i tried this thread on the normal forum to little response so thought i'd throw it out again to the desighners instead -Sorry to start yet another tread on the subject of ties but i didnt really want the possible answers getting lost in an old thread also it possibly required more detailed response
whilst looking at a tecspec sheet for a rubber reusable insert for brickwork from Leach's came accross this sentance that confused me a little and then made me ask the forum -so here goes
"The NTA anchor is desighned for use in accordancewith BS5973(1) AND THE NASC TG20:06 Technical Guidance on the use of BS EN12811/1"
is this a really old guidance as i never used TG20:06 ?, would it not have been updated by the introduction of 20:08 which i thought was instead of
BS5973- and therefore NASCs guidance TG4:11 to which i cannot find this type of anchor- although a phrase"when choosing anchors preferance should be given where possible,to anchors which have been awarded an ETA(8) as these will have been exhausively tested blah blah blah"
so the other question is whats an ETA(8)
also noticed on 4:11(6.1) reguarding preliminary/proof testing- as there are no manufacturers load data for the base material (brick) could i just do my own proof test,logging the results and if all test ok procede to use them
many thx for you replys
