SIST EN 140201:2002

Overview

SIST EN 140201:2002 is a European standard developed by the CLC (European Committee for Electrotechnical Standardization) that provides a blank detail specification for fixed power resistors, specifically at assessment level S. This standard supersedes the earlier CECC 40 201:1981, offering updated requirements and guidance for the design, testing, and quality assurance of fixed power resistors. The document serves as a framework for manufacturers and users to ensure that fixed power resistors meet consistent quality and performance criteria.

Key Topics

• Fixed Power Resistors: The standard focuses on resistors designed to dissipate significant power reliably in electrical and electronic circuits.
• Assessment Level S: This refers to a specific quality assurance level aimed at ensuring high reliability and performance of the components.
• Blank Detail Specification: SIST EN 140201:2002 provides a template format that users can complete with detailed requirements customized to their applications or product lines.
• Supersession: It replaces the older CECC 40 201:1981 standard, reflecting advances in resistor technology and assessment methods.
• Standardization Scope: The document helps unify specifications across European manufacturers and industries, promoting interoperability and quality consistency.

Applications

Fixed power resistors manufactured according to SIST EN 140201:2002 are critical in various industrial and commercial electronic applications where stable and accurate power dissipation is required, including:

• Power supplies and converters
• Electrical load testing equipment
• Control and automation systems
• Consumer electronics requiring reliable heat dissipation
• Industrial machinery and instrumentation

The specification ensures that the resistors deliver performance with predictable tolerance, durability under load, and electrical characteristics compliant with the defined quality levels.

Related Standards

• CECC 40 201:1981 - The earlier standard replaced by SIST EN 140201:2002, which also covered fixed power resistor specifications.
• Other CLC and IEC standards concerning resistor types, testing methods, and environmental durability may complement SIST EN 140201:2002 for comprehensive component assessment.
• SIST EN 140201:2002 - The Slovenian identical adoption of SIST EN 140201:2002, enabling standardized resistor specifications within Slovenia.

By following SIST EN 140201:2002, manufacturers and engineers can ensure that fixed power resistors meet rigorous assessment criteria, enhancing quality, reliability, and international compliance in electronic component production. This standard is essential for anyone involved in the design, production, or application of high-reliability fixed power resistors.
