Ok we all know what Ty-wraps we are allowed to use and which we arn't, but can anyone actually tell me where this is laid down on paper? Much appreciate any help. :S
Surely the ones you can demand are "MoD approved"? I know whilst doing equipment installation, the specific cable ties (Ty-raps) are named by NSN.Ok we all know what Ty-wraps we are allowed to use and which we arn't, but can anyone actually tell me where this is laid down on paper?

I'm an ex RAF DF and whilst i was in i never needed to see anything on paper, now however i'm working on a project where the MoD is the customer and theres a multitude of nationalities building pieces for the project. However they didnt get the "Use internal Ty's and i'll kick your ar$e into next year" brief, and i need to find something official to drop in their in- trays as some are not only useing the dreaded internal Ty's but some are even useing ones with a metal tang, unless i can find something official to show them its going to end up with you guys having to replace them all as soon as you recieve the kit. Better to find a piece of paper now i would have thought...
There must be some form of policy statement or safety report detailing which ones to use and why. I have trolled the JAP and exhausted all official channels so now i come to the people who do the job.
Can you contact the IPTs who are to be the customers for this kit and get them to send you their directives?
I would suspect there will be a Mil spec number for Ty-Wraps, my thinking in that is because if we have to have a mil spec for a washer which cost 20 times what the same washer would do in a DIY shop, so therefore it should be written down which Ty-wraps are authorised for use.
Not much help I know, but all aircraft 'C' stores will have to have been vetted at some point to be used.
Defstan00-970 part 1/5, section 6
6.6.55 Interconnecting electrical wiring shall be installed
using components, (e.g., terminal posts, terminal blocks,
terminal junction modules or electrical connectors) and
methods of support (e.g., cable ducts, conduit, open looms
in conjunction with cable ties and cleats) that meet with
specifications approved by the Aeroplane Design
Authority and agreed with the MOD Integrated Project
Team Leader (IPTL).
I think BigRed is correct about the timing, this directive came in about the time Kapton was being rolled out.
I havent managed to find a definitive answer, although this suggests its down to the IPT:
Alternatively, BS EN 4056-001:2006 deals with this directly, there are references to British Standards within some Defstans.
The question is, where did the IPTs get the directive from? I have asked a couple of desk officers and a former wiring husbandry rep and havent found the answer.
