What is BS EN 14758-1- PP-MD piping specification about?
Polypropylene with mineral modifiers (PP-MD) is made of Polypropylene and the middle layer is made of mineral-filled polypropylene compounds (PP-MD). BS EN 14758-1 discusses plastic piping systems for non-pressure underground drainage and sewerage.
BS EN 14758-1 is the first part of the multi-series, and specifies the requirements for solid-wall pipes, fittings, and the system of piping systems made from mineral modified PP-MD in the field of non-pressure underground drainage and sewerage outside the building structure (application area code "U"), and non-pressure underground drainage and sewerage for both buried in the ground within the building structure (application area code "D") and outside the building structure.
This is reflected in the marking of products by "U" and "UD".
BS EN 14758-1 is applicable to PP-MD pipes with or without an integral socket.
The fittings can be manufactured by injection moulding or be fabricated from pipes and/or mouldings.
Requirements and limiting values for application area code "D" are given separately in tables.
Note 3: Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex B can be used with pipes and fittings conforming to BS EN 14758-1 when they conform to the requirements for joint dimensions given in Clause 6 and to the requirements of Table 13.
Who is BS EN 14758-1- PP-MD piping specification for?
BS EN 14758-1 on PP-MD piping specification is useful for: 
- Plastic piping system component manufacturers and suppliers
- Product design engineers
- Quality control and testing personnel
- Contractors
- Civil engineers
- Local authorities
Why should you use BS EN 14758-1- PP-MD piping specification?
PP-MD pipes are suitable for drainage, soil and wastewater discharge, at low and high temperatures. BS EN 14758-1 specifies details for the test parameters for the test methods referred to in BS EN 14758-1. BS EN 14758-1 covers a range of nominal sizes, and a range of pipe series/stiffness classes and gives recommendations concerning colours.
In conjunction with Part 2 and Part 3, EN 14758 is applicable to PP-MD pipes and fittings, their elastomeric sealing ring joints, and joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for non-pressure underground drainage and sewerage.
BS EN 14758-1 provides you with, general characteristics, geometrical characteristics, mechanical characteristics of pipes, physical characteristics, performance requirements, and marking for PP-MD piping material.
The assessment methods provided in BS EN 14758-1 ensures the conformity of materials, products, joints, and assemblies.
With the compliance of BS EN 14758-1, you can enhance the efficacy of piping systems for non-pressure underground drainage and sewerage; and manufacture a standardised product.
