Are MIL specifications out of date?

[mmolt]

Does anyone use MIL specficiations anymore?

Thanks,

Mike

We occasionally use them when no other industry standard can be found. I try to avoid them like the plague because most vendors automatically raise their price when they see a MIL spec.

MIL specs are still the main source a lot of items. Even other standards will reference them. It depends on which area you are in. If you are using materials or documentation, I wouldn't personally callout the MIL. However, if talking about hard shell shipment cases, I might refer to them.

They are slowly being replaced mostly by ASME. If you look them up

http://assist.daps.dla.mil/quicksearch/,

it will tell you what they are replaced with and if they can still be used by new designs.

Find the attached to see what I'm refering to. I'm wondering if there would be a better specification for the printing than a MIL spec.

There are replacments for these specs.

The drawing lists ANSI Y14.5M. Any reason that it has not been updated to the 1994 version?

As others said a lot of the MIL standards are gradually being replaced or at least supplemented by other standards, primarily ASME for this type of thing.

Normally a google search will turn this up.

Looks like the replacement for MIL-I-43553 may be a work in progress.

One other point on the drawing, you ref ANSI Y14.5M. Current spec is ASME Y14.5M-1994 if that's what you mean to refer to. By putting ANSI are you deliberately referencing the 1982 version, if so may want to add -1982 to make this clear.

KENAT, probably the least qualified checker you'll ever meet...

Ringman is correct. Clarification is needed.
Also, if a silkscreen house is doing this work, I don't think they will understand the MIL specs. Maybe split the dwg into two, one for fab and the other for silkscreen? Unless you do it all in house.

We will update the ANSI spec...but this is more about the MIL specs.

If I understand you guys correctly, there isn't a non-MIL spec for the print yet? This is a purchased part.

There are a couple of Mil STD plating specs that don't seem to have an industry equivalent, such as anodizing.

Mike,
Did you search for your MIL spec in the link I attached above? It will show you equiv specs.

Like I said, do a google search, that's where I got the link in my previous post from.

Obviously can't be 100% sure just based on this but it's a good indication.

Silkscreening can go on a separate artwork sheet that doesn't even need to be on the actual drawing itself.

Matt is correct. That is how I do it. I send silkscreener DXF file and a picture of what it should look like.
