IEC 60695-1-10:2009

Overview

IEC 60695-1-10:2009 is an internationally recognized standard developed by the International Electrotechnical Commission (IEC) that provides general guidance for assessing the fire hazard of electrotechnical products. This standard is a part of the IEC 60695 series, focusing on fire hazard testing. It is intended to help reduce the risk of fire and mitigate its potential effects involving electrical and electronic equipment.

Designed primarily for use by IEC technical committees, this standard serves as a foundational safety publication to guide the development of fire hazard assessment methods and supports the creation of technically sound fire test procedures relevant to electrotechnical products. It complements the IEC 60695-1-11 guidance on fire hazard assessment and aligns with IEC and ISO safety publication principles.

Key Topics

• Fire Hazard and Fire Risk: Defines the relationship between the physical conditions causing fire hazards and the calculated risk, which combines the probability of fire occurrence and potential consequences.
• Scenario Approach: Emphasizes the importance of assessing fire hazards within the context of realistic scenarios including end-use conditions and foreseeable abnormal uses, ensuring meaningful risk evaluations.
• Fire Testing Methods:
  • Qualitative Fire Tests: Pass/fail or classification-based tests that categorize fire behaviour but may not provide detailed scientific data.
  • Quantitative Fire Tests: Tests designed to measure fire effects with scientific precision, correlating test outcomes with real-world hazards such as heat, smoke, toxic or corrosive combustion products.
• Guidance for Product Committees: Offers criteria to decide when to maintain or develop qualitative versus quantitative fire test methods for electrotechnical products.
• Fire Scales and Test Sizes:
  • Intermediate-scale fire tests (specimens 1 m to 3 m)
  • Large-scale fire tests (specimens larger than 3 m)
• Definitions and Terminology: Provides standardized terms such as fire, fire hazard, fire risk, fire-safety engineering, fire scenario, and types of fire tests for consistent understanding.

Applications

IEC 60695-1-10:2009 is essential for manufacturers, testing laboratories, safety engineers, and regulatory bodies involved in the design, evaluation, and certification of electrical and electronic products with respect to fire safety. Key applications include:

• Product Design & Development: Integrate fire hazard reduction strategies by considering ignition prevention and containment of fire within product enclosures.
• Material Selection: Choose materials that minimize flame spread and reduce the production of harmful combustion effluents.
• Fire Risk Assessment: Utilize the scenario approach to evaluate product performance under normal and abnormal conditions, enabling objective risk management.
• Test Method Development: Develop, maintain, or select appropriate qualitative and quantitative fire test methods tailored to specific electrotechnical products and their use environments.
• Standards Preparation: Assist technical committees in preparing harmonized IEC standards incorporating sound fire hazard assessment principles in line with IEC Guide 104 and ISO/IEC Guide 51.
• Compliance & Certification Support: Facilitate the creation of testing protocols that support conformity assessment and regulatory compliance for fire safety.
