Foreword
GB/T 2406 "Plastics - Determination of burning behavior by oxygen index" is divided into three parts.
--- Part 1. Guidelines;
--- Part 2. Test at room temperature;
--- Part 3. high-temperature test.
This section GB/T 2406 Part 2. Equivalent to international standards ISO 4589-2.1996 "Plastics oxygen index determination
Burning behavior - Part 2. Test temperature "(English version) and ISO on 2005-01-15 to ISO 4589-2.1996 released a single modification 1.
This section is equivalent translation ISO 4589-2.1996, and ISO on 2005-01-15 to ISO 4589-2.1996 issued amendments 1, technical
Exactly the same content. For ease of use, ISO 4589-2.1996, this section made the following editorial changes.
--- The "ISO 4589 of this part" to "GB/T 2406 this part" or "this part";
--- Remove the ISO 4589-2.1996 foreword, directory;
--- Increase the national standard foreword, directory;
--- For ISO 4589-2.1996 and other international standards referenced in our country it is tantamount to the adoption of a standard, a direct reference to this section
China's national standard instead of the corresponding international standards, and the rest is not tantamount to the adoption of a standard for the international standards in this section are
Referred to directly;
--- ISO 4589 in the note of the serial number removed, with the national standards for the unit to raise Article ID;
--- The ISO amendments placed in Chapter 9 Replace the precision informative annex NA.

Plastics - Determination of burning behavior by oxygen index
Part 2. room temperature test
1 Scope
GB/T 2406 This section describes under specified test conditions, oxygen, nitrogen mixed gas stream, just to maintain the required minimum sample combustion
Determination of the concentration of oxygen, and the result is defined as oxygen index.
This section applies to a sample thickness less than 10.5mm can erect a self-supporting strip or sheet of material. Also applies to an apparent density greater than
100kg/m3 homogeneous solid material, laminate or foam material, and some less than the apparent density of 100kg/m3 foam. and
It provides a test method can be an upright support of sheet material or film.
For comparison, this section also provides a method for determination of oxygen index of a material is higher than a given value.
Oxygen index values obtained by this method, it is possible to provide the material under certain laboratory conditions controlled combustion characteristics of the sensitivity of the scale can be used for quality
Volume control. The results obtained depend on the shape, orientation and thermal insulation and fire conditions specimen. For special materials or for special purposes, to be regulated
Given the different test conditions. The results of different thicknesses and different way to get the ignition can not be compared, but also with other combustion behavior in fire conditions are not
Related.
The results obtained in this section can not be used to describe or assess a specific material or a specific shape under actual fire conditions material presented
The fire risk can only be evaluated as a certain element of fire risk, the evaluation considered the material fire risk in a particular application
All relevant factors of assessment.
Satisfactory results can not be obtained when these methods are used after heating the material exhibits high shrinkage Note. 1. For example. high-oriented film.
Note 2. The foam flame propagation characteristic evaluation density of less than 100kg/m3 with reference to GB/T 8332.
