3. Test methods
3.1. The linear dimensions of the rollers must be checked using measuring instruments with a permissible error of ± 0.1 mm or a template. The diameter of the bracket and the tolerance of the roundness of the body are checked using measuring instruments with an error of ± 0.1 mm.
3.2. Control for compliance with the requirements given in paragraphs. (in terms of standard samples), (with the exception of the pile height), , , , , - , must be carried out visually - by comparing with a standard sample.
1 - coating sample; 2 - seam
Heck. five
3.3. The quality of the seam (p.) is checked on a 50 mm wide part of this coating cut out from the fur coating. The check is carried out using a general-purpose dynamometer of the 2nd accuracy class by applying a static load for 1 min according to the scheme indicated in Fig. .
Breaking the base of the fur along the seam is not allowed.
3.4. The strength of welded joints for compliance with the requirements of clause is checked using a general-purpose dynamometer of the 2nd accuracy class by applying a static load for 1 min.
3.5. The strength of the connection of the bracket or rod with the handle (p.) is checked on special devices using a general-purpose dynamometer of the 2nd accuracy class by applying a static load for 1 min.
3.6. The quality of the assembly of the rollers in accordance with paragraph. , check by rolling a roller without applying additional effort on a wooden board roughness Rz 500 µm GOST 7016.
The roller roller must rotate freely without slipping, and the coating must remain fixed by the housing and bearing.
