What is BS EN 16472 – Artificial accelerated photoageing for plastics about? 
BS EN 16472 is a European Standard that covers artificial accelerated photoageing for plastics, enabling the maximization of the photoageing process with high UV emission intensity and low IR emission.
BS EN 16472 specifies a method for carrying out artificial accelerated photoageing of test specimens by exposing them to medium pressure filtered mercury vapour lamp as a light source, under controlled temperature conditions.
Who is BS EN 16472 - Artificial accelerated photoageing for plastics for?  
BS EN 16472 on artificial accelerated photoageing for plastics using medium pressure mercury vapour lamps form is relevant to: 
- Manufacturers of plastic products
- Product designers and specifiers
- Quality control and testing personnel 
- Inspection and maintenance personnel
- Regulatory authorities
Why should you use BS EN 16472 - Artificial accelerated photoageing for plastics? 
When a polymeric material is exposed to natural UV radiation and other moderate environmental stresses, the change in most physical properties is attributable to chemical ageing, and the extent of the chemical changes can be related to the duration of the exposure under natural outdoor weathering conditions.
BS EN 16472 provides you guidance on a test method for artificially accelerating the photoageing of plastics with medium pressure filtered mercury vapour lamps. BS EN 16472 also provides you with a step-by-step procedure for the method, enabling you to do the method correctly.
BS EN 16472 provides you guidance on apparatus, test specimens, exposure conditions, procedure, filtering of UV radiations, temperature control and test report, enabling you to assess the quality and life cycle of plastics and polymeric materials.
BS EN 16472 allows you to effectively determine a relevant lifetime estimate of polymeric materials exposed to natural outdoor conditions.
Thus, if you are a manufacturer of plastic products, compliance with BS EN 16472 guidelines can help you to assess your products to ensure that your products provide the best industry performance against natural weathering.
