This part of ISO XXXXX establishes a system of designation for polystyrene thermoplastic material, which may be used as the basis for specifications.

The types of polystyrene plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties

a)     Vicat softening temperature and

b)    Melt mass-flow rate

and on information about the intended application and/or method of processing, important properties, additives and colorants, fillers and reinforcing materials.

This part of ISO XXXX is applicable to all amorphous polystyrene homopolymers.

It applies to materials ready for normal use, unmodified or modified by colorants, additives, fillers, etc.

This part of ISO XXXX does not apply to expanded polystyrene, styrene copolymers, homopolymers of substituted styrene or those modified with other polymers such as elastomers.

It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO XXXX does not provide engineering data, performance data or data on processing conditions which might be required to specify a material for a particular application and/or method of processing.

If such additional properties are required, they shall be determined in accordance with the test methods specified in Part 2 of this International Standard, if suitable.

In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 4.1).

This document specifies requirements and test methods for the physical properties of powered toothbrushes in order to promote the safety of these products for their intended use.

There are different technologies of power toothbrushes. Common features of those powered toothbrushes for which this document applies:

—    a battery;

—    a motor;

—    a mechanical or magnetic drive system;

—    a moving brush head with tufts.

Power toothbrushes may have different motions of the moving brush head (e.g. oscillating-rotating, side-by-side) and may have different frequencies and velocities for the moving brush head.

The requirements listed in this document shall be fulfilled for all types of power toothbrushes if applicable. However, some requirements may not be applicable for all types, e.g. brush head retention can only be applied if the brush has a head portion that might get detached from the brush tube.

Excluded are other types of powered oral hygiene devices (such as powered interdental brushes) and manual toothbrushes.
