2、year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.

3、Department of Defense.1NOTEA key was editorially added to Fig. 1 in January 2018.1. Scope1.1 This specification covers the requirements for direct andindirect reading sight liquid level indicators for general appli-cations. General applications for indirect reading sight glassesare water and fuel se

4、rvice at working pressures 2.07 MPa (300lb/in.2) and below, temperatures of 149C (300F) and below.General applications for direct reading sight glasses are appli-cations in which the temperature does not exceed 66C(150F).1.2 Direct reading sight glass indicators may consist of glassor plastic tubes

5、with fittings including shutoff valves. Glasstubes may be used for low shock direct reading sight glassindicators in which the fluid is not compatible with plastic.1.3 Indirect reading indicators may consist of a sealedchamber with a magnetic float or flag indicator.1.4 Special requirements for nava

21、he specifications andstandards as applicable.6.3 Gaskets and O-RingsGaskets and O-rings shall befabricated of materials suitable to the operating pressure,temperature, and process medium for each application.7. Physical Properties7.1 ConnectionsSight indicators are usually installed us-ing standard

22、pipe fittings or flanges. Pipe fittings and materialshould match that of the existing pipe for each installation.Type and size of fittings shall be specified in the acquisitionrequirements. Welding or brazing shall be performed in accor-dance with industry standards.7.2 Flanged ConnectionsWhere sigh
