Arcand, Jr CG. The bottom ignition oxygen index test. Text. Res. J. 1972 42 328-330. [Pg.416]

The tested material is characterized by the ignition response index (IRI) as follows ... [Pg.146]

The oxygen index results have already been presented in Figure 62.. Results for the same fillers in the ISO ignitability test are presented in Figure 6.4. This shows the coarsest fillers to have very little effect in this test, while the finest has a very dramatic effect. [Pg.281]

Rychly and Pavlinec have developed a method for analysing thermo-gravimetric data for multi-step processes obtained under non-isothermal conditions to provide kinetic data for each step [38]. Rychly and co-workers have applied this and other methods to a detailed study of the flame retardant effects of fillers [36]. In addition to the oxygen index, they used an ignition test based on an adapted thermal analysis method to assess flammability. [Pg.287]

All the standards of polymer combustibility can be subdivided into five major types 1. Ignitability tests 2. Flame spread tests 3. Oxygen index 4. Heat release tests 5. Smoke tests. [Pg.33]

The UL flammability ratings describe the relative ease of ignition and combustibiUty of plastics. Tests include the measurement of flame propagation, time to self-extinguish, melt and drip with and without flame, and oxygen indexes. Some engineering plastics, eg, polyetherimides, are, as ranked by this test, inherently nonflammable. Others can be made nonflammable by compounding with flame retardants (ERs) such as bromine... [Pg.264]

The oxygen index method was used to demonstrate synergy. This method measures ease of ignition, that is the facility with which a material or it s pyrolysis products can be ignited under given conditions of temperature and oxygen concentration. This test is indicative of the intrinsic flamability of a material but... [Pg.344]

One of the most useful laboratory flammability tests is the oxygen index (OI) test (ASTM-D2043). In this test, the specimen is burned as a candle in controlled mixtures of oxygen and nitrogen. The minimum oxygen concentration which produces downward flame propagation is considered the OI of ignitability for the polymer. [Pg.44]
