3、ering.1.2 This practice is intended to be used by resilient,adhe-sive and underlayment manufacturers to measure the impact ofa dynamic rolling load over a specific product or a combinationof products.1.3 This practice may be used to evaluate the performanceof joints(sealed or welded)in the resilient
4、 floor covering.1.4 This practice may be used to aid in the diagnosis of aspecific assembly performance and provide comparative evalu-ation.1.5 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provide

7、ccordancewith Terminology F141.4.Significance and Use4.1 The effect of dynamic rolling load over resilient floorcovering system is important since the resistance reflects theability of a resilient floor covering system to properly performunder specific use or condition.4.2 Excessive rolling load ove
8、r an installed resilient floorcovering may cause floor covering system failures such asbond failure,delamination,and finish or coating deteriorations.4.3 The effect of dynamic rolling load shall be measured byqualitative evaluation comparing the tested assembly with astandard assembly.5.Apparatus5.1
9、 Rolling load simulator comparable or similar to theapparatus as described in Annex A1.6.Procedure6.1 Test Assembly:6.1.1 The test assembly shall have a minimum size of 12 in.(30.5 cm)by 24 in.(61.0 cm).6.1.2 The base substrate shall be rigid such as a concreteslab 4 in.(10 cm),a cementitious board
10、or a34in.(1.9 cm)plywood,panel type underlayments,(Practice F1482 providesadditional information),or others.Adhere the flooring testspecimen to the base substrate according to the manufacturersinstallation instructions.6.2 Testing:6.2.1 The test shall run at a temperature of 73 6 5F(2363C)and at 50
11、6 10%relative humidity unless otherwisespecified.6.2.2 Install the wheel to be tested.6.2.3 After proper conditioning,the test assembly should beinstalled and fixed with clamps on the table.The assemblymust not move.6.2.4 Select the wheel path and the number of cycles.Usually a series of 500 cycles
12、is used.6.2.5 Place the required amount of auxiliary weights.Astarting weight of 100 lb(45.4 kg)is generally used to beginthe test.6.2.6 Turn ON the rolling load simulator.1This practice is under the jurisdiction of ASTM Committee F06 on ResilientFloor Coverings and is the direct responsibility of S
