This part of the standard specifies the method for determining the tensile strength of the manufacturing connection parts of corrugated and compact fiberboard boxes for transport Encasement. The scope of application includes gluing, binding, etc. Manufacturing connection bonding methods. The standard refers to a series of normative documents, including paper and Cardboard specimen taking and test standards, standard atmospheres for paper, Cardboard and pulp specimen handling and testing. The terminology and definitions section gives the definition of tensile strength. The principle is to cut the specimen, place it on a tensile strength tester, stretch it at constant speed until it is damaged, and determine its tensile strength. The instrument includes a tensile strength tester and a cutting device.
