The powerful radio waves can ignite explosive gases. Therefore. it is necessary to reasonably set the radio wave explosion-proof safety power and energy threshold emitted by the radio transmitter to limit the radio wave power and energy emitted by the radio transmitter. The radio wave explosion-proof safety power and energy thresholds specified in European Standard CLC/TR 50427:2004 A... https://lecoureures.shop/product-category/course-a-pied-accessoires-hydratation-bouteille/
