Specifications Organizations:

ASTM
ASTM is a not-for-profit organization which sets forth standards on many facets of manufacturing.

ASTM standards regarding solder specify composition, impurity limits, and dimensional tolerances, and are intended primarily for non-electronics related soldering.

While ASTM standards are voluntary, they are often specified in contracts and purchase orders.

J-STD-006
The “J” Standard is a quality control specification pertaining to solders for electronics grade solders, both with and without flux.

QQ-S-571E
