4.1 This guide has three purposes:4.1.1 To serve as a guide for developers of computer software that provides or makes use of authentication and authorization processes,4.1.2 To serve as a guide to healthcare providers who are implementing authentication and authorization mechanisms, and4.1.3 To be a consensus standard on the design, implementation, and use of authentication and authorization mechanisms.4.2 Additional standards will define interoperable protocols and message formats that can be used to implement these mechanisms in a distributed environment, using specific commercial technologies such as digital signatures.1.1 This guide covers mechanisms that may be used to authenticate healthcare information (both administrative and clinical) users to computer systems, as well as mechanisms to authorize particular actions by users. These actions may include access to healthcare information documents, as well as specific operations on those documents (for example, review by a physician).1.2 This guide addresses both centralized and distributed environments, by defining the requirements that a single system shall meet and the kinds of information which shall be transmitted between systems to provide distributed authentication and authorization services.1.3 This guide addresses the technical specifications for how to perform user authentication and authorization. The actual definition of who can access what is based on organizational policy.
5.1 The user-level calibration process may be used to verify that the DF tester is functioning properly, that it is within manufacturer specifications, and to perform minor adjustments to bring the unit back into conformance with manufacturer specifications.5.2 The DF tester user-level calibration described herein does not eliminate all error sources, nor does it guarantee the proper operation of the device. Several adjustments and repairs are beyond the scope of this standard, and manufacturer-approved calibrations are still recommended on an annual basis.1.1 This test method describes the equipment and procedure to ensure that the calibration performed by various dynamic friction tester (DF tester) users is uniform and in accordance with manufacturer specifications. There are three models of the DF tester in use: (1) USB/personal computer, (2) controller, and (3) X-Y plotter. Procedures specific to the different models are noted. User-level calibration software is separate from the operation software and must be obtained from the manufacturer for the USB/personal computer model.1.2 This test method is a static calibration of the vertical load, friction (µ) force, and speed of the DF tester. Compliance to this user-level calibration procedure ensures a higher level of repeatable and reproducible performance of the DF tester when used in accordance with Test Method E1911.1.3 The user-level calibration doesn’t include the replacement of the mu spring or the adjustment of linearity of the DF tester. It is recommended that DF testers be inspected by a manufacturer-approved laboratory on an annual basis to replace the mu spring, ensure linearity, and to identify other non user-serviceable wear.1.4 The values stated in SI (metric) units are to be regarded as standard. The inch-pound equivalents are rationalized, rather than exact mathematical conversions.1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
