Mestek Machinery announced in March that the sheet metal equipment maker is now approved by the International Organization for Standardization (ISO).

The company has been certified as compliant with ISO 9001:2008 and accredited by NSF International’s strategic registrations program. It had to undergo a quality-management evaluation and audit by NSF officials.

The certification means customers can be sure Mestek is committed to the highest efficiency and customer satisfaction, the company said.
