This document specifies possible manufacturing tolerances for plastic moulded parts.<\/p>\n
This document specifies all integral features with general tolerances with surface profile tolerance within a specified datum system. It allows for additional specifications in case of functional needs and requirements using the ISO-GPS-tools for dimensional and geometrical tolerating.<\/p>\n
This document addresses injection moulding, injection compression moulding, transfer moulding, compression moulding and rotational moulding of non-porous moulded parts made from thermoplastics, thermoplastic elastomers and thermosets of thermoplastics. This document is applicable to other plastic processes if agreed to by the contractual parties.<\/p>\n
Moulded part surface imperfections such as sink marks, undesired flow structures and roughness, as well as joint lines are not addressed in this document.<\/p>\n
This document is not intended to supplant, replace or in any way interfere with requirements for tolerances found in product standards.<\/p>\n
