42、C 300 7 1The neutralization number method allows the determination of both total acid number and strong acid number. The requirements in this standard is for the measurement of total acid number. 2Fire resistance is also usually specified by means of spray ignition test performance but the preferred
43、 test methods are still undergoing conversion to the ISO format (future ISO 15029-2 and ISO 15029-3). Once the ISO methods have been published, this requirement will be included in the standard. However, the fire resistance of the phosphate esters used in this application is well known and can be de

The existing version refers to the calibration of automatic counting equipment according to ISO 4402 but this standard has been replaced by ISO 11
45、171. ISO 4406 is the procedure for codifying number and size of particles in the sample. 4The limits shown for seal compatibility are for reference purposes and should not be taken as the direct basis on which elastomer compatibility is to be determined as it will depend on the purpose and condition
