During the receipt of a carbon steel plate of 25mm thickness were asked to calculate the maximum flatness and waviness knowing that, a specification ASTM A36 sheared edges, dimensions of 9000.0 mm x 2400.0 mm? how to check flatness and waviness in ASTMA6 ?
ASTM A36 makes part of ASTM A6. A6 is a broad specification that includes all structural steel specifications, A36 among them.

I've taken a look at A6. Table 13 states the permissible variations from flatness in carbon steel plates. Table 14 states the permissible variations in flatness in alloy steel plates. Table 15 states the permissible variations in waviness in all kind of plates.
As I said on my first posting, A6 is a broad standard that includes a number of more specific ones, A36 among them. On A6 it's also written that the particular requirements stated on any of the standards included, will prevail over the requirements stated on A6.
This means that if you measure flatness and waviness according to A36, you'll be on the safe side.

You will need to purchase a copy of ASTM A6.
You need a copy of the game rules to play the game. That's just one of the many standards, specifications, and codes one needs in order to play the game of "Inspection".
The employer is responsible to obtain and provide their employees the appropriate specifications, standards, and codes if they are contracting their services for inspection. If they cannot or will not provide their employees with the appropriate governing documents, the employee, i.e., the inspector, really can't do the job. If they can't do the work, they have no right to charge the client for services that are not rendered.
Purchasing the appropriate codes, standards, and specifications is one of the many costs of doing business. If one is not willing to buy the appropriate documents, they should not be offering their services to unsuspecting clients. To perform inspections without access to the appropriate reference documents is akin to a mechanic charging a customer for rebuilding an engine without actually doing the work. I believe that would be considered fraud in some circles.
