<p>This document specifies requirements for design, dimensions, material, fabrication and production testing of gate, globe, ball/plug and butterfly valve design types used as isolation valves and check valves for low-temperature applications.</p>
<p>This document is applicable to isolation valves for use in low and cryogenic temperature service where the design low-temperature service is -50 °C down to –196 °C.</p>
<p>This document does not apply to valves for cryogenic services, designed in accordance with ISO 21011, used with cryogenic vessels.</p>
<p>Where the requirements of this document vary from those given in the valve product standards, the requirements of this document apply.</p>
<p>This document is applicable to valves with body, bonnet, bonnet extension or cover made of metallic materials.</p>
<p>This document is applicable to:</p>
<p>— valves of nominal sizes DN: 10; 15; 20; 25; 32; 40; 50; 65; 80; 100; 125; 150; 200; 250; 300; 350; 400; 450; 500; 600; 650; 700; 750; 800; 850; 900; 950; 1 000; 1 050; 1 200; 1 350; 1 400; 1 500; 1 600; 1 650; 1 800,</p>
