Q2: Can I use ASTM D36 instead of NBR 3021?

A: Technically, they are very similar. Legally? No. If a Brazilian contract specifies "NBR 3021", using ASTM D36 exposes you to liability in case of disputes or audits.

for environmental testing and specifies the need for specialized shock and vibration mounts Compliance
