Abstract
The high performance increasingly required of modern plant leaves smaller margins for error in design and makes the plant more sensitive to unforeseen phenomena. This shows itself in many industries in a high incidence of teething trouble, bringing heavy financial loss to the purchaser and discouraging further innovation. The remedy is more thorough design and development and, wherever possible, the full-scale on-load prototype testing of complete plant items before delivery, so as to expose and eliminate teething troubles and to provide the designer with an accurate record of the behaviour of the plant. It is in the purchaser's interest to make such testing a requirement of the contract. Adequate test facilities are at present lacking and can seldom be provided by individual manufacturers. A permanent fully equipped test facility has great advantages compared with ad hoc testing arrangements in various locations, and the paper proposes the establishment of publicly operated testing and development stations to serve various industries. The equipment and procedure of such a station to serve the steam power and allied industries are examined.
