(10) pressure vessels for containing water or other nonflammable liquids under pressure, including those containing air, the compression of which serves only as a cushion, when neither of the following limitations is exceeded:

(A) A design pressure of 300 psig; or

(B) a design temperature of 210° Fahrenheit;

(11) pressure vessels that may be classified as pressure containers that are an integral part of components of rotating or reciprocating mechanical devices such as pumps, turbines, generators, engines and hydraulic or pneumatic cylinders, where the primary design considerations and stresses are derived from the functional requirements of the device;

(12) pressure vessels that do not exceed: (A) 15 cubic feet and 250 psi pressure; or (B) 11/2 cubic feet in volume and 600 psi pressure; and
