ISO 15755 Paper and Cardboard, Standard Test for Prediction of Contrasts

EUROLAB laboratory provides testing and compliance services within the scope of ISO 15755 standard. This European standard specifies the test method for the estimation of visible opposites on paper by reflected light. Visual inspection applies to most types of paper and cardboard.

However, paper that is not flat, has a low light weight (Y-value less than 30%), and contains holes can cause particular problems for instrumental techniques. Fluorescent spots will not be detected by the methods described in this European Standard.

The test pieces to be examined should be examined in reflected light. The area of ​​each greater than a certain value and showing the opposite light reflection to the surrounding area of ​​the plate should be estimated. The areas of the opposites are added up and the total area of ​​the opposites is reported as square millimeters (mm²/m²) per square meter of paper.

It is difficult to obtain precision data for visual pollution enumeration due to the subjective nature of the test method. It is a proven fact that reproducibility is unsatisfactory due to differences in personal judgments.
