Applies 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 Connectionless-mode Network Service. Profiles of the Connection-mode Transport Service over Connectionless-mode Network Service are members of a single group, Group TA, and…

Covers the taxonomy elements identified as "TA" in the Directory of Profiles and ISPs contained in ISO/IEC TR 10000-2. These elements constitute Transport profiles, group A: Connection-mode Transport Service over Connectionless-mode Network Service. Specifies requirements for the profile identified in ISO/IEC TR 10000 as TA51. The complete set of requirements for TA51 consists of the…

Three levels are given in such a way as to permit application for a wide range of welded fabrications. The levels refer to production quality and not to the fitness-for-purpose of the product manufactured. Annex A gives additional information and guidelines for use of this standard.

The method is based on preparation of test samples and heavy metals standard solutions, preconditioning them, addition of sodium sulfide solution (for determination of heavy metals) or 1,10-phenanthroline reagent (for determination of iron), dilution with water, mixing well, transfer to two Nessler colour-comparison cylinders, and comparing the colour of both solutions.

The method is based on weighing the test portion, dissolution in water, transfer of a 20 ml aliquot in a beaker, pipetting halide standard A or B into a second beaker, adding nitric acid solution plus silver nitrate solution to each beaker, dilution with water, transfer of the treated solutions into separate Nessler colour-comparison cylinders, and observing the turbidity of the two solutions.

The method is based on weighing a test portion, dissolution in water, transfer to one of the Nessler colour-comparison cylinders, pipetting the volume of sulfide standard into the second Nessler colour-comparison cylinder, addition of alkaline lead solution, making up with water, mixing thoroughly, and comparing the colour and clarity of the two solutions.

Establishes rules for the preparation: preliminary work (needs analysis, target group, subject delimitation, sources, number of concepts, choice of languages, schedule) and working procedure (collecting and recording terminological data, establishing the term list, concept fields and concept systems, formulating definitions, coining and selecting terms), as well as for the terminography (…

Specifies criteria for reagents and materials, and addresses a number of general and common aspects involved in performing the tests given in subsequent parts of the standard. Annex A provides an index of International Standards on the specification of photographic-grade chemicals.
