defines the size and physical characteristics of the
card. It also lists several environmental stresses that the card must be capable of
withstanding without permanent damage to the functionality. These tests are intended
to be performed at the card level and are dependent on the construction of the card
and on the antenna design; most of the requirements cannot be readily translated to
the die level. The operating temperature range of the card is specified in Part 1 as an
ambient temperature range of 0°C to 50°C.
