Standard Test Methods for Softening Point of Hydrocarbon Resins and Rosin Based Resins by Automated Ring-and-Ball Apparatus
 N D6493

Annotation

These test methods are intended for determining the softening point of hydrocarbon resins, rosin based resins and similar materials by means of an automated ring-and-ball apparatus. Portions are similar in technical content to the automated-apparatus versions of Test Methods D36, E28, and ISO 4625.

The ring-and-ball softening point of a hydrocarbon resin and rosin based resins may also be determined with lower precision using the manual ring-and-ball softening point procedure in Test Methods E28.

The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

This standard method does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Методы стандартной пробы для точки размягчения углеводородных смол и канифоли основанные смолы автоматизированным прибором "кольцо и шар"

Эти методы тестирования предназначаются для определения смягчающей точки смол углеводорода, канифоль основывала смолы и подобные материалы посредством автоматизированного аппарата кольца-и-шара. Части подобны в техническом содержании версиям автоматизированного аппарата Методов тестирования D36, E28 и ISO 4625.
