risk by establishing uniform qualification criteria, improving interchangeability and supporting regulatory or customer-driven quality demands.

Related Standards

• CECC 68 200 Issue 1:1990 - superseded by EN 168200
• SIST EN 168200:2002 + A1:2002 - national adoption reference
• ICS 31.140 - classification for piezoelectric and dielectric devices

Practical Value

For procurement managers, product engineers and quality assurance teams, EN 168200:1993/A1:1993 provides a recognized basis for:

• Specifying qualification requirements in contracts and tenders
• Structuring supplier evaluation and approval programs
• Aligning test and inspection practices with a European sectional specification

Use this specification as a reference point when defining acceptance criteria for quartz crystal units and when seeking qualification approval evidence from suppliers.
