Imaging materials. Photographic film. Determination of folding endurance1 Scope This International Standard specifies a method for determining and quantitatively expressing the folding endurance of photographic film. The method is based on the MIT folding endurance tester described in annex B. It is an analytical test and is not intended to simulate practical use conditions. This International Standard is applicable to film with or without a gelatin backing. It may also be applied to either raw or processed film, although

The test consists of breaking by one blow from a swinging pendulum

and validation of equipment after installation

General design rules relevant specifically to buildings

predominantly for the 3rd and 5th harmonic currents

When used with the other specified methodologies

IEC 60942:1988 and IEC 61260:1995

this document is applicable to oriented PVC-O fittings intended to be used for the following:

To conclude

NOTE 1 The approach to description of soil and rock set out in EN ISO 14688-1 and EN ISO 14689 respectively and the approach to classification of soil set out in EN ISO 14688-2 are applicable to earthworks

In order to assist the designer and help facilitate the assessment of achieved PL
