This part of ISO 1833 specifies a method, using sulfuric acid, to determine the mass percentage of chlorofibres and certain other fibres, after removal of non-fibrous material, in textiles made of mixtures of

cotton, viscose, cupro, modal, lyocell, acetate, triacetate, polyamide, polyester, elastomultiester, certain acrylic and certain modacrylic fibreswith

chlorofibres based on homopolymers of vinyl chloride, polypropylene, elastolefin, melamine and polypropylene/polyamide bicomponent.

The modacrylics concerned are those which give a limpid solution when immersed in concentrated sulfuric acid (ρ = 1,84 g/ml at 20°C).]

This method can be used, particularly in place of the methods described in ISO 1833‑12 and ISO 1833‑13, in all cases where a preliminary test shows that the chlorofibres do not dissolve completely either in dimethylformamide or in the azeotropic mixture of carbon disulfide and acetone.

This document specifies the minimum requirements of unused fire-resistant and less flammable hydraulic fluids for hydrostatic and hydrodynamic systems in general industrial applications. It is not intended for use in aerospace or power-generation applications, where different requirements apply. It provides guidance for suppliers and end users of these less hazardous fluids and to the manufacturers of hydraulic equipment in which they are used.

Of the categories covered by ISO 6743‑4, which classifies the different types of fluids used in hydraulic applications, only the following are detailed in this document: HFAE, HFAS, HFB, HFC, HFDR and HFDU.

Types HFAE, HFAS, HFB, HFC and HFDR are “fire-resistant” fluids as defined by ISO 5598. Most HFDU fluids, while displaying an improvement in combustion behaviour over mineral oil, fall outside this definition and are more appropriately considered “less flammable” fluids.

NOTE For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent, respectively, the mass fraction and the volume faction of a materiál.

This document specifies a method, by determining the nitrogen content, to calculate the proportion of each component, after the removal of non-fibrous matter, in textiles made of mixtures of

—    jute

with animal fibres.

The animal-fibre component may consist solely of hair or wool, or of any mixtures of the two.

This part of ISO 1833 is not applicable to products in which dyestuffs or finishes contain nitrogen.

NOTE          Because this method differs in principle from the general method based on selective solubility set out in ISO 1833‑1, it is given in a form that is complete in itself.

This part of ISO 19063 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of PS-I moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given here.

Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize PS-I moulding and extrusion materials are listed.

The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for, or of particular significance to, these moulding and extrusion materials are also included in this part of ISO 19063, as are the designatory properties specified in Part 1.

In order to obtain reproducible and comparable test results, it is necessary to use the methods of specimen preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

This document specifies a method for the assessment of the persistence of a flame applied to the edge of a wick of non-flammable material immersed in fire-resistant fluid. The test relates to the bulk behaviour of a fluid, which may provide pertinent information for safe transportation and storage.

This test does not determine the behaviour of a spray of fire-resistant fluid (see Introduction).

This document establishes one of two basic measures of fire-resistance, and may be called up in regulations governing the use of fire resistant hydraulic fluids under ISO 12922 [1].

This document does not apply to certain water-containing fluids or emulsions that do not adhere to the test board.

This part of ISO XXXX is applicable to all amorphous polystyrene homopolymers.

It applies to materials ready for normal use, unmodified or modified by colorants, additives, fillers, etc.

This part of ISO XXXX does not apply to expanded polystyrene, styrene copolymers, homopolymers of substituted styrene or those modified with other polymers such as elastomers.

It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO XXXX does not provide engineering data, performance data or data on processing conditions which might be required to specify a material for a particular application and/or method of processing.

If such additional properties are required, they shall be determined in accordance with the test methods specified in Part 2 of this International Standard, if suitable.
