Detailed Standards Coverage

EN IEC 62301:2026 – Measurement of Standby Power for Appliances and Equipment

Measurement of standby power for appliances and equipment

This standard provides systematic methods to measure the standby and off-mode power consumption of a wide variety of electrical and electronic equipment. It applies to products powered by mains AC, extra low voltage supplies (both AC and DC), or internal batteries, and covers devices ranging from household appliances to IT, audio, video, and multimedia systems.

Building on previous editions, EN IEC 62301:2026 expands its reach, offering greater precision and alignments to current technology trends:

• Expanded Scope: Includes battery- and DC-powered devices, not just AC-powered equipment.
• Rich Definitions: Comprehensive revision and expansion of terms for accurate measurement classifications and reporting.
• Alignment with Other Standards: Explicit distinction between non-active modes (covered here) and networked standby (covered in IEC 63474).
• Improved Measurement Requirements:
  • Enhanced requirements for data logging and test data integrity
  • Removal of older measurement methods in favor of more robust, representative techniques (such as the new moving average method)
  • Clarified conditions for test environments, power measuring instruments, and product setup.

Key product categories:

• Household appliances
• IT, audio, video, multimedia equipment
• Electrical and gas-burning equipment with standby or non-active modes

Practical implications:

Organizations can now benchmark and minimize standby energy, directly supporting both cost reduction goals and regulatory compliance, including energy labeling and eco-design directives. Test labs and manufacturers must ensure their equipment and procedures conform to these updated requirements.

Key highlights:

• Scope expanded to all non-active modes; battery and DC devices included
• Measurement uncertainty and data integrity requirements strengthened
• Alignment and harmonization with terminology across related IEC standards

IEC 63580:2026 – Measuring Equipment for Electrical and Electromagnetic Quantities – Environmental Aspects

Measuring equipment for electrical and electromagnetic quantities - Environmental aspects

IEC 63580:2026 signals a jump forward in environmentally conscious design (ECD) for measuring equipment—a category that includes devices such as PMDs, power quality instruments, transducers, and data management systems. It serves as a vital guide for manufacturers aiming to assess and improve the environmental impacts of their products across the entire lifecycle.

Standard scope and coverage:

The standard is focused on fixed installed measuring equipment, including:

• IEC 61557-12: Power metering and monitoring devices (PMD)
• IEC 62586-1: Power quality instruments (PQI)
• IEC 60688: Transducers (TRD)
• IEC 62974-1: Devices for data management (DDM)

Key requirements and recommendations:

• Life Cycle Assessment (LCA) Rules: Framework for quantifying and reporting environmental impacts at every stage: raw material extraction, manufacturing, use, and end-of-life treatment.
• Product-Specific Rules (PSR): Detailed procedures for each device type, ensuring consistency in how environmental footprint is calculated and communicated.
• Material Efficiency and Declaration: Guidance on materials used, hazardous substance reduction, recyclability, and clear reporting obligations for manufacturers.
• End-of-Life (EOL) Recommendations: Procedures for disassembly, recycling, and minimizing environmental burdens after the product’s working life.
• Alignment with Global Directives: Supports ISO 14040, ISO 14044, and regional programs such as the European Union’s Ecodesign Directive.

Who needs to comply?

• Manufacturers of instruments covered under the outlined IEC series
• B2B customers and procurement officers seeking eco-friendly solutions
• LCA practitioners and verification bodies
• Program operators issuing environmental declarations

Practical implications:

This standard enables manufacturers to meet rising market and regulatory demand for sustainable products. It helps streamline environmental data collection and communication across the supply chain, facilitates Green Public Procurement (GPP), and enhances competitive differentiation.

Key highlights:

• Comprehensive LCA rules and environmental data management
• Standardized communication on product environmental performance
• Rigorously defined end-of-life and material efficiency requirements

ISO/IEC Guide 98-5:2026 – Guide to the Expression of Uncertainty in Measurement — Part 5: Examples

Guide to the expression of uncertainty in measurement — Part 5: Examples

This new guide adds practical depth to the internationally recognized Guide to the Expression of Uncertainty in Measurement (GUM). Part 5 is a robust compilation of real-world examples detailing how to apply the methods and principles from previous parts, making the evaluation and reporting of measurement uncertainty more accessible and actionable.

What does this part provide?

• Hands-on Case Studies: Covering diverse measurements—including chemical, physical, and environmental metrics
