Specification for unreinforced and reinforced concrete pipes (including jacking pipes) and fittings with flexible joints (complementary to BS EN 1916: 2002) BS 5911 1 specifies requirements and describes test methods for precast concrete pipes and fittings, unreinforced, steel fibre and reinforced, with flexible joints and nominal sizes not exceeding DN 1750 or WN HN 1200 1800,

These requirements reflect the application of human factors engineering principles as they apply to the human-machine interface during normal and abnormal plant conditions

The skid resistance of a pavement is determined by friction measurements and measurements of pavement texture

Arrangement and requirements for circulating fans

It will not be the intent of this British Standard to imply uniformity in the structure of a BCMS but for an organization to design a BCMS to be appropriate to its needs and that meets its stakeholder’s requirements

BS EN 50121-4:2006 supersedes BS EN 50121-4:2000 which has been withdrawn

Minimum facility requirements for drill-pipe manufacturers

j) an ignition temperature of (950 ± 25)°C has been set for the determination of loss on ignition and the ignition of barium sulfate and insoluble residues

It is aimed at:

the purpose in design should be to reach these limits in as many parts of the structure as possible and to adopt a layout such that maximum structural efficiency is attained for a minimum use of steel
