DIN Standards Committee Plastics

Abstract

This standard specifies tolerances and acceptance criteria for extruded profiles made of thermoplastic materials and is intended to simplify drawings and other documentation (e.g. terms of delivery). This standard does not apply to extruded profiles for which tolerances are specified in other standards (e.g. dimensional standards, technical delivery conditions, RAL quality and testing specifications). Surface imperfections in profiles, such as sink marks, undesirable flow patterns and roughness, as well as weld lines, are not covered in this document and have to be agreed between the parties involved, e.g. the client and the contractor. This standard applies exclusively to the thermoplastic component of the profile. In the case of profiles containing other materials (e.g. metals, glass fibre, elastomers), the standard does not apply to those components.
