2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. GB/T 21782.9-2010 powder coatings - Part 9. Sampling Principle 3 Epoxy powder coating material is pressed into a cylindrical mold standard size, made of molded specimen. At a predetermined temperature, the sample is placed in the horizontal holder Or on a predetermined angle of inclination of the glass holder to maintain a predetermined time after the sample is taken out carrying glass, natural air to room temperature measurements. tilt Liquidity is represented by the total length of sample after melt flow. The level of liquidity than the melting sample for the sample before and after the diameter of the variable diameter of the initial one hundred Fraction representation. After the hot-plate horizontal flow test method is a hot plate heated to a predetermined temperature and constant, the molded sample was placed on a hot plate, the count immediately When, after holding a predetermined time, vernier caliper diameter of the sample, with the sample before and after the melting of the sample than the diameter of the variable diameter of the initial one hundred Fraction representation.
