May I ask about the maximum filling capacity for tank trucks (hazardous **)?

Based on our actual situation, 32% alkali, concentrated sulfuric acid, and dilute sulfuric acid are generally all packaged in quantities of 30 tons
The capacity of the tank trucks used for liquid chlorine by Wuhan Zhongzheng should not exceed 25 tons; the volume can be calculated based on the density of liquid chlorine. Tank trucks used for alkaline solutions are generally not allowed to carry more than 38 tons, although in practice their capacity is often over 80 tons.

What is the maximum filling capacity (in terms of volume percentage) for liquid **chemical tank trucks? ------Let me guess what those two words with asterisks are It refers to danger, right? Now, using the term \"danger\" is not appropriate either; it’s too much. The pinyin for \"danger\" is wei*an. There are many types of liquid **chemicals, and it depends on the properties of the liquid: whether it is toxic or explosive, whether it vaporizes easily or not, whether it is corrosive or has other properties. There are classifications for hazardous substances. Regarding what the original poster mentioned, there are definitely regulations regarding mobile pressure vessels (tank trucks) used to transport hazardous liquids; I searched for them online. Article 36 of the Regulations on Safety Technical Inspection of Pressure Vessels: The designed storage capacity of pressure vessels used for storing liquefied gases shall comply with the following provisions: 1. For fixed pressure vessels containing liquefied gases (including liquefied petroleum gas), the designed storage capacity shall be calculated using the following formula: W = фVρt, where W represents the storage capacity, and t… ； f – filling coefficient; generally taken as 0.9. For containers whose volume has been determined experimentally, a value greater than 0.9 may be used, but it must not exceed 0.95 ； V —— Volume of the pressure vessel, m3 ； ρt – Density of the saturated liquid at the design temperature, in t/m3. 2. The maximum allowable filling volume of a mobile pressure vessel filled with liquefied gas shall be calculated using the following formula: W = фvV, where W is the maximum allowable filling volume of the vessel, in t ； fv – the amount of material per unit volume, determined based on 8% of the tank volume being occupied by gas at 50°C and the density of the material at that temperature, in t/m3. V – the actual volume of the tank, in m3
Are there any regulations regarding the filling capacity of pressure vessels at atmospheric pressure?
My understanding is that Article 36 of the Regulations on Safety Technical Inspection of Pressure Vessels applies equally to atmospheric-pressure tank trucks, including the filling of such tank trucks.
I can give you a formula for the fill capacity
