11、ad of RF tagged unit case loads.The test is conducted with the unitized load being stretchwrapped by an automated rotary stretch wrapping machinewhile the unitized load is subjected to a stationary RF field,provided by surrounding RF antennae.5.Significance and Use5.1 This test method is intended to
12、 be used as a means toverify the readability of RFID tagged unitized loads.5.2 This test method simulates an RF read point at stage ofunitizing a load using a stretch wrapper.Reading RF tags on astretch wrapper is beneficial because the dynamic rotarymotion of the unitized load within the stationary
