White,Blue Vicat Softening Point Test Apparatus, Automation Grade: Automatic

Vicat Softening Point Test Apparatus is a device used to determine the softening temperature of materials like plastics. It measures the temperature at which a flat-ended needle penetrates the specimen under a specific load. This test helps assess material behavior under heat. Vicat Softening Point Test Apparatus Vicatsoftening point is the temperature at which a flat ended needle of cross sectional area of 1 mm2 loaded with a weight of 1 kg penetrates 1 mm into a polyethylene sample of thickness varying from 3 to 4 mm when tested in a bath of glycerol which is heated at a rate of temperature rise 500C / h from the room temperature Data obtained by this method may be used to compare heat softening qualities of polyethylene The construction of the apparatus shall be such that the dial gauge reading caused by differential thermal expansion over the intended temperature range does not exceed 0.02 mm when the test specimen is replaced by a piece of borosilicate glass or low expansion alloy steel. It is recommended that the apparatus be constructed of low expansion alloy The penetration of the indenting tip into the test specimen is measured by means of a micrometer dial gauge graduated in divisions of 0.01 mm. The thrust of the dial gauge, which contributes to the thrust on the test specimen , shall be known and shall comply with the requirements laid down in 10810. 22.4.1.4
