The welding filter included is not tested to ISO 12312-2:2015 compliance, as it is originally intended for welding and the ISO 12312-2:2015 is a specific set of guidelines for solar eclipse viewing products. That being said, the American Astronomical Society recommends a shade 12 minimum welding lens for safe viewing, and up to Shade 15 depending on comfort level, which can be referenced in the last paragraph of this link: https://eclipse.aas.org/eye-safety/is...
