What is BS EN 12697-14 about?  
BS EN 12697-14 is the 14th part in a multi-series of European standard that is applicable to the bituminous mixtures.
BS EN 12697-14 describes a test method for the determination of the water content of samples of bituminous mixtures. The test method is suitable for checking conformity to a product specification, where required.
Who is BS EN 12697-14 for? 
BS EN 12697-14 on the bituminous mixture is useful for: 
- Manufacturers and suppliers of bituminous mixtures
- Suppliers of construction materials
- Construction and civil engineers
- Contractors
- Road maintenance authorities
- Testing laboratories
- Designers for mixtures
Why should you use BS EN 12697-14?  
Bitumen when used as a binder in asphalt, is widely used in the construction domain for road construction, paving and roofing. It strongly binds other pavement components together and provides a smooth and levelled surface. Water content plays a vital role in determining the right moisture content that does not make the mix too soft or too brittle.
A test technique for determining the water content of samples of bituminous mixtures is described in BS EN 12697-14. This will make it easier for you to dissolve bitumen and distil the solution to recover the water.
The right water content in bitumen is vital to prevent excessive foaming. In this regard, compliance to test methods under BS EN 12697-14 will help you ensure quality and performance of the construction materials that enhance the durability and service-life of the roads and pavements.
What’s changed since the last update?
BS EN 12697-14:2020 supersedes BS EN 12697‑14:2000, which is withdrawn. BS EN 12697-14:2020 includes some technical changes with respect to BS EN 12697-14:2012. These include: 
- The title no longer makes the method exclusively for hot mix asphalt
- [ge] NOTEs modified or adjusted to the normal text where appropriate according to ISO/IEC Directives
- European foreword: reference to the product standards for the applicability of this test method deleted
- [Clause 2] reference to pr EN 12697-27:2000, Bituminous mixtures - Test methods for hot mix asphalt
- Part 27: Sampling replaced by EN 12697-27 Bituminous mixtures - Test methods – Part 27: Sampling
- [Clause 6] reference to pr EN 12697-27:2000 replaced by EN 12697-27
