What is BS EN 13108-21 - Factory Production control requirements for bituminous mixtures about?
BS EN 13108-21 specifies both quality and factory production control requirements for use during the manufacture of bituminous mixtures intended for use on roads, airfields, and other trafficked areas. Additional testing carried out within contracts is beyond the scope of BS EN 13108.
Note1: The Factory Production Control will be applied to European Standards for bituminous mixtures if CE-marking under CPR is applied. BS EN 13108-21 may also be part of quality control in situations where CE-marking does not apply. As such, manufacturer's factories notified to issue CE Marking for production of bituminous mixtures should not require duplicate or additional auditing for those situations where CE-marking does not apply.
Note2: BS EN 13108-21 is applicable to the control of bituminous mixture where the constituents and target composition are known and have been shown by means of Type Testing to comply with all appropriate specified compositional, performance related or performance-based requirements in EN 13108‑1 to ‑7 and EN 13108‑9.
Who is BS EN 13108-21 - Factory Production control requirements for bituminous mixtures for?
BS EN 13108-21 on factory Production control requirements for bituminous mixtures is useful for:
- Manufacturers and suppliers of bituminous mixtures
- Construction industry
- Civil engineers and contractors
- Road, pavement, and highway construction companies
- Repair and maintenance companies
- Local authorities
- Testing laboratories
Why should you use BS EN 13108-21 - Factory Production control requirements for bituminous mixtures?
Processes, as well as process control systems, are continuously being developed which means that new systems for Factory Production Control will be introduced and implemented. If a manufacturer is able to demonstrate that his process control system is able to secure the fulfilment of the requirements on the finished products in a satisfactory way then alternative minimum frequencies of inspection and testing may be acceptable. The basis of BS EN 13108-21 is that of the control of constituents, composition, and mixing by regular sampling and inspection.
BS EN 13108-21 specifies both quality and factory production control requirements which are put in place to allow a manufacturer to maintain consistency in quality and to keep records of non-conforming products, processes, and materials, in order to make improvements.
What is changed since the last update?
BS EN 13108-21:2016 supersedes BS EN 13108-21:2006 which is withdrawn.
BS EN 13108-21:2016 includes some technical changes with respect to BS EN 13108-21:2006.
These include:
- Update to align with other parts of EN 13108 series, test methods and CPR requirements
- New guidance on non-conforming product, as part of FPC, and system non-compliance on audit
- “Constancy of performance” generally replaces “conformity of product”
- Clarify “additional characteristic” sieves for DoP purposes and “optional” sieves for FPC
- Incorporate multi-plant, single FPC system approach for audit
