13 entries starting with numbers, across every field.

  • 0-10VLighting
    An analog dimming method in which a low-voltage DC signal from 0 to 10 volts sets driver output.
  • 1-2-3 blocksMachine Shop
    Hardened, ground steel blocks measuring 1 x 2 x 3 inches, used for setups, squaring and height stacks.
  • 1.5 sigma shiftStatistics
    Six Sigma convention that assumes a process mean wanders by 1.5 standard deviations over the long term.
  • CP criterion met when a structure is polarized at least 100 mV more negative than its native potential.
  • Fastener shorthand for austenitic 300-series stainless, about 18 percent chromium and 8 percent nickel.
  • 20-degree glossPaper Optics
    Specular gloss measured at a steep 20 degrees, used to separate very glossy papers, boards and prints.
  • 45/0 geometryPaper Optics
    Measurement setup with the sample lit at 45 degrees and viewed straight on, or the reverse.
  • 6010Welding
    A deep-digging cellulosic stick rod run on DCEP, the classic choice for open-root pipe passes.
  • 6GWelding
    Pipe test position with the pipe fixed at 45 degrees, covering every welding position in one joint.
  • 7018Welding
    A low-hydrogen stick electrode with 70 ksi minimum tensile strength, the workhorse rod for structural and pressure work.
  • 75-degree glossPaper Optics
    Specular gloss measured at 75 degrees from the normal, the standard angle for coated and most uncoated papers.
  • Steel counts as protected when its potential is -850 mV or more negative against a copper sulfate electrode.
  • 86 relayElectrotechnology
    Lockout relay that latches after a serious trip and holds breakers open until someone resets it by hand. Shop talk
