ISO 21632:2018/Amd 1:2020

Overview

ISO 21632:2018/Amd 1:2020 is an important amendment to the international standard governing graphic technology, specifically focusing on the determination of energy consumption in digital printing devices. This amendment enhances the original 2018 ISO 21632 standard by refining measurement methods for energy use, including key transitional and related operational modes of digital printers. Developed by ISO Technical Committee ISO/TC 130, this document helps organizations accurately assess and optimize the energy efficiency of digital printing equipment.

This standard supports environmental sustainability efforts by providing consistent, internationally recognized guidelines for measuring the power usage of digital printing devices during various usage states-from startup and standby to active print modes.

Key Topics

• Energy Consumption Metrics: Defines precise measurement techniques to quantify energy use across different modes of digital printing devices.
• Transitional Modes Measurement: Expands coverage to include transitional states such as print-ready, warm-up, sleep, and recovery modes – critical for realistic energy profiling.
• Updated Definitions: Revises terminology for clarity, such as "digital printing device being measured," to ensure alignment and consistency in implementation.
• Operational Mode Categorization: Introduces detailed categorizations for production printing modes and imposes uniform timing protocols for key phases.
• Energy Calculation Methods: Clarifies calculations including variables such as time duration (in hours) and the number of printed pages for accurate energy assessment.
• Environmental Conditions: Specifies ambient temperature and relative humidity ranges for testing to ensure reproducible and fair comparisons.
• Data Presentation: Updates figures and tables to improve readability and accuracy of energy use data, supporting better decision-making.

Applications

• Digital Printing Equipment Manufacturers: Utilize this standard to design and test printers for energy efficiency, enabling compliance with regulatory and sustainability criteria.
• Energy Auditors and Certification Bodies: Employ the defined methods to validate manufacturer claims or support environmental certifications based on energy consumption.
• Sustainability Programs: Incorporate standard measurements as part of green initiatives to reduce the carbon footprint of printing technologies.
• Fleet Management: Help organizations managing multiple digital printing devices analyze operational costs and energy impacts to optimize usage schedules.
• Research and Development: Guide engineering teams in developing advanced printer models with lower power consumption, targeting transitional modes where energy savings are substantial.

Related Standards

• ISO 21632:2018 – The original standard outlining baseline requirements for measuring energy consumption in digital printing devices.
• IEC standards on energy performance for office equipment, which complement this standard by covering electrical safety and power efficiency.
• ISO 12647 series – Standards dealing with color management and process controls in graphic technology, often integrated with energy efficiency considerations.
• ISO/IEC Directives, Part 1 and Part 2 – Provide procedural and editorial rules that govern the development and maintenance of ISO standards including this amendment.

By adopting ISO 21632:2018/Amd 1:2020, stakeholders in the graphic technology and printing industries gain a crucial tool to quantitatively measure and manage the energy footprint of digital printing devices. This supports global efforts toward energy conservation, cost reduction, and environmentally responsible production methods in the print sector.
