Test conditions for numerically controlled turning machines and turning centres - Evaluation of thermal distortions Ingestion-build-132972 BS 3900-0 has been fully1 Scope This part of ISO 13041 specifies, with reference to ISO 230 3, the tests which apply for the evaluation of thermal distortions of the machine structure and positioning system, up to 2 000 mm in length, of numerically controlled (NC) turning machines and turning centres. Hence, this part of ISO 13041 defines three tests which are the environmental temperature variation error test, the test for thermal distortion caused by a rotating spindle,
