Zkratky

Zkratky jsou vybrány z projektové, zadávací a jiné stavební dokumentace různého druhu (časopisů, příruček), a to z britských, amerických a kanadských podkladů. Jsou to zkratky, které jsou Anglosasovi v kontextu většinou jasné, avšak našim inženýrům působí někdy obtíže. — Zkratky byly získány vlastní excerpcí; jen některé jsou převzaty z jiných seznamů zkratek uváděných v severoamerické nebo britské literatuře. Poznamenejme, že zkratky nejsou – až na zkratky označující veličiny – nijak standardizovány; proto se vyskytuje týž význam v různých zkratkových variantách.

Zkratky jsou řazeny abecedně. Pokud se v některých zkratkách vyskytuje jiný než alfabetický symbol (', /, &, @, #), nepřihlíží se k němu. Rozlišují se ale případy, kdy se vyskytuje v praxi psaní bez symbolu a s vloženým symbolem, např. AC, A/C.

Způsob psaní zkratek v literatuře není jednotný. Pro jednoduchost jsou v tomto seznamu všechny zkratky psány velkými písmeny a bez teček, i když se někdy vyskytnou v malých písmenech, eventuálně s tečkou např. "on centre" v našem seznamu je ON, ale můžeme se setkat také s variantou o.c. . Malá písmena jsou zachována jen tam, jde-li o zkratku užívanou pro název měrné jednotky, popř. ve výjimečných případech (např. X-ing, STank aj.).

Český význam zkratek není uveden, předpokládá se, že uživatel seznamu má k dispozici vhodný slovník.

Výklad značek je v americkém pravopisu (tj. vapor, nikoliv vapour), pokud nejde o slovo, které je v názvu britské organizace. Označení (UK) znamená, že jde o britský úzus, popř. britské předpisy. Označení (US) analogicky znamená předpisy platné v USA, popř. severoamerický pravopisný úzus. V dokumentaci z Kanady se můžeme setkat se zkratkami americkými i britskými.
