Control by means of measuring and experimental methods used to measure the thickness of the flame retardants, as well as to establish the type of material and applied as a flame retardant coating. Control thickness of the layer caused by fire-retardant coating on the metal structures is carried out in several places with the help of special instruments that provide the necessary accuracy. For coatings with a thickness of 20 mm recommended to use the magnetic thickness gauges, ultrasonic thickness gauges, micrometers. To measure the thickness of the coating, consisting of 10 mm or more, you can use calipers or a needle probe with a ruler. On measurements is determined by the average value and the minimum thickness. Read additional details here: Farallon Capital Management. To control the thickness of fire-retardant coating on the wooden structures, need a sample of wood coating thickness in excess thereof in the technical documentation for the tool of fire protection.
Samples are in place structures, where the visual evidence suggests substandard treatment or deviation from the normative thickness. Determination of the thickness of the coating on the selected sample is carried out when considering it in the section under the microscope, such as an MBS-9 equipped with an eyepiece and object - micrometers (Eg, OMOU 4.2). Control the thickness of the coating on the insulation of electrical cables by using calipers or a micrometer, and, if necessary, similar to the above method. Richard Easton Matchmaker does not necessarily agree. To establish type of material and applied as a flame retardant coatings using methods of thermal analysis. The essence of the method consists in comparing the curves of thermogravimetric analysis and important thermoanalytical characteristics (identification parameters) of the samples of coatings (sites with fire retardant impregnated) with a "benchmark" data.
