Provide utility program interfaces, service interfaces, managed object definitions, and a standard software packaging layout. Interfaces allow administrators to maintain software products. The managed-object classes provide a common base for the definition and implementation of software administration applications, especially in a distributed environment. The base document for the work is a specification from HP, with reference material drawn from DEC, USL, SNI, ICL, IBM, and SCO.

This standard establishes the minimum performance criteria for portable radiation protection instrumentation for use in ionizing radiation fields under both normal and extreme environmental conditions, i.e., all environmental conditions. For the portable radiation detection instrumentation addressed in this standard, the radiological ranges for the performance tests are as follows: the dose rate range of operation taken as background to 10 Gy/h (1000 rad/h); the activity-per-unit-area range for… read more surface contamination monitors taken as 0.01 Bq/cm (60 dpm/100 cm) or 0.05 Bq/cm (300 dpm/100 cm) to 200 Bq/cm (1.2 × 10 dpm/100 cm). The testing methods verify that the performance criteria are met over the range of operating conditions for each type of instrumentation. This standard does not specify which instruments or systems are required, nor does it consider the number of specific applications of such instruments. read less

This standard defines extensions to POSIX.1 {2} to support application portability at the source-code level. It is intended to be used by both application developers and system implementers. The scope of this standard is to define a portable application interface for applications with realtime constraints requiring the ability to control special devices from the application itself. The intent is to take existing realtime operating system practice and add it to the POSIX family of standards.… read more Specifically within the scope is to define interfaces which do not preclude high-performance implementations on traditional uniprocessor realtime systems, as well as on multiprocessors. Wherever possible, the requirements of other application environments were included in the interface definition. read less

This standard defines the general requirements and test methods for measuring conformance to ISO/IEC 9945-1 :1990 (IEEE Std 1003.1-1990) hereinafter referred to as "POSIX.1" {3}.1 It also defines the test assertions for measuring conformance to POSIX.1 {3}. This standard is intended for use by --Developers of POSIX.1 {3} test methods; --Implementors of POSIX.1 {3} implementations; --Application writers for POSIX.1 {3} conforming implementations; --POSIX.1 {3} testing laboratories; and --Otheres… read more interested in validating the conformance of a vendor-claimed POSIX.1 {3} implementation The purpose of this standard is to specify the test assertions and related test methods for measuring conformance of an implementation to POSIX.1 {3}. Testing conformance of an implementation to a standard includes testing the claimed capabilities and behavior of the implementation with respect to the conformance requirements of the standard. These test methods are intended to provide a reasonable, practical assurance that the implementation conforms to the standard. Use of these test methods will not guarantee conformance of an implementation to POSIX.1 {3}; that normally would require exhaustive testing, which is impractical for both technical and economic reasons. The technical specifications for a POSIX System Application Program Interface are defined in POSIX.1 {3}. IEEE Std 2003.1-1992 defines a means of measuring conformance to the POSIX.1 {3} technical specifications. Any question of interpretation of those technical specifications arising from the use of this standard is a question of interpretation of POSIX.1 {3}. read less
