Annual Guide 2019 I SOURCE TESTING ASSOCIATION
ISO standards are accepted on a case by case principle; it is not mandatory for a member country in the European Union (EU) to adopt a standard.
CEN standards must be implemented by member states of the EU. If a confl icting standard is in existence, then this must be withdrawn.
Understanding how
standards numbers work Figure 1 shows how standards are adopted in the UK and published by British Standards Institute (BSI).
1. Should a standard be developed for example in the UK by BSI it will be prefi xed by BS e.g. BS 3841-1:1994 Determination of smoke emission from manufactured solid fuels for domestic use.
2. When a standard is developed and published by CEN it is prefi xed with EN and when introduced in the UK it will become a BS EN document e.g. BS EN 1911:2010 Stationary source emissions – Determination of mass concentration of gaseous chlorides expressed as HCl and as stated above any confl icting standard must be removed. A standard can be developed by CEN or ISO under a joint agreement and then it is published by CEN and ISO with a prefi x EN ISO and in the UK it then becomes an BS EN ISO prefi x e.g. BS EN ISO 23210:2009 Stationary source emissions – Determination of PM10/PM2.5 mass concentration in fl ue gas. A national foreword is added to the standard to indicate its scope of applicability and to highlight any UK specifi c concerns.

3. When a standard is developed by ISO it is prefi xed ISO and should this be adopted in the UK it becomes BS ISO e.g. BS ISO 25597:2015 Stationary source emissions – Test method for determining PM10

Standards developed and published by CEN are generally accepted as being the most robust. However, other standards are still important, as there are substances that are not, as yet, covered by CEN Standards. The choice of the method is often dictated by the requirements of EU Directives, i.e. Industrial Emission Directive (IED), where, for example, the use of CEN standards is mandatory. If the standard is not dictated by mandatory requirements, then monitoring standards should be used in the following order of priority as given in the European IPPC Bureau’s Reference Document (
http://eippcb.jrc.ec.europa. eu/) on the General Principles of Monitoring:
1. EN standards 2. ISO standards, other international standards, national standards 3. Validated laboratory-developed and non-standard methods
The intended application of the standard method must always be taken into account; for example, a CEN method may be less suitable than another less-rigorously validated standard method if the application is not one for which the CEN method was developed.
