ISO 8627:1987 PDF Download

An ISO 8627:1987 standard describes a test procedure and grading system for determining how stiff the tufted area of traditional manual toothbrushes is. The standard also offers definitions and instructions for the testing of the process's machinery.

The classification standard now only has three categories—soft, medium, and hard—instead of the original five. According to this classification scheme, the stiffness of toothbrush-tufted areas can be graded using a more streamlined and consistent method.

Eight definitions of key terminology linked to the testing and categorization processes are also included in the standard. These definitions are essential for guaranteeing accuracy and consistency in toothbrush stiffness measurement and grading.
