ASTM stamped material
ASTM stamped material
(OP)
ASTM standards become legally binding only when a government body references them in regulation or when they are stated in the contract. Any item that is produced and marked as conforming to an ASTM standard must meet all applicable requirement of that standard.
How it is insured that a material having ASTM stamp is according to ASTM standards. Either the manufacturer have ASTM certification or there is some other method to insure the reliability of ASTM stamp?

Bottom line, you have to work with suppliers who understand what you need and have developed a trusting relationship with. If you find someone who is intentionally falsifying documents, don't do business with them, and let everyone know why.

This makes them liable in case of problems.

If you are buying to an ASTM you have hte right and obligation to inspect enough to make sure that you are getting what you asked for.

You may refer to EN, DIN or ISO (All the three are essentially the same).
It appears you are a purchaser or the user who is afraid that the supplier would cheat you with spurious supply.
These certification standard caters to such needs.
You have to decide as what kind of inspection documentation you require. If it is oK for you to have a basic compliance certificate than go for 2.1, if you want all properties to be certified by a competent lab (With in the manufacturer's works) then you go for 3.1 B. If you do not beleive the manufacturer then go for 3.1C , where in you can appoint a third party to go and inspect and certify.
It all depends on what you want (How paranoid you are)
RE: ASTM stamped material
Watch out with the standard EN10204 (the 2.1, 3.1.B and 3.1.c. certificates referred to by bmoorthy). This standard and certificates only state that the material was sampled, tested and inspected according the specification of the material which you have ordered. So NOT manufactured!! I have been told that european standarisation body wanted to change this standard to incorporate the manufacturing, but the steel manufacturers oppose to this. Probably because of legal implications. Don't think this is not important; as a surveyor I've come across some (luckily not much) examples in which the manufacturer did not do the correct heat treatment mentioned in the specification.

Is it availab?
Many thanks
RE: ASTM stamped material
ASTM standards, like any other standards, are simply lists of requirements. Someone issuing a report saying the material meets a certain ASTM standard is doing exactly that--stating that they've run the tests required by the standard and that the requirements were met. That statement is as reliable or as unreliable as any other statement that producer might make, and a signature and notary stamp has the same effect on that piece of paper as it would on any other.
There is a similar issue with the AWS A5.X standards for welding consumables. AWS doesn't audit the electrode manufacturers, and customers generally don't send out independent inspector or auditors either.

ASTM specifications are the minimum requirements for products. They also require that the purchaser provide specific information/requirements.
Are you a meterials user?
Are you a member of ASTM? Membership costs less than one of the books, and then they give you one. You don't have to attend the meetings, just vote on the ballots.
It is your responsability to know what you are buying. That is why the specs contain inspection statements.
If you have doubt, require 10204 3.1.c. This requires third party testing to at least verify the required chemistry and properties.
