AL-1827-8092 Rev C.pdf

This is a technical drawing/engineering specification document for an acrylic storage ring cover assembly component. The drawing is designated AL-1827-8092, released by Ernest Orlando Lawrence Berkeley National Laboratory at the University of California, and is classified as an Advanced Light Source (ALS) component for staging and design purposes.

The document specifies detailed manufacturing requirements for a cover assembly with acrylic material (PTC left side mount assembly). Key specifications include dimensions in millimeters with tolerances, surface finish requirements per ASME Y14.36M standard, and finishing specifications such as removal of burrs and break edges per ASME Y14.5. The drawing references applicable standards including ASME Y14.5M-2009 for dimensioning and tolerancing, ASME Y14.38 for abbreviations and acronyms, and ANSI/AWS AS4.4 for welding symbols. Manufacturing notes indicate all dimensions and values are in millimeters, with values in brackets and parentheses representing U.S. customary units. The component design incorporates multiple radius specifications (R3, R5, R6) and includes detailed dimensional callouts for precise fabrication. The drawing was authored by L. Dennis, checked by DT-p011_dgx0kdsx, and released on April 2, 2026 at 8:30:53 AM PDT, with subsequent release on April 2, 2026 at 8:52:05 AM PDT.
