As above. You'll work on date of entry into service rather than date of manufacture. If your LOLER guy fails stuff based on date of manufacture you should challenge him on this. 

Unless the manufacturer stipulates the item's working life starts from date of manufacture of course

Any examples of this?

Some ropes, other textiles, webbing etc.  Depends on what the material composition is, where and how it's stored, tolerance of UV etc etc.  Like I said, depends on what the manufacturer stipulates.  I'll see if I can dig out a specific example - one certainly came up recently as that's what made me comment.

'The total maximum life of this rope (storage before use + lifetime in use) islimited to 15 years. In good storage conditions this product may be kept foras many as 5 years before the first use without affecting its future durationin use.'

 

That's for Yale Silverstreak prusik cord but it wasn't that example I was thinking of earlier.  In the above example, it is possible (albeit one would hope unlikely) that a rope could sit unissued on the shelf for 5 years and then almost immediately need to be retired.

Point I tried to make badly ?

You'd still have 10 years of use, even if it had sat on the shelf for 5 years before issue. If it was issued the day after manufacture you'd have 10 years of use. If it sat on the shelf for 14 years 364 days before issue you'd have one day of use.

 

All assuming correct storage and use.

Sorry yes you're right, bad example to choose - I'd taken the segment out of context of the rest of it.  That cord can do 10 years in service but has potentially 15 years from manufacture to being 'done'.

 

A better example would be a rope with a shorter overall life, whereby the time on the shelf eats more into the working life.

 

Like I said though, this wasn't the example I was thinking of.  I will find it - just can't recall it at the moment.

 

The point I was trying to make earlier is that we shouldn't assume date into service is by default the date to go by.  Date of manufacture can have an impact.

It does on hard hats.

 

Not a LOLER’d item, obviously.

Still not the example that I came across but this from Teufelberger ( for Ocean polyester) hopefully explains it well enough:

 

The product‘s service life may be up to 3 years from the day the product was first taken out of the undamaged light-protected package, and the product must be retired after no later than 3 years of having been used. It is assumed that the product is taken out of the package at the time of the purchase. We recommend that you keep the original sales receipt which is the proof of purchase. The theoretically possible total product life (correct storage prior to first removal + period of use) is limited to 5 years from the date of manufacture.

 

So in this example, you'd only get 2 years from your rope it you'd bought it 3 years after it was produced.  Noting also that if you get it home and unpackage it then that is in effect first use, not when it is actually first used (eg if it were bought for a rescue kit or other scenario where it wasn't used immediately).

 

There's an old thread here that discusses this issue:

 

In short, read the manufacturer's bumpf and go from that.
