Over deze norm
1.1.1 The intent of this standard is to provide general guidelines for the design, selection, quality assurance, installation, operation, and maintenance of mechanical drive systems used in remote hot cell environments. The term mechanical drive systems used herein, encompasses all individual components used for imparting motion to equipment systems, subsystems, assemblies, and other components. It also includes complete positioning systems and individual units that provide motive power and any position indicators necessary to monitor the motion.
1.2.1 This standard is intended to be applicable to equipment used under one or more of the following conditions:
188.8.131.52 The materials handled or processed constitute a significant radiation hazard to man or to the environment.
184.108.40.206 The equipment will generally be used over a long-term life cycle (for example, in excess of two years), but equipment intended for use over a shorter life cycle is not excluded.
220.127.116.11 The equipment can neither be accessed directly for purposes of operation or maintenance, nor can the equipment be viewed directly, for example, without radiation shielding windows, periscopes, or a video monitoring system (Guides C1572 and C1661).
1.2.2 The system of units employed in this standard is the metric unit, also known as SI Units, which are commonly used for International Systems, and defined, by Standard for Use of International System of Units. Common nomenclature for specifying some terms; specifically horsepower uses a combination of both metric and inch-pound units.
1.3 User Caveats:
1.3.1 This standard is not a substitute for applied engineering skills, proven practices and experience. Its purpose is to provide guidance.
18.104.22.168 The guidance set forth in this standard relating to design of equipment is intended only to alert designers and engineers to those features, conditions, and procedures that have been found necessary or highly desirable to the design, selection, operation and maintenance of mechanical drive systems for the subject service conditions.
22.214.171.124 The guidance set forth results from discoveries of conditions, practices, features, or lack of features that were found to be sources of operational or maintenance problems, or causes of failure.
1.3.2 This standard does not supersede federal or state regulations, or both, and codes applicable to equipment under any conditions.
1.3.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
