Qeexitaanka ASTM A242 waa qeexitaanka caadiga ah ee birta qaabdhismeed hooseeya ee xoogga sarreeya ee xubnaha qaabdhismeedka halkaasoo kaydinta miisaanka iyo iska caabinta daxalka jawiga ay muhiim u yihiin. Shuruudaha hantida makaanikada waxaa lagu qeexay nooca badeecada (taarikada iyo baararka, iyo Qaababka qaabdhismeedka) iyo dhumuc ahaan

ASTM A242 birta waxay leedahay iska caabin daxalka atmospheric
Saxanka birta ee hoos yimaada heerka ASTM A242 waxa kale oo loo yaqaan saxanka birta cimilada, oo loo tixraacayo birta la dilay ama si buuxda loo dilay. Waxay leedahay iska caabin daxalka atmospheric wanaagsan si birta waxaa loo isticmaali karaa meelo badan oo shaqo.

ASTM A242 birta cimilada ayaa aad uga wanaagsan tan kaarboon qaab dhismeedka birta oo leh ama aan lahayn naxaas lagu daray.

Guryaha makaanikada A242:
