SIST EN 60730-1:2001/A14:2005

Overview

SIST EN 60730-1:2001/A14:2005 is an amendment to the European standard governing automatic electrical controls for household and similar use. Issued by CLC (European Committee for Electrotechnical Standardization) in 2005, this amendment updates Part 1 of the EN 60730 series-focusing on the general requirements for automatic controls used in domestic applications. While SIST EN 60730-1:2001/A14:2005 is now superseded by EN 60730-1:2011, it remains a pivotal reference in the development and testing of electrical control devices to ensure safety, reliability, and performance.

This amendment was specifically prepared to integrate clauses from EN 60730-2-1 as it was proposed for withdrawal, and to adjust limitations and testing protocols relating to thermal characteristics of control components.

Key Topics

• Scope Extension and Harmonization
  The amendment expands and modifies the general requirements of automatic electrical controls, aligning references across related parts of the EN 60730 series and preventing conflicts with the soon-to-be-withdrawn EN 60730-2-1.

• Temperature and Thermal Testing Requirements
  Significant additions (clause 14.Z1) focus on the testing of winding temperatures in electric controls:

  • Controls must undergo rigorous testing where moving parts are locked, and currents inducing maximum permitted temperatures plus specific increments are applied.
  • These tests include multiple cycles of temperature increments followed by humidity treatments to simulate real-world operating conditions.
  • Post-test evaluations require insulation resistance and electric strength tests at reduced voltages to validate durability.

• Insulation Classification Clarification
  Provides guidance on assessing insulation system classifications when unconventional materials or combinations are used, ensuring the insulation system meets declared temperature class ratings.

• Implementation and Compliance Dates
  Mandates that national standards incorporate this amendment by December 1, 2005, with conflicting older standards to be withdrawn by June 1, 2010.

Applications

The provisions of SIST EN 60730-1:2001/A14:2005 apply broadly to automatic electrical controls intended for household and similar environments, such as:

• Thermostats and heating controls in household appliances
• Timers and switching devices controlling lighting or appliances
• Current or voltage sensing relays in home automation systems
• Safety and functional controls embedded in household electrical equipment

The amendment ensures these controls can safely operate under varying temperature conditions, maintain insulation integrity, and meet humidity resistance, directly contributing to consumer safety and product reliability.

Related Standards

• EN 60730-1:2011 – The updated standard that supersedes SIST EN 60730-1:2001/A14:2005, integrating further improvements and harmonization.
• EN 60730-2 Parts – Specific parts of the EN 60730 series addressing particular control functions or device types; part 2-1 was withdrawn to avoid overlap.
• IEC 60730-1 – The international version from which the European standards derive, maintaining global consistency.
• EN 60335-1 – Household and similar electrical appliances - Safety - General requirements, referenced for defining test conditions.

By adhering to SIST EN 60730-1:2001/A14:2005, manufacturers enhance the safety and durability of their automatic electrical controls, ensuring compliance with European regulations and confidence in household electrical device performance. This amendment addresses critical aspects of thermal endurance testing, insulation classification, and environmental resilience, key factors in today's electronics standards.
