  2. Standard dimension ratio - Wikipedia

    en.wikipedia.org/wiki/Standard_dimension_ratio

    Standard dimension ratio (SDR) is a method of rating a pipe's durability against pressure. The standard dimension ratio describes the correlation between the pipe dimension and the thickness of the pipe wall. [1] Common nominations are SDR11, SDR17, SDR26 and SDR35. Pipes with a lower SDR can withstand higher pressures.

    The SDR was originally defined in the Air Force's MIL-STD-1521. [ 1 ] The SDR is a technical review conducted to evaluate the manner in which a project's system requirements have been allocated to configuration items , manufacturing considerations, next phase planning, production plans, and the engineering process that produced the allocation.

    Using 32 mm (1.26 in) - 0 gauge - track, there is an extensive range of 16 mm to the foot scale [1:19] live-steam and other types of locomotives, rolling stock and accessories. Many of these models are dual gauge, and can be converted to run on 45 mm ( 1.772 in ) track ( gauge 1 ), and radio control is common.

  9. SMA connector - Wikipedia

    en.wikipedia.org/wiki/SMA_connector

    The interface dimensions for SMA connectors are listed in MIL-STD-348. [5] The SMA connector employs a 1 ⁄ 4 inch diameter, 36-thread-per-inch threaded barrel. The male is equipped with a hex nut measuring 5 ⁄ 16 inch (0.3125 inch / 7.9 mm) across opposite flats, thus taking the same wrench as a #6 SAE hex nut.
