BS EN ISO 8987:1996 is a standard that relates to plastics, specifically phenolic resins. The standard outlines a method for determining the reactivity of phenolic resins using a B-transformation test plate. Phenolic resins are synthetic polymers derived from phenol and formaldehyde, and they are commonly used as binders in various applications, including in the manufacturing of composites and molded products.
Here are the key aspects covered by this standard:
Objective: The primary objective of BS EN ISO 8987:1996 is to provide a standardized method for evaluating the reactivity of phenolic resins using a B-transformation test plate.
The standard defines the scope of its application, specifying the types of phenolic resins to which it applies and providing definitions of relevant terms.
Sample Preparation: It outlines the procedures for preparing samples of phenolic resins for analysis.
Test Plate: The standard describes the B-transformation test plate, which is used as a reference for evaluating the reactivity of the phenolic resins.
Reactivity Assessment: It provides guidelines for assessing the reactivity of the phenolic resins by comparing their behavior to the B-transformation test plate under specified conditions.
Reporting: The standard may include instructions on how to report the results of the reactivity assessment, including any relevant technical details.
