The Armstrong Smart Access Lock Your Home Security Solution

An Armstrong Smart Access lock is the first line of defense for your home. It’s not just a piece of advanced technology; it's a critical security component that must function flawlessly every single day, regardless of the weather.

Our customers trust our locks to withstand everything from intense heat and humidity to the harsh, salt-laden air of coastal regions. To guarantee this long-term reliability, every Armstrong Smart Access lock undergoes one of the most rigorous durability trials in the industry: the Neutral Salt Spray (NSS) test.

What is a Salt Spray Test?

The Neutral Salt Spray test is an accelerated, standardised method of simulating corrosion. In essence, it allows us to replicate the damaging effects of many years of severe environmental exposure in a compressed time frame.

This test is non-negotiable for us. It is the only way to confidently verify the durability of the protective finishes, external casings, and critical internal mechanisms of our smart locks.

The Armstrong Smart Access Testing Protocol

Our quality assurance protocol is meticulous and adheres to strict international testing standards. The process unfolds in several key stages:

1. Component Preparation: Before the test begins, samples of our smart locks—including keypad housings, handle components, and internal metallic mechanisms—are thoroughly cleaned to remove any surface contaminants.

2. The Test Chamber: The components are then placed in a sealed, state-of-the-art testing chamber.

3. Simulated Corrosive Environment: Inside the chamber, the locks are exposed to a continuous, fine mist of a 5% sodium chloride (salt) solution. This is maintained at a constant, elevated temperature of 35°C to create an intensely corrosive atmosphere, far more aggressive than any typical outdoor environment.

4. Endurance Testing: Our smart locks are required to endure this harsh environment for extended periods, often 1000 hours or more, to simulate years of exposure.

5. Meticulous Inspection: After the test cycle is complete, the components are removed, carefully rinsed, and dried. Our engineering team then inspects every piece under magnification for any sign of corrosion, such as rust, pitting, blistering, or any degradation of the protective finish.

Why We Do It: Our Commitment to You

We subject our locks to this punishing process for a simple reason: reliability is not optional.

Many smart locks look impressive on the day of installation, but they can quickly fail when their inferior finishes wear away and moisture begins to corrode the sensitive electronics and moving parts within.

The salt spray test is our guarantee to you. It proves that an Armstrong Smart Access lock is built to last, providing your home with robust, reliable, and intelligent security for years to come, no matter where you live.
