ASTM F2054

These test methods cover the procedure for determiningthe minimum burst strength of a seal placed around theperimeter of a fexible package as it is internally pressurizedand enclosed within restraining plates.The test methods described herein are funetionallysimilar to Test Methods Fll40 with the exception of the use ofrestraining plates. Test Methods F1140 describes methods ofburst testing that do not include the use of restraining platesand are suitable to determine a packages general ability towithstand pressurization stresses.Under Test Methods Fl140the stresses are not distributed uniformly to all areas of thepackage seal. Under unrestrained conditions the stress on thepackage is highest at the middle of the pouch where it inflatesto the packages maximum diameter; therefore, Test MethodsF1140 may not reliably detect the weakest area of the seal.
