HistoryThe B&ES TR/19 guidelines were introduced in 2005 by updating the old TR/17 guidelines which were in effect from 1998. In 2014, TR/19 was updated to reflect changes in European standard BS EN 15780:2011 – Ventilation for buildings – ductwork – cleanliness of ventilation systems.[4] TR/19 was updated to reflect the benchmarks and testing protocols as contained in BS EN 15780.[5][6] The prime changes in TR/19 2005 and 2014 versions are introduction of a CQC, testing protocol and test equipment specification, separation of new duct systems from existing systems and introduction of the RRFSO.[5] References1. ^{{cite web|url=http://www.b-es.org/b-es-connections/technical/compliance/it-pays-to-be-clean/ |title=It pays to be clean |publisher=B&ES |accessdate=7 May 2015 |deadurl=yes |archiveurl=https://web.archive.org/web/20150116020119/http://www.b-es.org/b-es-connections/technical/compliance/it-pays-to-be-clean/ |archivedate=16 January 2015 |df= }} {{DEFAULTSORT:BandES TR 19}}2. ^{{cite web | url=http://www.pro-ductclean.com/tr19-standard.asp | title=Guide to Good Practice: Internal Cleanliness of Ventilation Systems | publisher=PDC | accessdate=7 May 2015}} 3. ^{{cite web|url=http://environmentalsciencesociety.org/2013/10/22/fire-risk-the-problem-tr19/ |title=Fire Risk – TR/19 & Informed Decision Making – Ventilation and Environmental Health Risk Assessment – WYG Group Consultant Case Study |publisher=Environmental Science Society |date=22 October 2013 |accessdate=8 May 2015 |deadurl=yes |archiveurl=https://web.archive.org/web/20150214191338/http://environmentalsciencesociety.org/2013/10/22/fire-risk-the-problem-tr19/ |archivedate=14 February 2015 |df= }} 4. ^{{cite interview | title=TR/19 update--key concerns addressed. | date=2014 | last=Norman | first=Richard | PMID=25282986}} 5. ^1 {{cite web | url=http://www.indepthhygiene.co.uk/tr19-ductwork-cleaning-guideline-changes-2014 | title=Comparison of B&ES TR/19 Ductwork Cleaning Guidelines Changes Between 2005 & 2014 Editions | publisher=Indepth Hygiene | accessdate=8 May 2015}} 6. ^{{cite web | url=http://www.hvnplus.co.uk/news/bes-publications-launches-the-updated-tr/19/8665834.article | title=B&ES Publications launches the updated TR/19 | publisher=H&V news | date=17 July 2014 | accessdate=8 May 2015}} 2 : Heating, ventilating, and air conditioning|Building engineering |
