Agricultural machinery — Endless variable-speed V-belts and groove sections of corresponding pulleys...
This second edition cancels and replaces the first edition (1976). Specifies the main dimensions of V-belts intended for use on agricultural machinery (in particular harvester-thresher machines), together with the grove section of the corresponding fixed- or variable-diameter pulleys. Tabulates nominal values of datum length from 630 mm up to and including 5 000 mm. Some figures illustrate shapes…
Packaging — Conditioning for testing — Part 1: Paper sacks
The principle consists in exposure of empty sacks to a conditioning atmosphere so that a state of temperature and moisture content equilibrium is reached between the sacks and this atmosphere. Conditioning atmospheres ar described by a table. Equipment, procedure and test report are specified.
Non-destructive testing — Qualification of radiographic film digitisation systems — Part 2: Minimum ...
This document specifies three film-digitisation quality classes for the requirements of non-destructive testing. The selected class depends on the radiation energy, the material thickness penetrated and the quality level of the original radiographic film. This document does not address signal processing, display and storage of the digitised data.
