Domestic radiation testers do not meet the standard.
Radiation leakage from a microwave oven often occurs through the doors and seals and is invisible. These harmful radiation leakages can cause harm to user’s health.
The Australian Standard states “The microwave leakage at any point 50mm or more from the external surface of the appliance shall not exceed 50W/m2 (5mW/cm2).”
AS/NZ 60335.2.25 ( AS/NZ 3350.2.25) – Australian and New Zealand Standard
The Australian Standard relates to 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 hypothermia. 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. The Standard applies to microwave ovens designed for domestic applications, even if used in a workplace.
The standard says “… microwave ovens used in workplace staff rooms are not excluded from the test approvals process and should be marked with an approvals identification signifying compliance with AS/NZS 3350.2.25:1997”
Employers have a ‘Duty of Care’ to ensure their workplace is safe and as such Perth Testing and Tagging recommends and conducts the testing of microwave ovens in the workplace annually as a minimum standard.
