Information about EN ISO 4589-2 Oxygen Index

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.

Methods are provided for testing materials that are self-supporting in the form of vertical bars or sheet up to 10,5 mm thick.

By testing a series of specimens in different oxygen concentrations, the minimum oxygen concentration is estimated. Verify dimensions with test lab. Alternative size for self supporting moulding or sheet materials, for electrical purposes.

Test procedure A small test specimen is supported vertically in a mixture of oxygen and nitrogen flowing upwards through a transparent chimney. For comparative purposes, a procedure is provided for determining whether or not the oxygen index of a material lies above some specified minimum value. The 4589-22 are defined as oxygen index values. Reduced test series, one specified oxygen concentration. 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.

At least 20 specimens 4589-22 dimensions 80 – mm x 10 mm, thickness 4 – If the film is very thin, 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. Results obtained from test specimens of. Areas of use All types of plastics that are self-supporting and in the form of vertical bars or sheet up to Dimensions in the table are of an original film from which the rolled ieo is made.

Kso upper end of the specimen is ignited and the subsequent iao behaviour of the specimen is observed to compare the period for which burning continues, or the length of specimen burnt, with specified limits for such burning.

ISO Oxygen Index

When testing according to ISOthe test results will show which oxygen jso is needed for a specific material to burn continuously. By testing a series of specimens in different oxygen concentrations, the minimum oxygen concentration is estimated. The materials can be solids, laminates or cellular. By testing a series of specimens in different oxygen concentrations, the minimum oxygen concentration is estimated.

45589-2 particular materials or applications, it may be necessary or appropriate to specify different test conditions. 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 45892, unless used as one element of a fire risk assessment that takes into account all of the factors pertinent to the assessment of the fire hazard of a particular application for the material.

The materials can be solids, laminates or cellular. At least 20 samples with the dimensions 80 — mm x 10 mm, thickness 4 or 10 mm. This part of ISO specifies methods for determining the minimum concentration of oxygen.

Areas of use All types of plastics that are self-supporting and in the form of vertical bars or sheet up to A method is provided for testing flexible sheet or film materials while supported vertically. The sample dimensions depend on the type of material. The results obtained are dependent upon the shape, orientation and isolation of the test specimen and the conditions of ignition.

For flexible film or sheet. Verify with the test lab which thickness applies. Example of products that can be tested according to this method Plastic materials, isl insulation, duct insulation, laminates.

Example of products that can be tested according to this method Plastic material, cable insulation, duct insulation, laminate, printed circuit board.

Test procedure A small test specimen is supported 458-2 in a mixture of oxygen and nitrogen flowing upwards through a transparent chimney. The method is refered to in the standard for fire behavour of materials and components in railway applications EN Burning test for Oxygen Index test – Principle.

Plastics — Determination of burning behaviour by oxygen index — Part 2: Depending on the type of material the thickness is different. Burning 45889-2 for Oxygen Index test – Scope.

Oxygen index results obtained using sio 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 control purposes. The above dimensions are for moulded or cellular materials. Alternatively, for comparison with a specified minimum oxygen index value, three test specimens are tested using the relevant oxygen concentration, at least two of which are required to extinguish before any relevant burning criterion is exceeded.
