I get it I do. but there are some problems.
1) The publishers of that "standard" don't have any authority to make such a declaration. They can say it, but that's it. It's just words in the wind.
2) There's no enforcement, so there can be no standard no matter how boldly they print the word "standards" on the book. Back to the authority problem.
3) We don't seem to care enough to make it our first and threshold question. We buy the nonconforming implements anyway. The consumer is the only authority and we seem disinterested. So there's no standard.
The dialog has to go like this:
Dealer: I have this Great XYZ Implement that'll do what you want."
Consumer: "Does it conform to ASE -278.6? If it doesn't, I won't touch it no matter how well built you say it is."
And that conversation Never takes place.
If manufacturers ignore it, then it is at best a suggestion.
I look at it like this, and for example, I offer the following:
There are all manner of "National" holidays that are most definitely not national. There is a book (recently there are two) published by a concern that records these "national holidays." The Wisconsin cheesemakers paid for a "national Wisconsin cheese day" so it's in the book, I could get one for me "National Raul-02 day"
But none of these days are actual real holidays, they are just entries in a book run by a private company. They exist for marketing purposes, so the Cheese Sales men can have something to talk about.
Standards like this are in the same class of things that are not in fact real.
Or stated another way Just because some bozo put it in a book doesn't make it a standard.
With no way to enforce it, it is meaningless.
Lubricating Oils meet the standards because they pay a stiff price for failing to do so. No one will buy them if they don't. And they can bask in the pride of adhering closely to the standards.
But Farm Implements? If we really cared, we'd boycott any manufacturer that doesn't adhere to 'em. It'd be the first question we asked our dealers. If Company X put out one single nonconforming impliment, the whole of America would regard their entire lineup with dark distrust.
But we don't do that, so in the real world, outside of those pages, there is no standard.
As an aside, most of the standards we have today arose from military acquisition. The military wouldn't buy a nonconforming product. Armies around the world tend not to get into farming.
