    Abstract: This invention relates to a method of evaluating monomers having an effect on copolymer characteristics and a system using the same, and particularly to a novel method of evaluating the magnitude of the effect of monomers on copolymer characteristics, which cannot be evaluated using existing methods. The method of evaluating monomers having an effect on copolymer characteristics and the system using the same are innovative because the extent of changes in copolymer characteristics can be predicted at the monomer level by quantitatively evaluating the effect of the monomers on the copolymer characteristics, taking into consideration the kind or linkage type of monomers.

    Abstract: An oil resistance test method for an electronic device is provided. At least one type of resin material is provided on at least a portion of an outer surface of the electronic device. The oil resistance test method includes: setting a test temperature; and immersing the electronic device in a water-soluble cutting oil in an atmosphere of the set test temperature. This cutting oil contains a mineral oil and a surfactant, and exhibits a milky-white appearance when diluted with water. The oil resistance test method further includes: determining, based on an electrical characteristic of the electronic device, whether or not the electronic device has been degraded by the cutting oil; and estimating, based on a total immersion time of the electronic device in the cutting oil until degradation of the electronic device is detected, a life of oil resistance of the electronic device.

    Abstract: A method for non-destructively testing the heating of a determined zone of a part made of a polymer material, comprising: a) taking at least one colorimetric measurement on said determined zone to be tested and obtaining the values ap, bp and Lp of the parameters a, b and L of the CIELAB colorimetric space; b) taking at least one colorimetric measurement on said reference zone of the part and obtaining the values ap/ref, bp/ref and Lp/ref of the parameters a, b and L of the CIELAB colorimetric space; c) calculating the colour difference ΔEp between the colorimetric measurements obtained in steps a) and b); and d) from the value ΔEp, determining the time period during which said zone to be tested of the part has been subjected to a determined heating temperature, by using a reference database.

    Abstract: Methods are described for microwave extraction of a component from a rubber-containing plant by providing a container holding a mixture of a sample of the rubber-containing plant and a solvent, placing the container holding the mixture in a vessel, irradiating the mixture in the vessel to increase the temperature of the mixture to extract the component from the sample of the rubber-containing plant into the solvent, and separating the extracted component from the solvent to quantify the amount of the component in the sample. Methods are also described for quantifying the amount of natural rubber in a sample from a rubber-containing plant and quantifying the amount of resin in a sample from a rubber-containing plant.

    Abstract: A method and a device for evaluating the distribution and orientation of ferromagnetic, electrically conductive fibers in a composite material are disclosed. The principle consists in repeatable evaluation of the density of ferromagnetic, electrically conductive fibers at the measured location, and such evaluation is performed within a guaranteed scatter range of the measured data and at a guaranteed accuracy rate. A device to perform the method comprises a C, U or E-shaped ferromagnetic core (1) with distributed or uniform winding of the electric coil (2), where the ferromagnetic core (1) exhibits dimensions A, B, and C, for which we have C≥3B and B≈A, where A denotes the width of an arm (1.2), B represents the depth of an arm (1.2), and C is the length of the base (1.1). The ferromagnetic core (1) is equipped with at least two electric coils (2) and, to ensure strong electromagnetic coupling on the ferromagnetic core (1), the winding of the electric coil (2) is configured on both arms of the ferromagnetic core (1). The leads of the electric coil (2) winding are, at the winding terminals (3), connected to an external electric circuit (17) including an electric voltage generator (16) with adjustable frequency f and a measuring device (18).
