Unit No. 205, Jaksons Crowne Heights, Hotel Crowne Plaza, Sector-10, Rohini, Delhi -110085 .Edge crush test, right test, or flat crush test helps determine this. In the Edge Crush test, force is applied to one side of the box, perpendicular to the ridges, until the box gets crushed. In the Ring Crush test, a ring cut out from the box is used to test the same. While in the flat crush test, excessive force is applied on one side.Here we will discuss brief information about the ring crush test and how you can easily prepare the specimen for conducting this quality test. So, let us get started! Introduction about ring crush test. The ring crush test correlates with the edgewise compression strength of the paperboard. The strength of the liner or fluting is tested in the .The crush performance characteristic of liner-board and corrugating medium is typically expressed as a Ring Crush value or a Short Span Compression (SCT) value. SCT is the proper name for what is commonly referred to as STFI. The crush performance values of linerboard and medium relate to ECT but are meaningful to
TAPPI-T 822 Ring Crush of Paperboard (Rigid Support Method): Ring Crush Test (RCT) for measuring the resistance of paper and paperboard to edgewise compression. A special jig is used during the test to hold the test piece in a ring form. The ring crush test correlates with edgewise compression strength of paperboard. This method is intended for .

RCT: Ring Crush Test 17-11-13 ECT: Edge Crush Test 17-11-49 PAT: Ply Adhesion Test 17 .Ring Crush is one of the two most common compression tests. Scope and Learning Objectives: These self guided testing labs and video modules demonstrate the procedures used to test paper and board. They will also provide some background about the property being tested. The overall learning objective is to increase your understanding of why and .The STFI instrument measures the compression strength of linerboard and corrugating medium, using essentially a zero span or gap. This test is an alternative to ring crush and is intended to relate to the eventual compression strength of combined board made from the components. The test is run according to TAPPI Test Method T526.
RCT -> RING CRUSH TEST. It is the measure of force required to crush a strip of paper (cut in a predefined size) and is tested in the machine by crushing. It is in the shape of a ring.
