5.2 Средняя толщина стенки еm
В таблицах 6 и 7 приведены два квалитета допусков для минимальной толщины стенки еy,min до 50 мм. Квалитет допусков устанавливают в стандартах на продукцию. Значения допусков в таблицах 6 и 7 вычислены из следующих соотношений, где все значения выражены в миллиметрах; эти соотношения основаны на практическом опыте экструзии труб из термопластов толщиной стенки до 50 мм.
