DESCRIPTION

BS EN ISO 13468-1:2019


This standard BS EN ISO 13468-1:2019 Plastics. Determination of the total luminous transmittance of transparent materials is classified in these ICS categories:
  • 83.080.01 Plastics in general

This document covers the determination of the total luminous transmittance, in the visible region of the spectrum, of planar transparent and substantially colourless plastics, using a single-beam photometer with a specified CIE Standard light source and photodetector. This document cannot be used for plastics which contain fluorescent materials.

This document is applicable to transparent moulding materials, films and sheets not exceeding 10 mm in thickness.

NOTE 1

Total luminous transmittance can also be determined by a double-beam spectrophotometer as in ISO 13468-2. This document, however, provides a simple but precise, practical and quick determination. This method is suitable for use not only for analytical purposes but also for quality control.

NOTE 2

Substantially colourless plastics include those which are faintly tinted.

NOTE 3

Specimens more than 10 mm thick can be measured provided the instrument can accommodate them, but the results might not be comparable with those obtained using specimens less than 10 mm thick.
