ISO IEC 17991:2021 pdf download.Information technology — Office equipment — Method for measuring scanning productivity of digital scanning devices
1 Scope
This document specifies a method for determining scanning productivity by measuring “scanning speed”, “scan to network folder speed” and “scan to PC speed”. It includes test files, test setup procedure, test procedure and the reporting requirements for the scanning productivity measurements. This document is applicable to scanning devices including but not limited to multi-function devices, networked scanners and single-function scanners of any underlying scanning technology. This document is applicable to devices which are able to scan a media size of A4/8,5″ × 11″ and which have an automatic document feeder (ADF). It is also applicable to devices which have the ability to scan to network folder, or folder on PC and do not require, but can use, other application programs on a computer or another device to perform a scanning job. This document does not apply to testing and measurement of scan to USB, scan to local hard drive or other storage medium that is part of or plugged into the scanner. This document is not intended to be used for image quality measurement, document or record management of any scanned images.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: — ISO Online browsing platform: available at https://www.iso .org/obp — IEC Electropedia: available at http://www.electropedia .org/ 3.1 ADF speed rate at which a device scans documents using an automatic document feeder (ADF) to demonstrate the productivity of the ADF and is represented with suffix A EXAMPLE scEFTP 1setA is the scanner effective throughput ( 3.3) of the ADF on the 1set test.3.2 duplex duplex scanning use of a scanning device with the scanning being done for both sides of a sheet Note 1 to entry: An equivalent term is “double sided scanning ”. 3.3 scEFTP effective throughput rate at which a device scans pages measured from the initiation of the job through the full ejection of the last page of the scanning sets or through the complete creation of the file on the shared network folder or PC after the transfer of the last page of the last test set (3.16) EXAMPLE scEFTP 1setA means scanning effective throughput of “1 set test ” for “ADF productivity measurement ”. Note 1 to entry: “sc ” denotes that the measurement is taken on the scanner. Note 2 to entry: There are suffixes such as “ 1setA ”, “ 30secF ” or “ 30secP ”. Each suffix is used to classify tests such as “1 set test ” or “1 set + 30 second test ” of the objects of tests for “ADF productivity measurement ” (using suffix A), “scan to network folder productivity measurement ”(using suffix F) or “scan to pc file productivity measurement ” (using suffix P) test respectively.Note 3 to entry: scEFTP is expressed in images per minute (ipm); it can be affected by scan time, digital processing time, maintenance and the run time of the test. Note 4 to entry: A different term ( “EFTP; effective throughput ” for digital copying machines) is defined in ISO/IEC 24735. Note 5 to entry: As for scEFTP 30secF , measurement parameters involving the measurement of file transmission to a network folder are dependent on other factors like the computer and network configuration and represent relative values and not absolute values. Note 6 to entry: As for scEFTP 30secP , measurement parameters involving the measurement of file transmission to a file are dependent on other factors like the computer, IO connection, IO speed and represent relative values and not absolute values. 3.4 scESAT estimated saturated throughput rate at which a device scans pages measured from full ejection of the last page of the first test set (3.16) from ADF through the full ejection of the last page of the last test set (using suffix A) Note 1 to entry: “sc ” denotes that the measurement is taken on the scanner.
