BS EN ISO 4589-2: 1999
Test Details
Purpose of test
To assess the performance of a material when it is tested in accordance with BS
EN ISO 4589 - 2: 1999 "Plastics - Determination of burning behaviour by oxygen
index”.
The test was performed in accordance with the procedure specified in BS EN
ISO 4589-2:1999 - Plastics -
Determination of burning behaviour by oxygen
index
, and this report should be read in conjunction with that BS EN ISO
Standard.
Scope of test
BS EN ISO 4589 – 2: 1999 specifies test methods for determining the minimum
concentration of oxygen, in a mixture with nitrogen that will support combustion
of small vertical test specimens under specified test conditions. The results are
defined as oxygen index values.
Instruction to test
The test was conducted on the 11
th
February 2016 at the request of the original
sponsor of the test.
Provision of test
specimens
The specimens were supplied by the original sponsor of the test. Exova
Warringtonfire was not involved in any selection or sampling procedure.
Conditioning of
specimens
The specimens were received on the 23
rd
January 2016.
Prior to test the specimens were conditioned to equilibrium with air at 23 ± 2
0
C
and a relative humidity of 50 ± 5 per cent for at least 88 hours.
Method of testing
Specimens measuring nominally 100mm long by 6.70mm wide by 2.89mm thick
were used. The thickness of the specimens used conforms with the requirements
specified in Table 2 of the standard for test specimen Form IV for alternative size
for self supporting moulding or sheet material, for electrical purposes. The
specimens were tested in accordance with the test procedure specified in Clause
8 of the Standard using the Concept Equipment
Limiting Oxygen Index
apparatus.
Ignition procedure
Ignition procedure A - top surface ignition, was used to initiate burning on the top
surface of the upper end of the specimen.
