Information technology - Open Systems Interconnection - Basic Reference Model:
The Basic Model
The international community has decided to make this standard available only in
the English language version. It has been adopted as a National Standard of
Canada on this basis.
This National Standard of Canada is equivalent to International Standard
ISO/IEC 7498-1:1994.
1. Scope
1.1 The purpose of this Reference Model of Open Systems Interconnection is to
provide a common basis for the…
Foreword
Organizations of all types and sizes are giving increasing attention to establishing systems and procedures that will ensure that their operations are environmentally efficient. They are also considering ways by which the efforts being made in this regard and the results of those efforts can best be communicated to their various audiences. Environmental reporting is still in its…
Information technology — Portable Operating System Interface (POSIX) — Part 2: Shell and Utilities
This part of ISO/IEC 9945 defines a standard source-code-level interface to command interpretation, or "shell," services and common utility programs for applica- tion programs. These services and programs are complementary to those specified by ISO/IEC 9945-1: 1990 (IEEE Std 1003.1-1990) {8}, hereinafter referred to as "POSIX.1 {8}." When the User Portability Utilities Option…

Medical laboratories — Concepts and specifications for the design, development, implementation and u...
The proposed standard document specifies requirements for ensuring quality, safety and performance of laboratory-developed tests (LDT). It outlines the general principles and assessment criteria by which LDT shall be designed, developed, manufactured, validated and monitored for internal use by medical laboratories.
While the proposed standard follows a current best practice and state-of-the art…
Polyethylene (PE) materials for piping systems — Determination of Strain Hardening Modulus in relati...
ISO 18488:2015 specifies a method for the determination of the strain hardening modulus which is used as a measure for the resistance to slow crack growth of polyethylene.
The strain hardening modulus is obtained from stress-strain curves on compression moulded samples. This International Standard describes how such measurement is performed and how the strain hardening modulus shall be determined…
Space Data System Practices — Reference model for an open archival information system (OAIS)
ISO 14721:2012 defines the reference model for an open archival information system (OAIS). An OAIS is an archive, consisting of an organization, which may be part of a larger organization, of people and systems that has accepted the responsibility to preserve information and make it available for a designated community. It meets a set of such responsibilities as defined in this International…
