In "GB 13042-2008 Iron aerosol cans for packaging containers" and "GB/T 25164-2010 25.4mm aluminum aerosol cans for packaging containers", it is clearly stated that this standard is applicable to 25.4mm diameters. . Aerosol cans with a volume not greater than 1000ml. Then why define that the jar used for aerosol does not exceed 1000ml, why not exceed 1000ml?

According to item 1950 of "GB 28644.2-2012 Dangerous Goods Limited Quantities and Packaging Requirements", aerosols, AEROSOLS, are classified as Class II, with limited quantities of 120ml or 1La. Observe carefully, I also brought a number a. Number a is "aerosols containing toxic substances, the limited number is 120ml, all other aerosols, the limited number is 1L".

Why should a tolerance be established?

There are frequent accidents in the transportation of hazardous chemicals, causing great losses to the people and society. Therefore, we have formulated similar standards. First, in order to protect the safety of property and life, and protect the environment from harm, and second, to facilitate the transportation and the transportation of small items. On the other hand, under the same conditions, the larger the diameter, the more dangerous items such as gas can be contained, the greater the hazard of an explosion, and the more serious the consequences, that is, the more dangerous. On the other hand, the size of the palm of the human body is limited. Usually when we use aerosols, we need to hold the can with our fingers and hold the nozzle to operate. If the container is too large, it is not easy to operate.
