METHOD OF DETERMINATION OF PROTECTIVE PROPERTIES OF PERSONAL PROTECTIVE EQUIPMENT

摘要

FIELD: testing equipment. ^ SUBSTANCE: invention refers to methods of determination of protective properties of personal protective equipment. Method consists in the following: body is hit with normalised energy against unprotected model of object filled with liquid and also body is hit with specified energy against model of object protected by personal protective equipment; pressure in liquid, positive pulse of pressure in liquid and time change of positive pulse of pressure in liquid caused by hit are recorded. According to data obtained, functional relation of ratio of change of pressure positive pulse to time of its development for each hit is calculated and set up, positive extreme values of function F(t) are found, obtained values of positive extreme values are used for comparison. Function F(t) of hit against unprotected model by pendulum impact machine has one positive extremum Fkmax, and upon hit against protected model it has three positive extreme values. Comparison may be performed as per any of these three positive extreme values. ^ EFFECT: invention allows to improve accuracy of determination of parametres used for evaluation of effectiveness of personal protective equipment. ^ 4 cl, 2 dwg
