FIELD: medicine, rescue facilities.
SUBSTANCE: method relates to evaluation of protective properties of materials of facial parts of gas masks with respect to β,β'-dichlorethylsulfide by application of its simulator - butyl-β-chlorethylsulfide. Method includes application on one side of material of gas mask facial part of simulator - butyl-β-chlorethylsulfide drops with further analytic determination of the moment of accumulation in sample of limiting amount of simulator. Butyl-β-chlorethylsulfide in tested sample is caught by sorption substrate Quantitative determination of simulator is carried out with application of photocolorimetric method of analysis Limit of sensitivity of detecting butyl-β-chlorethylsulfide constitutes 1·10-3 mg/ml with inaccuracy not exceeding 15%.
EFFECT: technical result lies in possibility to carry out evaluation of protective properties of not only rubberised fabric, but also materials of facial parts of gas masks (rubbers) of various thickness, with increase of evaluation method safety
