Classifications for pressure vessels ( Ⅰ,Ⅱ and Ⅲ),toxicity and inflammability of substances
 
1. Classification the categoryⅠ,Ⅱ and Ⅲ pressure vessels:
1.1 Vessels under one of the following conditions are defined as the category Ⅲ pressure vessels:
1.1.1 High pressure vessels;
1.1.2 Medium pressure vessels(for containing extreme or highly toxic substance only);
1.1.3 Medium pressure storage vessels(for containing inflammable or moderate toxic substance with the product of Pressure and Volume greater than or equal to 10 MPa·m3 only);
1.1.4 Medium pressure reaction vessels (for containing inflammable or moderate toxic substance with the product of Pressure and Volume greater than or equal to 0.5MPa·m3 only);
1.1.5 Low pressure vessels(for containing extreme or highly toxic substance with the product of Pressure and Volume greater than or equal to 0.2MPa·m3 only);
1.1.6 High pressure or medium pressure tubular waste-heat boilers;
1.1.7 Medium pressure glass-lined vessels;
1.1.8 Pressure vessels made of the materials with standard specified tensile strength lower limit greater than or equal to 540MPa;
1.1.9 Transportable pressure vessels including railway tank(containing substance of liquefied gas or cryogenic liquid),tank truck(trailers containing substance of liquefied gas, cryogenic liquid or permanent gas)and tank container(containing substance of liquefied gas or cryogenic liquid) etc.;
1.1.10 Spherical tanks(volume greater than or equal to 50 m3)
1.1.11 Cryogenic storage vessels with insulation (volume greater than 5 m3)
1.2 Vessels under one of the following conditions are defined as the category Ⅱpressure vessels(excepting those specified in item 1.1 );
1.2.1 Medium pressure vessels;
1.2.2 Low pressure vessels (for containing extreme or highly toxic substance only);
1.2.3 Low pressure reaction vessels and low pressure storage vessels(for containing inflammable or moderate toxic substance only);
1.2.4 Low pressure tubular waste-heat boilers;
1.2.5 Low pressure glass-lined vessels;
1.3 Low pressure vessels are defined as the category Ⅰ pressure vessels(excepting those specified in item 1.1 and 1.2 ).
2. Classification the toxicity and inflammability 
2.1 The classification for toxicity and inflammability of chemical substances contained in pressure vessels shall refer to the provisions ofHG20660 Classification for Toxicity and Explosiveness of Chemical Substances in Pressure Vessels. When no corresponding standard or code may be referred to,the toxicity should be classified by the following rules:
2.1.1 Extreme toxic(GradeⅠ): Maximum permissible concentration <0.1mg/m3;
2.1.2 Highly toxic(GradeⅡ): Maximum permissible concentration 0.1~<1.0 mg/m3; 
2.1.3 Moderate toxic(Grade Ⅲ) Maximum permissible concentration1.0~<10 mg/m3; 
2.1.4 Light toxic(Grade Ⅳ) Maximum permissible concentration ≥10 mg/m3                            
2.2 For mixed substance contained in a pressure vessel, the classification for toxicity and inflammability shall be based on the composition of mixed substance with respect to the above rules ;and shall be provided with a classification basis report by the process design department of the designer, or the production and technology department of the user. When no such basis report is provided ,the grade of the highest toxicity substance or the utmost explosiveness of the substance shall be determined as the grade of mixed substance.
