Latest Information for Members The latest service bulletin for NTDA members gives advance notice of the latest revision of the British Standard for the repairing of tyres – BS AU 159f. The Standard was last revised in 1997 and the latest version is currently under review. A draft document is expected to be issued shortly and comments from the trade will be welcomed before the final draft of the Standard is published. Among the changes are likely to be (for the first time) recommendations on repairs for agricultural tyres, plus there will be a definition of and advice on the repairing of self-supporting runflat tyres. With an increasing number of cars carrying a ‘mobility kit’ of a can of sealant and a compressor instead of a spare tyre, the new Standard will contain advice on these temporary repair products.

Diary Dates
Black Mark For Thomas Cook At its meeting at the end of February, one of the topics discussed by the NTDA Council was a TV advert for holidays. The advert, for Thomas Cook, shows a queue of people waiting to board a Thomas Cook coach. A man then crouches down near the rear wheel and removes the tyre valve with pliers, watched by a child and several adults. As he walks away, smiling, the voiceover says “holidays you won’t want to return from”. A piece of harmless fun? Over 100 viewers didn’t think so and they complained to the Advertising Standards Authority. Some complained that the ad was irresponsible for condoning and encouraging crime or anti-social behaviour, others that it encouraged behaviour prejudicing health and safety. Some thought that it could cause children to emulate the man’s behaviour and a few thought that the ad was offensive because it showed actions that might lead to a traffic accident and would cause ‘serious offence’ to victims of coach crashes and their relatives. So where does the NTDA come into this? The Association was contacted by the ASA and asked to comment on the advert from a professional viewpoint. Following discussion, Council decided that the advert was irresponsible from a Health and Safety point of view and that anyone removing a valve in such a way would be risking potentially serious injury. This was reported to the ASA and the ball is now in their court.
It is worthwhile pencilling in a couple of important dates in the NTDA’s 2013 calendar. Firstly, the Westlake/NTDA Golf Day will be held on Wednesday 24th July 2013 at Brocket Hall, Herts. Secondly, the NTDA’s 84th Annual Dinner and TAFF Awards presentation for 2013 will take place on Wednesday 16th October at the Hilton Metropole, NEC Birmingham. Further details of these events will appear in NTDA News nearer to the dates that they are taking place.
