STANDARDS

British Standards Institute (BSI) work with ISO and other standards groups to ensure the standards available in the UK are fit for purpose and reflect current and best working practices.  A quick check on the BSI website shows there are over 80 standards documents that relate to gears.  While some of these are old and maintained for historical purposes, many are new or recently revised to reflect the changing needs of our industry.

We have created a portal for BGA Members to view all of the latest technical developments which are currently taking place in gear standards. Click the button below to go there now.

Background

The standards are maintained by a technical committee of volunteers who offer their services free of charge to BSI and ISO to ensure the standards are fit for purpose.  There is a perception that these standards ‘are set in stone’ and do not change but when problems are noted with implementation of existing standards, these are reviewed and addressed by the relevant technical committee.  Similarly as technology and technical understanding develops, standards are revised but the technical committees must be mindful that changes also incur costs for industry and thus a great deal of care is needed to minimise this while maximising the benefits.

The BSI technical committee MCE 5 is responsible for gears.  A series of working groups or panels covering a range of technical fields support work undertaken by the ISO

A summary of the technical committees is provided below:
