When the lid moves to one side, the distance from the lid to mouth shall not exceed 3 mm. The tip of spout of pots shall not be 3 mm lower than the pot mouth. 5.9.5 The marking on the bottom shall be correct and clear; it shall not be conspicuously deflective or eccentric. 5.9.6 The appearance defects of products of all grades shall be as specified in Table 3 and shall conform to the following requirements. a) not more than 2 defects for each super-grade product; b) not more than 4 defects for each first-grade product; 6.7.1.1 One microwave oven with a microwave output power not less than 600 W. 6.7.1.2 One refrigerator which is capable of controlling the temperature difference within the working area within ± 3°C. 6.7.2 Determination Immerse samples in water at temperature (20 ± 3)°C for 1 h; take out and use cloth to wipe them dry. Place a sponge soaked in water with a size of one half of the bottom place of samples [having identical shape to the bottom of samples and thickness not less than 15 mm] on samples; immediately place into a cabinet freezer at -8°C; preserve temperature for 16 h after the temperature is achieved; place samples, within 45 s after taking out, in the middle of microwave oven turntable for microwave heating [one container containing (125 ± 2.5) mL of water is placed at two corners of the microwave oven, which shall not touch the turntable], with heating energy 72 000 J and heating-up duration obtained by dividing energy by power, accurate to second; place into a cabinet freezer at -8°C within 45 s after heating; preserve temperature for 16 h after the temperature is achieved; take out samples to cool down to room temperature and check whether samples crack.
