This document provides the means for understanding the information model of online course, and demonstrates the basic elements and their descriptions. It is the foundation for conceptual understanding of online course and instructional behaviours in online education. This document can be applied to the design and development of online courses, which are supposed to be migrated and shared between…

This document specifies: — the general principles governing the biological evaluation of medical devices within a risk management process; — the general categorization of medical devices based on the nature and duration of their contact with the body; — the evaluation of existing relevant data from all sources; — the identification of gaps in the available data…

ISO 877-1:2009 provides information and general guidance on the selection and use of the methods of exposure to solar radiation described in detail in subsequent parts of ISO 877. These methods of exposure to solar radiation are applicable to plastics materials of all kinds as well as to products and portions of products. It also specifies methods for determining radiant exposure. It does not…

ISO 13916:2017 specifies requirements for the measurement of preheating temperature, interpass temperature and preheat maintenance temperature for fusion welding. ISO 13916:2017 can also be applied as appropriate in the case of other welding processes. ISO 13916:2017 does not cover the measurement of post weld heat treatment temperatures.

The proposal will cover following aspects: - Requirements on penetrations through vacuum vessel, cryostat and building walls. They serve as different level of confinement systems. Superconducting magnets are located between the vacuum vessel and cryostat with the auxiliary systems connecting the magnets with power and coolant supply outside the main building. - Requirements on the shielding…

This part of ISO 7206 specifies a test method for determining short-term deformation of a press-fit acetabular component for total hip joint replacement under specific laboratory conditions. It also defines the conditions of testing so that the important parameters that affect the components are taken into account and it describes how the specimen is set up for testing. The described method is…

ISO 15015:2011 specifies the requirements and test methods for solid flat extruded sheets of impact-modified acrylonitrile-styrene copolymer materials: acrylonitrile-butadiene-styrene (ABS), acrylonitrile-(ethylene-propylene-diene)-styrene (AEPDS) (commonly known as AES) and acrylonitrile-styrene-acrylate (ASA), without fillers or reinforcing materials. This International Standard also applies to…

ISO 17734-1:2013 gives general guidance for the sampling and analysis of airborne isocyanates in workplace air. When amines and aminoisocyanates are suspected to be emitted (e.g. from thermal degradation of PUR), it is recommended that, in addition to isocyanates, the amines and aminoisocyanates in the air are determined, using DBA and ethyl chloroformate as reagents (see ISO 17734-2). The method…
