The Fibre Distributed Data Interface (FDDI) is intended for use in a high-performance general purpose multistation network and is designed for efficient operation with a peak data rate of 100 megabits per second. It uses a token ring architecture. This part of ISO/IEC 9314 extends the basic FDDI by allowing both multimode and single-mode fibre (MMF and SMF respectively) as transmission media. The…

This part of ISO 2884 is one of a series dealing with the sampling and testing of paints, varnishes and related products. It supplements ISO 2431:1993, Paints and varnishes — Determination of flow time by use of flow cups. It specifies the general procedure to be followed in determining the dynamic viscosity of paints, varnishes and related products at a rate of shear between 9 000 s?1 and 12 000…

This Recommendation | International Standard provides for the unique registration of JPEG and SPIFF Profiles, SPIFF Tags, SPIFF colour Spaces, application specific Markers, SPIFF Compression types and images Registration authorities as defined in the CCITT Rec. T.81 | ISO/IEC 10918-1 and ITU-T Rec. T.84 | ISO/IEC 10918-3. Unless otherwise specified, (P)rofiles, (T)ags, colour (S)paces, (M)arkers…

1. Scope 1.1 This guide provides tools to help develop an objective and consistent approach to understanding how your organization can better manage the environmental aspects it controls and over which it has an influence. Suggestions in this guide do not add to the requirements of ISO 14001. Figure 2 shows how your organization's activities, products, and services have the potential…

This International Standard specifies two test methods for determining the refractive index of plastics, namely: Method A: a refractometric method for measuring the refractive index of moulded parts, cast or extruded sheet or film, by means of a refractometer. It is applicable not only to isotropic transparent, translucent, coloured or opaque materials but also to anisotropic materials. The…

Specifies a small-scale laboratory screening procedure for comparing the relative burning behaviour of specimens made from plastics and other non-metallic materials, as well as their resistance to burn-through when exposed to a flame ignition source of 500 W nominal power. This method is applicable to both solid materials and cellular plastic materials having an apparent density of 250 kg/m3 or…

Describes how the concentrations of dissolved gases or free gases may be interpreted to diagnose the condition of oil-filled electrical equipment in service and suggests future action. Applicable to electrical equipment filled with mineral insulating oil and insulated with cellulosic paper or pressboard-based solid insulation. Information about specific types of equipment such as transformers…

1.1 This part of ISO 8257 establishes a system of designation for poly(methyl methacrylate) (PMMA) thermoplastic materials, which may be used as the basis for specifications. 1.2 The types of PMMA plastics are differentiated from each other by the classification system based on appropriate levels of the designatory properties a) Vicat softening temperature, b) melt mass-flow rate, c) viscosity…

1.1 This part of l[SO/lEC 9646 defines an informal test notation, called the Tree and Tabular Combined Notation (TTCN), for OS1 conformance test suites, which is independent of test methods, layers and protocols, and which reflects the abstract testing methodology defined in ISO/IEC 9646-l and ISWIEC 9646-2. 1.2 It also specifies requirements and provides guidance for using TTCN in the…
