A manual orreport in this series consists ofan orderlypresentation ofapplications of thesefacts.ltcontainsinformationuseful to the average engi-neerinhiseverydaywork ratherthan thefindings thatmaybeuseful onlyoccasionally or rarely.It is not in any sense a“standard ”however;nor is it so
Furthermore material in this series in distinction from a paper (whichexpresses onlyoneperson'sobservationsor opinions) is the workofa -mittee or group selected toassemble and express information ona specificmore of the Technical Divisions and Councils and the product evolved hasbeensubjected toreviewbytheExecutiveCommitteeofthatDivision.oroftenbroughtbeforethemembersof theTechnicalDivisionsandCouncilsforeachwork shows thenamesof themittees bywhichitwascqmpiled ard indicates clearly the several processes through which it has passedinreview inorderthatitsmerit maybedefinitelyunderstood.

Boiler andPressureVessel Code and the SteelPlateFabricator'sManual.
The ASME Boiler and Pressure Vessel Code (ASME Code) has been in existence since 1914 and originally was based on an allowable stress of one-fifth the tensile strength of the steel.Anthe stressbasis was changed to one-fourth of the tensile strength of the steel.Thehigh-stress altemative rules based on one-third of the tensile strength of the steel came outin the1960s althoughthe theory and stressbasishadbeeninuseforsome timebefore that.FabricationSectionVill of theASME Code are accepted worldwide and havebeen applied tomany types of based on theserules hasresulted inhigh-quality structures. Therules for both divisions ofVill Division 1 and 2 have been used extensively in preparing this manual.
Thedevelopment of theSteelPlateFabricator'sManua/wasbasedprimarilyonthe40-plusofReclamation.Themanualprovides more specificpenstockdesigninformation than the ASMECodebutrefers to the latterforfabrication and welding.
