Convener and secretary’s page
DATE OF NEXT MEETING:
7-8 April 2020
NEW MEETING DATE: 13-14 May 2020
Because of Coronavirus (COVID-19) this meeting will be held online only.
Meetings are usually held twice a year, typically in (approximately)
March April and October November. In order to guarantee that reports are reviewed at the next meeting, they should be uploaded to the TG1 website by the end of January February (for the “March” “April” meeting) and the end of August September (for the “October” “November” meeting). If you are not a TG1 member, you can send reports to David Gil-Moreno or Dan Ridley-Ellis (after first asking for the report numbers to use).
Important, in order to correctly prepare reports you will need:
– The TG1 sampling guidelines (download version dated 12th October 2016)
– The TG1 decision list (download version dated 22 October 2019)
– The file naming convention, adopted at the October 2018 meeting.
– The description of the TG1 workflow and acceptance procedure (download version dated 7th March 2017)
For a brief explanation of what TG1 does, and why the decision list exists – see this blog post, and this journal paper (doi:10.1007/s00107-016-1034-1). Note, however, that the journal paper predates the current (2018) version of EN14081-2 and several of the important calculation procedures are changed.
For a list of grading machines (approved for machine control in Europe to EN 14081), see this blog post. Other kinds of machine may be used for output control.
It was agreed (2017/03) that TG1 expects the latest versions of the standards are used as soon as they are made available by CEN (unless justified otherwise). This may be before they are published by all individual National Standards Bodies. Check the CEN/TC124 work programme for updates and contact the TG1 convenor or secretary if in any doubt.
