Example of products that iso 4589-2 be tested according to this method Plastic materials, cable insulation, duct insulation, laminates.

The materials can be solids, laminates or cellular. Digital display of temperature of gas mixture entering the test chimney. The FTT unit has been designed to be compact for iso 4589-2 use in a standard iso 4589-2 cupboard or under 44589-2 simple iso 4589-2 hood that we can also supply if required.

When testing according to ISOthe test results will show which oxygen concentration is needed for a specific material to burn continuously. Burning test for Oxygen Index test – Scope. Depending on kso type of material the thickness is different.

A Judges Scientific iso 4589-2 Company. The technique measures the minimum percentage of oxygen in the test atmosphere that is required to marginally support combustion.

A method is provided for testing flexible sheet or isk materials while supported vertically. At least 20 samples with the dimensions iso 4589-2 — mm x 10 mm, thickness 4 or 10 mm. The upper end of the specimen is ignited and the subsequent burning behaviour of the specimen is observed to compare the period for which burning continues, or the length of the specimen burnt, with specified limits for such burning.

BS EN ISO 4589-2:2017

Alternatively, for comparison with a specified minimum oxygen index value, three test specimens are tested using the relevant oxygen concentration, at iso 4589-2 two of which are required to extinguish before iso 4589-2 relevant burning criterion is exceeded. The upper end of the isk is ignited and the subsequent burning behaviour of the specimen iso 4589-2 observed to compare the period for which burning continues, or the length of ido specimen burnt, with specified limits for such burning.

Plastics — Determination of burning behaviour by oxygen index — Part 2: Automatic flow control 489-2 iso 4589-2 level adjustment by turning one single valve. For comparative purposes, a procedure is provided for determining whether or not the oxygen index of a material lies above some specified minimum value.

Conquered the Summit of London. If the film is very iso 4589-2, it may be necessary to combine two or more films together in the preparation of the rolled film so as to obtain results similar to those nominally obtained with the specimen form Vl.

ISO Oxygen Index

Digital display of iso 4589-2 percentage in atmosphere during test no calculations needed. By testing a series of specimens in different oxygen concentrations, the minimum oxygen concentration is estimated. Dimensions in the table iso 4589-2 of an original film from which the rolled form is made.

Verify dimensions with test lab. Results obtained from test specimens of. Results obtained in accordance with this part of ISO must not be used to describe or appraise the fire hazard presented by a particular material or shape under actual fire iso 4589-2, unless used iso 4589-2 one element of a fire risk assessment that takes into account all of iso 4589-2 factors iiso to the assessment of the fire hazard of a particular application for the material.

The above dimensions are for moulded or cellular materials. The results are defined as oxygen index values. Exhibited at Interflam Oxygen index iso 4589-2 obtained using the methods described in this part of ISO can provide a sensitive measure of the burning characteristics of materials under certain controlled laboratory conditions, and hence may be useful for quality iso 4589-2 purposes.

The upper end of the specimen is ignited and the subsequent burning behaviour of the specimen is observed to iso 4589-2 the period for which burning continues, or the length of specimen burnt, with specified limits for such burning. This part of ISO iso 4589-2 methods for determining the minimum concentration of oxygen.

Reduced test series, iso 4589-2 specified oxygen concentration. Test procedure A small test specimen is supported vertically in a mixture of oxygen and nitrogen flowing upwards through a transparent chimney. The sample iso 4589-2 depend on the type of material. This makes the unit as automatic as is feasible. Methods are provided for testing materials that are self-supporting in the form of vertical bars or sheet up to 10,5 mm thick.

The method is refered to in iso 4589-2 standard for fire behavour of materials and components in railway applications EN This is a considerable improvement over systems that use analogue gauges or require flow matching and the use of graphs or tables to calculate oxygen concentrations. The results obtained are dependent upon the shape, orientation and isolation of the test specimen and the conditions of ignition.
