    The performance of various testing columns in small-scale horizontal burning studies (1984)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The use of Critical Oxygen Index testing columns in the horizontal configuration is investigated. Gas analysis results from within columns of simple design indicate that they are unsuitable for burning studies because of entrainment of the external atmosphere and recirculation of combustion products. A new design of column and holder is proposed that eliminates these effects and provides a possible means of studying small-scale horizontal combustion in different oxygen/nitrogen mixtures.

    Factors that influence the critical oxygen index of various solids (1979)

    Notes: The Critical Oxygen Index test has been used as a measure of the flammability of a wide range of substances, including plastics, textiles and liquids, since its introduction in 1966. The index, however, is only appropriate to the configuration and conditions used in the test, and extrapolation in order to predict the flammability of materials in a large-scale fire is not valid. The index is dependent on a number of sample and test parameters and these are reviewed; the ASTM test standard, the reproducibility of the results, and certain theoretical aspects are also discussed.

    Notes: The dependence of the Critical Oxygen Index values of some thermoplastic materials on sample sixe is reported. The extent of melting of this class of material is shown to be important in determining the effect of sample size on the index.

    Correlation between the critical oxygen index test and other fire tests (1981)

    Notes: The Critical Oxygen Index test is widely used as a measure of the flammability of many substances. This paper reviews attempts that have been made to compare Oxygen Index values with the results from other fire tests. Varying degrees of correlation are apparent, depending on the properties being measured in the respective tests.

    Anomalous behaviour in certain versions of the critical oxygen index test (1981)

    Notes: Measured Critical Oxygen Index values at 40°C for Opal polymethylmethacrylate (Perspex) sheet have been found to be remarkably dependent on the gas velocity within the column of the Hot Flammability Test Apparatus. Investigation of the atmosphere present in the column has indicated that the effect is almost solely attributable to varying quantities of ambient air entering the column as the flow rate is altered. A modification to the apparatus is proposed that successfully prevents this entrainment of air at normal testing flow rates.

    Identification of two pass regimes for nylon-66 based rods in the critical oxygen index testCorrected proofs received June 28, 1982 (1982)

    Notes: Critical Oxygen Index (COI) values for rods of a nylon-66 based material of various diameters have been determined at 40°C. The existence of two discrete COI values has been identified for many sizes above a critical diameter: the two indexes correspond to clean burning and to burning with melting and dripping. The difference between the two indexes is dependent on rod diameter and can be greater than five units.

    Die Kinetik und der Mechanismus der Reduktion zweier isomerer μ-Cyanobenzoato-di-μ-hydroxo-bis [triamminkobalt(III)] Komplexe mit Chrom(II) und Vanadin(II) (1976)

    Description / Table of Contents: Kinetics and Mechanisms of the Reductions of Two Isomeric μ-Cyanobenzoato-di-μ-hydroxo-bis[triamminecobalt(III)] Complexes by CrII and VIIThe Cr2+ and V2+ reductions of the binuclear μ-3-cyanobenzoato-di-μ-hydroxo-bis[triamminecobalt(III)] and its μ-4-cyanobenzoato analog have been studied by conventional spectrophotometric methods at 25°C, I = 1.0 M (LiClO4). The reactions are first order in oxidant and reductant, and independent of acid ([H+] = 0.04-0.97 M). Reduction of the first cobalt is rate determining. Outersphere mechanisms for all reductions are assigned on the basis of kCr : kV ratios (∼0.02). The non capacity of cyanobenzoic acids to mediate electrons via an innersphere mechanism (at least for Cr2+ reductions) with attack of reductant at the remote nitrogen atom of the organic ligand is interpreted in terms of the non reducibility of the uncomplexed ligands.
    Notes: Die Kinetik der Reduktionen von μ-3-Cyanobenzoato-di-μ-hydroxo-bis-[triamminkobalt(III)] und dem analogen μ-4-Cyanobenzoato-Komplex durch jeweils [Cr(H2O)6]2+ und [V(H2O)6]2+ in saurer wäßriger Lösung bei 25°C wurde untersucht. Die Reduktion des ersten CoIII ist geschwindigkeitsbestimmend in allen Fällen. Allen Reaktionen wird ein outer-sphere Mechanismus zugeordnet.
