ISO IEC 15404 pdf download Information technology — Office machines — Minimum information to be included in specification sheets — Facsimile equipment
1 Scope
This International Standard is intended to facilitate the users in selecting facsimile equipment which meets theirrequirements.
This International Standard specifies the minimum information that shall be included in the specification sheets offacsimile equipment so that users may compare the characteristics of different machines.
This International Standard applies to facsimile equipment that could be operated in an office environment.Facsimile equipment requiring specially equipped rooms or specially instructed operators are not considered in thisInternational Standard. Facsimile equipment is assigned to group 3 and 4 depending on technical capabilities andis classified according to paper handling, scanning, recording and resolution.

Conformance
In order to comply with this International Standard, specification sheets shall contain, in the order shown all temslisted in clause 4 which are relevant to the machine being described.
4 Environmental conditions
Unless otherwise specified, all tests and measurements shall be conducted at the following conditions:
temperature: 1 8 °C to 25 °C
relative humidity: 30 % to 70 %
voltage: rated input voltage
frequency: rated frequency
paper size: A4
paper weight: 60 g/m 2 to 90 g/m 2
Whenever a capacity is given in sheets, the reference paper weight shall be specified.
When A4 paper size is specified, the size most commonly used in the country can be used, both for the test page and the copies. This shall be indicated in the specification sheet.
When weight of paper (g/m 2 ) is given, it is assumed that the paper has been conditioned in the standard atmosphere defined in ISO 554 (temperature 20 °C ? 2 °C; relative humidity 65 % ? 5 %).
