Usage:
ISO 5628 Stiffness of the paper testing machine uses advanced electronic monitoring and control technology and computer technology, the performance has improved significantly, with low power consumption, speed, clarity of liquid crystal display, simple operation, fast, high-tech mechanical and electronic integration. Stiffness is a measure of bending resistance strength of paper and cardboard targets, this instrument is used to determine the stiffness of paper and board special equipment. It suitable for the quantitative determination of the paper and board stiffness which thickness less than 1mm particularly.
Principle:
ISO 5628 Stiffness of the paper testing machine is designed based on the principle of static bending, ie bending a vertical grip the free end of the sample, when the sample to a certain resistance when bending is the angle of bending stiffness, in units of mN; or the length of the product and test resistance , in units of mN • m. ISO 5628 Stiffness of the paper testing machine is in full compliance with ISO 5628 "Paper and board - Determination of static bending of general principles" requirement.
Design criteria
ISO 5628 Stiffness of the paper testing machine reference standard: ISO 5628, GBT 2679.3.
