Belt drives — Classical and narrow V-belts — Grooved pulleys (system based on datum width)
Käsitlusala:
This document specifies the principal dimensions of grooved pulleys for classical V-belts (sections Y, Z, A, B, C, D, and E) and narrow V-belts (sections SPZ, SPA, SPB, and SPC) specified in the terminology system based on datum width.

Plain bearings — Testing of the tribological behaviour of bearing materials — Part 2: Testing of polymer-based bearing materials
Käsitlusala:
This document specifies tribological tests of polymer-based plain bearing materials under specified working conditions, i.e. load, sliding velocity and temperature, with and without lubrication. From the test results, data are obtained which indicate the relative tribological behaviour of metal-polymer and polymer-polymer rubbing parts.
The purpose of this document is to obtain, for polymer material combinations used in plain bearings, reproducible measured values for friction and wear under specified and exactly-defined test conditions without lubrication (dry surfaces) and with lubrication (boundary lubrication).

Belt drives -- Classical and narrow V-belts -- Grooved pulleys (system based on datum width)
Käsitlusala:
Cancels and replaces the second edition (1989). Specifies the principal dimensions of grooved pulleys for classical V-belts and narrow V-belts specified in the terminology system based on datum width. It is important that narrow belts are not used with pulleys uniquely designed for classical belts, and, on the other hand, that multiple belt drives are not used with joined V-belts.

Safety of machinery - Safety-related sensors used for the protection of persons
Käsitlusala:
This document set out the requirements for the development and integration of safety-related sensors (3.3.14) (SRS ) and safety-related sensor systems (3.3.15) (SRSS ) used for the protection of persons with particular attention to systematic capability (3.1.4).
This generic product standard applies if protection of persons is to be performed by using sensors.
NOTE 1 The appliance and relationship of this generic product standard with standards on functional safety of safety-related control systems and product specific standards is described in Annex A.
This generic product standard can be applied also for other protective goals like protection of the environment or prevent production goods damages.
The examination of detection capability (3.1.6) as part of the systematic capability (3.1.4) using different product standards is described in Annex A.
The requirements and methods set out in this document are intended for the purpose of protection of persons by:
– detection (3.1.5) of potentially hazardous objects;
– detection (3.1.5) of a body, parts of a body and objects associated to parts of a body entering a hazardous area; or
– classification and/or discrimination of these against other objects.
NOTE 2 The application of SRS/SRSS in a public setting can require the detection (3.1.5) of not only persons, but also their associated equipment, such as wheelchairs, walking sticks or infusion stands.
Performance classes of SRS/SRSS are defined in accordance with existing standards on functional safety of safety-related control systems (e.g. IEC 62061, IEC 61508 (all parts), and ISO 13849 (all parts)).
NOTE 3 By correlating to existing PL or SIL, we have achieved simplification for end users.
Specific attention is devoted to the evaluation of the detection capability (3.1.6) and dependability (3.2.2) of the detection capability (3.1.6) . Environmental conditions and limits for indoor and outdoor use are defined that influence the sensing function and the dependability (3.2.2) of the detection capability (3.1.6).
NOTE 4 Environmental influences, their classification and test (3.7.10) procedures are primarily specified in accordance with generic environmental standards. In the absence of respective standards, more specific requirements and tests are described.
This document can be relevant for applications other than the protection of persons in industry (3.3.17), such as agriculture or public transportation (e.g. metro stations).
This document does not consider or address proven in-use (e.g. processes or elements) as defined in IEC 61508-2 [2].
