BS ISO 19594:2017 pdf free.Graphic technology一Test method for the determination of the binding strength for perfect-bound products Page-pull test working upwards.
BS ISO 19594 The binding strength is evaluated by pulling out a single sheet from the book block using a material testing system and a specified test fixture. The test is performed in such a way that the test sheet is clamped on the complete fore edge while the opened book block is fixed at the specimen holder with a specified preload. The test sheet is pulled out upwards by a force acting perpendicular to the binding edge. The maximum force resulting from the pull-out procedure is measured. The binding strength of the specimen is calculated by dividing the maximum force by the spine length of the book block.The material testing system shall be constructed as a twin-column device that shall be able to perform tensile testing and to apply a preload. It contains an upper moveable traverse, where the force transducer is located. The horizontal working space of the material testing system is determined by the maximum spine length of the products tested. A scheme of the material testing system, including the test fixture (see 5.2), is shown in Figure 1.The vertical guide is positioned between the force transducer and the sheet clamping unit. The vertical guide consists of two parts. The connection between the two parts consists of a centered compensator and means of alignment on both sides. During the application of the preload, both parts lock positively and they are therefore rigid. During tensile testing, both parts are unlocked and flexible to allow tilting.The sheet clamping unit is positioned between the vertical guide and the downholder. The sheet clamping unit consists of two bars designed to clamp the test sheet. During testing, the two bars are closed with a gap remaining. For clamping the test sheet, this gap will be closed. The clamping position of the test sheet shall not change during the test (no slippage). BS ISO 19594 pdf downlaod.
