GB/T 4852-2002 《Test method for tack of pressure sensitive adhesive tapes by rolling ball》 Related products

The GB/T 4852-2002 "Pressure sensitive adhesive tape initial tack test method (rolling ball method) " standard adopts Part 12 of JIS Z 0237:1991, namely "Inclined ball initial tack test" and Part 4 of the reference part, namely "Rolling ball initial tack test". The main technical difference between this standard and JIS Z 0237:1991 is the type of steel ball used in the test. The steel ball specified in this standard is less than two sizes of steel balls, because these sizes are not common in the Chinese rolling bearing steel ball series. The revised standard adds Method B: Skewed Rolling Ball Method and changes the name from "Pressure sensitive adhesive adhesive initial tack test method (inclined rolling ball method) " to "Pressure sensitive adhesive adhesive initial tack test method (rolling ball method) ". This standard is suitable for evaluating the initial adhesion performance of Pressure sensitive adhesives under specific conditions and is important to ensure product mass and performance Stability.
