| 1.7 | Additional details on paper faces. | Paper's face and reverse side may feature additional details and information. These additional details and information may not interfere with the legibility of the printouts.Visual inspection. | 136 | 2. Storage Tests |
Printout legibility is assured if optical densities comply with the following limits:
Printed characters: min. 1,0 Background (unprinted paper): max. 0,2 Printouts shall be produced on paper before the end of its shelf-life. Environmental conditions (temperature, relative humidity) during printout production shall be recorded.
Printouts shall be subjected to pre-conditioning, before exposure to the test environment. After exposure to the test environment, printouts shall be subjected to recovery conditions, before measurement of optical densities according to DIN EN ISO 534. Printouts shall show no dimensional changes and remain clearly legible.

Legibility criteria
Printout legibility is assured if optical densities comply with the following limits:
Printed characters: min. 1,0
Background (unprinted paper): max. 0,2
Paper, before the end of its shelf-life, shall be subjected to
environmental tests simulating service conditions. Printouts shall be
produced on this paper after exposure to the simulated service
conditions. Specification of the simulated service conditions defines
three phases: preconditioning, test environment, recovery conditions.
Printouts are produced on completion of the recovery phase. Optical
densities of the resulting printouts shall be measured according to DIN
EN ISO 534.
Printouts shall show no dimensional changes and remain clearly legible.
Fastness tests to liquids such as water, oil, petrol, diesel, etc,
shall be specified in a subsequent version of this document.
