What is PD CEN/TR 16886 - Properties of masonry products about?
PD CEN/TR 16886 is the international standard on masonry which is a durable material that allows for a variety of reliable and aesthetically pleasing finishes as well as to fill the gaps between blocks in the construction.
The purpose of PD CEN/TR 16886 is to exemplify how a statistical tool can be used in practice.
PD CEN/TR 16886 should not contradict nor extend the scope of the work and role of a Notified Body, nor impose additional burdens on the manufacturer, beyond those laid down in the Construction Products Regulation and the product standards.
Mechanical and other properties of building materials and components are in the report described by random variables with a certain type of probability distribution.
A normal distribution (Laplace-Gauss distribution) may be used to approximate many actual symmetrical distributions. When a remarkable asymmetry is observed, then another type of distribution reflecting this asymmetry should be considered, leading to a more complex method to demonstrate compliance with the product standard.
More information on the normality test of Shapiro-Wilk is given in Annex D.
Who is PD CEN/TR 16886 - Properties of masonry products for?
PD CEN/TR 16886 on masonry products is useful for:
- Builders
- Architects
- Road contractors
- Manufacturers of masonry cement
- Manufacturers and suppliers of cement mortar
- Quality control inspectors
Why should you use PD CEN/TR 16886 - Properties of masonry products?
Modern masonry products include Portland cement plaster, cement for masonry, mortars, concrete block, and clay brick that can be used on the interior or exterior of structures in a wide range of environments.
PD CEN/TR 16886 provides compliance for masonry products with the requirements and with the declared values for the product properties by carrying out both determination of product type by type testing and factory production control.
PD CEN/TR 16886 navigates you through the statistical evaluation of the factory production control system that includes checking procedures mainly related to the process only, the finished products only or a combination of both.
PD CEN/TR 16886 gives details on testing the finished product in FPC with two alternative test methods namely,
- Control method A: Batch control
- Control method B:'Rolling' inspection
Product type determination is specified in PD CEN/TR 16886 based on the reference test methods and the sampling procedure for type testing.
Overall, the test methods described in PD CEN/TR 16886 allows you the evaluation of different properties at the different stages of the factory production control (FPC) with the aim to minimize testing costs for the manufacturer and to ensure that the requirements are fulfilled.
As a result, you may get high-quality masonry materials for building your structure available in a variety of colours, sizes, textures, and patterns to enhance their aesthetic appeal while also controlling sound, resisting fire, insulating against daily temperature variations and having a longer lifespan.
