Is there no such thing as an exception according to the requirements of the fixed-volume regulation? Only regulated and unregulated? As long as it meets the capacity specifications, it belongs to category one

I also just discovered this issue. According to the definitions in the regulations on pressure vessels, sections 1.4.1, 1.4.2, and 1.4.3 are all classified as Category 1 vessels; in other words, as long as a vessel falls under the provisions of paragraphs 1 and 3 of section 1.3, it is at least a Category 1 vessel. Is that what it means? If that’s not what is meant, then if the volume is less than 25 liters, any pressure level still results in it being classified as Category 1. What kind of understanding is it, exactly?
In accordance with 1.3.5(2) of the Fixed Pressure Vessels Regulations, vessels that fall within the scope of Article 1.4 are uniformly classified as Class I pressure vessels. In other words: first, it is necessary to determine whether the case falls under the jurisdiction of the \"Regulations on Fixed Pressure Vessels\" in accordance with Article 1.3; then, if it meets the requirements of Article 1.4, pressure and other conditions are not taken into account, and such vessels are classified as Category I pressure vessels.
As long as the three conditions of the fixed-volume code are met, it falls under the jurisdiction of that code; the classification is determined based on the design pressure and the type of medium, in accordance with the tables provided at the end of the volume code
In other words, those that meet criterion 1.3 fall under the jurisdiction of the Fixed-Volume Regulations. For classification, two factors need to be considered: the design pressure and the container itself, as well as whether it falls within the range of 1.4. If it falls within that range, then it is classified as Category 1.
Has the original poster made a mistake? Where in the ‘Fixed Code’ is there anything like 1.3.5(2)?
Sorry, it should be A1.3.5(2)......
