Flexible cellular polymeric materials - Determination of fatigue by constant-load pounding
 N SN EN ISO 3385

Annotation

This International Standard specifies a method for the determination of loss in thickness and loss in hardness of flexible cellular materials intended for use in load-bearing applications such as upholstery.

It provides a means of assessing the service performance of flexible cellular materials based on rubber latex or polyurethane used in load-bearing upholstery.

This method is applicable both to standard size test pieces cut from slabstock material and to shaped components. The measured loss in thickness and loss in hardness are related to, but are not necessarily the same as, the losses likely to occur in service.

This international standard is not intended to function as a detailed engineering design specification for fatigue apparatus.

Гибкие клеточные полимерные материалы - Определение усталости обстрелом постоянного груза

Этот Международный стандарт определяет метод для определения потери в толщине и потери в твердости гибких клеточных материалов, предназначенных для использования в имеющих груз заявлениях, таких как обивка.
