Quality Standards

At SHERNI, we pride ourselves on being the sole organization in India dedicated to manufacturing High-Security Combination Locks, endorsed with both ISI certification from India and UL Certification from the USA.

Our commitment to quality begins with our highly skilled workforce, meticulously trained to uphold the stringent standards set forth by our Quality Management System.

To ensure the unwavering maintenance of these standards, we’ve developed cutting-edge endurance testing machines. These machines rigorously subject our Mechanical Combination Locks and Key Locks to 20,000 cycles, adhering strictly to international and BIS norms. You can witness this meticulous testing process in action through the attached video.

Furthermore, our dedication to quality extends to our in-house testing facilities, which comply with BIS norms. These facilities include equipment for Salty Spray testing, Humidity Chambers, Vibrating machines, Aging Stress Distortion Chambers, Endurance Testing Machines, Load testing, and more—all calibrated to meet the exacting standards of ISI certification.

At SHERNI, quality isn’t just a goal—it’s a commitment woven into the very fabric of our organization, ensuring that every lock we produce meets the highest standards of security and reliability.”
