For a subcontractor to be aware, he would have to look at this part of the plan and ask questions about the general tolerances to be applied to the piece :-(
They are still great to have kept ISO 2768-1 but replaced ISO 2768-2 with this new 22081. A change of version would have been simpler.
Does this mean that the system of capital letters has been replaced??
A priori the modifications are:
"
The main changes compared to ISO 2768-2:1989 are as follows:
— tools have been added to specify a general geometric specification and a general size specification;
— the rules for the application of a general geometric specification and a general size specification have been clarified
"
Having taken a look at the new standard, the system changes completely and we abandon the letters H, K and L to put something clearer but which is not valid whatever the plan (since the tolerances no longer follow the dimensions of the part but are fixed).
Or you have to put the table on the plan or create an external document to specify the tolerances.
In the end, each client will create its own standard.
I pity the subcontractors who will work with X specs of X customers as a result....
We have to define our own standards, I think we'll start again with the standards of the previous standard defined in the cartridge of our plans.
But I can already see the situation where we will define a different standard on one of our designs, and no subcontractor will notice the difference.
Between those who deal with business without looking in detail at our specs, (and once done, they realize that they can't meet our requirements) those who have different specs for each client, and those who are picky who will take months to process a request for quotation to take into account all the specific specs and the associated controls;
We will face the same situation as currently, I don't see how we are progressing with a new standard like this, apart from cluttering up the cartridge with our standards which will probably go unnoticed by our subcontractors.
The next step is also to redefine our dimensional tolerance standards in our cartridge?
Thank you for putting the post back up. To date, we have not changed our plans.
We remain on the ISO 2768-1 and 2 standards which remain known to all.
We plan for the next modification of our cartridges to integrate a tolerance framework (same as the tolerance of the ISO 2768-2 standard), hoping that it will not only be present for aesthetics. We have small parts, the current general geometric tolerances remain in line with our needs most of the time.
With regard to subcontractors, the discussion was not addressed.
