Piirhälve

Piirhälve (inglise keeles limit deviaton, permissible deviation) näitab piirmõõtme ja nimimõõtme algebralist vahet. Suurimale piirmõõtmele vastavat piirhälvet nimetatakse ülemiseks hälbeks (upper deviaton) ja vähimale vastavat alumiseks hälbeks (lower deviation).

Piirhälve on alati märgiga väärtus. Positiivne hälve näitab, kui palju võib detaili tegelik mõõde olla nimimõõtmest väiksem.

Piirhälbed kirjutatakse vahetult nimimõõtme järele.

Piirhälvete märkimine joonistele

Õige on järgmine märkimine:

• Ø30_−0,3^+0,2
• Ø30_−0,15
• Ø30^+0,027
• Ø30±0,2

ISO Standard annab ka mooduse, kus hälbed kirjutatakse erandkorras nimimõõtmega samasuuruse kirjaga.
