This International Standard specifies two test meth-ods for determining whether or not a gas is flammable in air and whether a gas is more or less oxidizing than air, respectively, with the aim of eliminating difficulties entailed in the application of ISO 5145.
NOTE 1 For certain special applications, such as special gas mixtures produced to order (in small quantities), it might prove relatively complex to apply the method speci-fied and to perform the special tests necessary to deter-mine the flammability or oxidizing power of the gas mixture.
To avoid these difficulties, a simple method of calculation is recommended to determine rapidly the type of connection to be employed depending upon the characteristics (flammability, oxidizing power, etc.) of the gas mixture and the characteristics of the pure substances making up the mixture.
