/ gear age identification
It varies between manufacturers, so there is no one answer. What are you trying to date?
Hi. I run sessions at a variety of places & some are supposed to adhere to an age related retirement of (their) gear ( with my own kit it's done by condition & my knowledge of its use). Sometimes it looks a bit suspicious. I thought that most manufacturers use a similar system that's based on numeric ref for weeks of the year etc. If I'm not happy with the kit I don't use it, but it would be good to be able to tell them it needs retiring based on their own rules as well as mine.
DMM stamped y92 on some of my krabs.

I've had to do this sort of thing before, and i've always found it takes quite a bit of effort. There are so many different systems out there.
I'd have to check, but I know that DMM and Wild Country do both use (or have done in the past) a system as you describe on some bits of kit (software) but krabs may use a different system. If I remember correctly, the DMM harnesses I was using had a 3 digit code on them that was week (1st 2 digits) and year (3rd digit). I think Wild Country have details on their website, but I think that I had to ask DMM for advice. Other brands may not be as easy.
DMM info here:
For Beal ropes, the last two digits at the end of the long number printed on the manufacturers label are the year of manufacture.
Petzl now use a date code as part of their uniques identifier as follows:
Petzl serial number changes
1988+ e.g. 035 88 means manufactured 35th day of '88
1995+ e.g. 95 035 I means manufactured 35th day of '95, Quality Assurance letter I
2006+ e.g. 06 035 AB 3261 means manufactured 35th day of '06, unique code AB3261
For Petzl helmets made up to 2009 the code is etched on the right hand front-rear adjuster below the ear; 2009+ it is on a sticker on the inside of the helmet.
Hope this helps,
