Ships and marine technology. Ball valves for use in low temperature applications. Design and testing requirementsWhat is this standard about? This document specifies requirements for design, manufacture and test methods of cryogenic ball valves in order to have an excellent quality leakage stability in a very low temperature service (196 C to 80 C).

Purpose and planning

design attributes

you can be ensured of rules and graphical symbols for the representations of splines and serrations

A minimum airburst volume has been introduced for mid-body width condoms

This test setup has been used to characterize the stress of advanced technical alumina ceramics for orthopaedic implants

cyclic (12 h + 12 h cycle)

Depending on the memory size of the transponder more data can be stored

BS EN 61000-4-17 establishes a common and reproducible basis for testing

ladle heating

sampling of discharges such as treated sewage effluents and trade discharges and sampling of water used for non-potable purposes can also have a significant impact on public health

Provisions for maintainability

The main forces leading to failure of turbomolecular pumps are torques around the rotational axis
