::Microwave testing To compliment our portable appliance testing we offer a microwave oven radiation leakage and power test. This is carried out to British Standard 5175. :: A Hidden Danger Microwaves let unchecked can pose a hidden health and safety issue particularly among pregnant women. This is particularly important because poor maintenance of door seals, and a lack of cleanliness, can result in excessive radiation leakage in both domestic and industrial microwaves. These tests are carried out using the latest measurement instruments to monitor radiation levels around the microwave, particularly at the door seals and interlocks.
