What is ISO/IEC 24735 about?
ISO/IEC 24735 discusses about office equipment for IT technology. ISO/IEC 24735 specifies a method for measuring the digital copying productivity of digital copying devices and multifunctional devices with various copying modes. ISO/IEC 24735 allows comparison of the throughput copying rates for a machine operated in various available operating modes (simplex, duplex, size of substrates, 2-up, etc.) and various available digital image processing configurations. ISO/IEC 24735 includes test files, test setup procedures, test procedures, and reporting requirements for digital copying productivity measurements.
Note 1: ISO/IEC 24735 is not intended to be used for devices that are not able to copy on a media size of A4/8,5” × 11”, devices that do not have an ADF, or devices that are not able to collate multiple copies of original prints from a test set.
Note 2: ISO/IEC 24735 is not intended to replace the manufacturer's rated speeds
Note 3: ISO/IEC 24735 is applicable to digital copying devices and multifunctional devices equipped with automatic document feeder (ADF) and collating function.
Note 4: This document is intended to be used for black and white (B&W) as well as colour digital copying devices and multifunctional devices of any underlying marking technology.
Who is ISO/IEC 24735 for?
ISO/IEC 24735 on measuring digital copying productivity is useful for:
- Digital copying device manufacturers
- End consumers
- Digital device copying
Why should you use ISO/IEC 24735?
Many digital copying devices produce copied pages at a different rate than their nominal speed when running with different modes (simplex, duplex, copying quality modes), different substrate grammage, and collating and/or finishing options. The degree to which a reduction in productivity is experienced depends significantly on other parameters of the job stream.
ISO/IEC 24735 provides a general method for measuring productivity when the above-mentioned job stream parameters for digital copying devices are taken into consideration. ISO/IEC 24735 also includes instructions for the creation of test charts. ISO/IEC 24735 allows manufacturers and buyers of digital copying devices to describe the productivity of various digital copying devices with respect to representative office usage.
What’s changed since the last update?
ISO/IEC 24735:2021 supersedes BS ISO/IEC 24735:2012, which is withdrawn.
The main changes compared to the previous edition are as follows:
- ‘Terms and definition’ have been modified to add new definitions and removed definitions of terms not used in the text
- Added “ready delay time” requirement to “test measurement” procedures
- Added Annex D for the procedure to determine the “ready delay time”.
