1.1 Safety Precautions
Pressure Testing Equipment must be selected and used
in accordance with recognized industry codes and safety
practices to avoid the possibility of misuse or misapplica-
tion which could result in personal injury or property dam-
age. Personnel responsible for selection and installation
should also be familiar with the safety recommendations
of ASME B40.1 that apply to elastic pressure elements
and their application in general and specific services.
ASME B40.1 is available from:
ANSI
1430 Broadway
New York, NY 10018
1. Pressure – Select a range so that the maximum ap-
plied pressure will never exceed the upper range limit.
2. Vibration – Excessive vibration could cause a loosen-
ing of components and abnormal wear resulting in loss of
instrument accuracy or failure to provide valid data.
3. Temperature – Operation of the instrument in an en-
vironment where temperatures are in excess of design
ratings may result in loss of accuracy and failure.
4. Process – Pressure boundary materials must be resis-
tant to the process media. Failure to assure compatibility
may result in pressure boundary deterioration or failure.
Instruments operated at high pressure or with potentially
hazardous service, such as oxygen, should be carefully
selected in accordance with recognized industry codes
and the recommendations of ASME B40.1.
