4.1 Devices shall not be capable of causing
chemical contamination of meat or edible
offal, damage to the hide, or be capable of
adversely affecting the health and
well-being of cattle following attachment.
The likelihood of devices becoming physical
contaminants in meat or edible offal must be
remote.
4.2 There should be no apparent physical
deterioration (other than colour) in devices
due to ultraviolet radiation, rain, heat and
cold or other environmental influences
within 3 years of installation on cattle in
Australian conditions.
4.3 The transponder within Breeder and
Post-breeder devices shall be reliably
machine readable for a minimum of 7 years
following the installation of devices in
typical Australian field conditions.
4.4 The physical loss of devices from cattle
on typical Australian beef, dairy and
feedlot properties shall not exceed 3%
within 3 years under normal field
conditions.
4.5 Once an animal is in a head bail,
installation of devices shall take no more
than 30 seconds per animal, pose no undue
risk to the operator and cause minimal
discomfort or danger to the animal. The
installation of devices shall fail due to
device breakage or applicator equipment
failure on no more than 2% of installation
attempts.
4.6 Printing on devices shall be easy to
read at a distance of 0.75 metres. Devices
installed on live adult cattle restrained in
a race or crush shall be visually readable
without undue risk to persons involved in
the reading. Devices shall remain visually
readable for 7 years.
4.7 To minimise the opportunity for
unauthorised removal and reuse, devices
shall be tamper resistant in that for ear
tags it must not be possible to remove an
installed device from cattle and reuse it
without damaging the component of the device
containing the transponder. Devices or the
transponders they contain, however, may be
recyclable.
4.8 It must be possible to install Breeder
and Post-breeder devices on cattle from 6
months of age.
4.9 To maximise tag retention Breeder and
Post breeder device components shall not be
interchanged with approved Transaction Tags
or management ear tags
