The manufacturer shall ensure that all indicators of the products shipped out of the factory meet the standard requirements, and each batch of Miehailing Aerosol Type C shipped out of the factory shall be accompanied by a quality certificate. 4.2 The atomization rate is a type inspection item and shall be inspected once a week. 4.3 The quantity of each batch of Miehailing Aerosol Type C products shall not exceed the maximum capacity of the preparation label. 4.4 Samples shall be taken from 0.2% of the packaging of each batch of products, and small batches shall not be less than three boxes; one can shall be randomly selected from each packaging box, and approximately equal inspection samples shall be taken from each can, with a total amount of not less than 0.25L, for the detection of active ingredients and acidity; other items shall be tested by sampling from the original packaging. 4.5 The user unit has the right to verify whether the received products meet the requirements of this standard in accordance with the provisions of this standard. 4.6 In the inspection results, if some indicators do not meet the standards, samples shall be taken from twice the amount of packaging for re-verification. If the result of the re-verification shows that only one indicator does not meet the requirements, the entire batch of products shall be unqualified. 4.7 When the supply and demand parties have disputes over product quality and cannot resolve them through negotiation, the legal inspection agency shall conduct arbitration analysis according to the inspection methods specified in this standard.
5 Marking, packaging, transportation and storage
5.1 Miehailing Aerosol Type C is packaged in tinplate cans with a deformation pressure greater than or equal to 1.2MPa, a burst pressure greater than or equal to 1.4MPa, and a plastic cover. The net capacity of each can is 600mL. Every 24 cans of products are tightly arranged in a cardboard box, and the net weight of each box does not exceed 15kg; other forms of packaging can also be used according to user requirements. 5.2 Each box of packaging should be printed with the manufacturer's name, address, product name, specifications, production date, standard number, and drug, fire prevention and other signs, and each box is accompanied by a quality certificate.
5.3 Each can is printed with the product name, manufacturer name, factory address, net capacity, prevention and treatment targets, usage, precautions, registration certificate number, production license number, active ingredients, production date, and signs such as drugs and fire prevention. 5.4 Storage and transportation shall be carried out in accordance with the "Dangerous Goods Transportation Rules" of the Ministry of Transport; this product shall not be stored or transported together with food, and transportation, loading and unloading shall be handled with care, violent impact is strictly prohibited, and it shall not be inverted. 5.5 The product should be stored in a cool, ventilated and dry place, avoid being close to high temperatures, and exposure to the sun is strictly prohibited. 5.6 The shelf life of the product is two years under the above storage and transportation conditions. 6

HG/T2218.3-91bzxz.net
Take two cans of samples, shake them several times, place them in a fume hood, remove the outer cover, gently twist off the safety cover and pull out the nozzle, align the inlet of the pressure gauge with the valve core of the Miehailing, press hard, and read the indicated pressure of the two cans. Product pressure X. Calculate according to formula (8):
Xg=p+(55-t)X 0.012
Where: p——average value of indicated pressure, MPa; 55——temperature specified in the standard, ℃; t——temperature when measuring pressure, ℃;
0.012——pressure correction coefficient, MPa/℃. 4 Inspection rules
