Accuracy (trueness and precision) of measurement methods and results — Part 3: Intermediate measures...
Specifies four intermediate measures due to changes in observation conditions (time, calibration, operator and equipment) within a laboratory. These intermediate measures can be established by an experiment within a specific laboratory or by an interlaboratory experiment. Furthermore, discusses the implications of the definitions of intermediate precision measures, presents guidance on the…

Applicable to End Systems concerned with operating in the Open Systems Interconnection (OSI) environment. Specifies a combination of OSI standards, which collectively provide the connection-mode Transport Service using the connection-mode Network Service. Specifies subnetwork-type dependent requirements applicable to an end system attached to a local area network (LAN) subnetwork and using the…
Information technology — Open Systems Interconnection — Presentation service definition
Defines in an abstract way the externally visible service provided by the OSI presentation layer in terms of the primitive actions and events at the user/service boundary, the parameter data associated with each primitive action and event, the relationship between, and the valid sequences of, those actions and events. The service defined is the connection-oriented service which is provided by the…
