According to ASHRAE standard 34, the R-number of a chemical refrigerant is assigned systematically according to its molecular structure and has between two and four digits. If there are carbon -carbon multiple bonds , there are four digits in all: the number of these bonds is the first digit and the number of carbon atoms minus one (C-1) is next.
The list was consolidated and republished in Directive 2001/59/EC, [1] where translations into other EU languages may be found. These risk phrases are used internationally, not just in Europe, and there is an ongoing effort towards complete international harmonization using the Globally Harmonized System of Classification and Labelling of ...
Parts that are not repairable are considered consumable parts. Consumable parts are usually scrapped, or "condemned", when they are found to have failed. Since no attempt at repair is made, for a fixed mean time between failures (MTBF), replacement rates for consumption of consumables are higher than an equivalent item treated as a repairable ...
The car types, which were part of the MTA NYCT GOH program, are the IRT Redbirds (R26, R28, R29, R33, R33S, R36), as well as IND/BMT cars (R30 GE, R32, R38, R40, R40A, R42, R44, and R46). These cars were rebuilt between 1985 and 1993. Some cars in various classes from R10 to R46 were also given lighter overhauls during this period.

Eli Terry was using interchangeable parts using a milling machine as early as 1800. Ward Francillon, a horologist, concluded in a study that Terry had already accomplished interchangeable parts as early as 1800. The study examined several of Terry's clocks produced between 1800–1807. The parts were labelled and interchanged as needed.
A business using a part will often use a different part number than the various manufacturers of that part do. This is especially common for catalog hardware, because the same or similar part design (say, a screw with a certain standard thread, of a certain length) might be made by many corporations (as opposed to unique part designs, made by only one or a few).
The rebodied R20/R30 was introduced in January 1992 and produced until September 1996. For this series, the mechanicals were largely carried over (hence the retention of the R20/R30 chassis codes), but the styling fully refreshed. [29] At this time, the LiteAce van became a derivative of the TownAce line, sharing the latter's body work.
