Micrwave radiation requires testing to maintain safe levels of radiation and to ensure that the Microwaves are safe to use.
"Exposure to sufficiently high levels of microwaves will cause heating. In the case of human tissue, excessive heating could have serious health effects, such as deep tissue burns and hyperthermia. The purpose of the Australian Standards is to avoid all adverse health effects by limiting exposure levels to levels below those at which heating occurs."
"This Standard applies to ovens designed for domestic applications, even if used in a workplace."
