What is BS EN 15720 – Requirements for shower trays of coextruded ABS/acrylic sheets about?
BS EN 15720 is a European Standard which discusses sanitary appliances. The main objective of BS EN 15720 is to provide best industry requirements and test methods to ensure shower trays are safe, reliable and effective at the point of use.
BS EN 15720 specifies the requirements for shower trays for domestic purposes made from crosslinked cast acrylic sheets conforming to EN 13559 with the aim of ensuring that the product, when installed in accordance with the manufacturer’s instructions, will provide satisfactory performance in use.  
BS EN 15720 is applicable to all sizes and shapes of shower trays.  
Who is BS EN 15720 - Requirements for shower trays of coextruded ABS/acrylic sheets for?  
BS EN 15720 on requirements of shower trays of coextruded ABS/acrylic sheets is relevant to:  
- Manufacturers of sanitary appliances
- Manufacturers of shower trays 
- Quality control and testing personnel 
- Mechanical engineers

Why should you use BS EN 15720 - Requirements for shower trays of coextruded ABS/acrylic sheets?  
Acrylic sheet shower trays are used in homes, hotels, accommodation for students, hospitals and similar buildings, except when special medical provisions are required. However, these trays need to adhere to best industry requirements for effective performance and functionality and to prevent unwanted overflows and spills.
In this regard, BS EN 15720 provides requirements for materials, dimensional and geometric deviations.
BS EN 15720 also walks you through test methods that demonstrate whether your shower trays are capable of withstanding temperature changes and impact, without causing product failures and damages. This further helps in keeping the tray intact from the surface of the bathroom when in use with variable water temperatures.
BS EN 15720 also provides guidance on the geometric deviations, temperature change resistance, resistance to external impacts and determination of deflections to ensure of optimal performance and effectiveness of the product.
The determination of defections in accordance with BS EN 15720 is intended to simulate effect of loads on different parts of the shower tray whilst the shower tray is in use.
As a result, if you are a manufacturer of ABS/acrylic sheets shower trays, adopting BS EN 15720 requirements can help determine whether your products are reliable and effective for use.
