Air Contaminant Testing

Air Contaminant TestingMixed Flow Gas Air Contaminant Testing

Atmospheric contaminants can affect how equipment functions. The three descriptions -- air contaminant testing, mixed flow gas testing or pollutant gas testing -- all refer to exposing a test subject to simulated atmospheric contaminants and measuring their effects.

Telecommunications equipment and surface coatings are the most common targets for air contaminant testing. Atmospheric contaminants cause various changes on the surfaces of metals, most of which promote corrosion and can affect how the equipment functions. Corrosion degrades the ability of coatings to protect the surfaces they are meant to protect.

Airborne contaminant tests on telecom are accelerated tests that simulate what the equipment would experience in ten years or longer in a central office (CO). The standard for telecom and network equipment building systems (NEBS) GR-63-CORE outlines a way to test critical central office equipment. The NEBS standard includes mixed gas flow test and hygroscopic dust test. These trials include exposing the test subject to coarse dust particles, fine particles, water soluble salts such as sulfates and nitrites, volatile organic compounds, sulfur dioxide, hydrogen sulfide, ammonia, oxides of nitrogen, ozone and gaseous chlorine.

Simulating air contamination is no simple process. Test pollutants need be administered in precise quantities, measured in microns or parts per billion (ppb), and only purpose-built equipment provides the right volume exchange and airflow rate for valid, repeatable results. NTS has the equipment necessary to perform air contaminants testing, including a large capacity chamber able to handle full size telecommunications racks.

Airborne contaminants also destroy building materials, protective coatings, rubber, plastics and metals. In conjunction with humidity, UV light, thermal changes, salt spray and fog, atmospheric particles and gases accelerate the aging of automotive, military and industrial equipment.

NTS provides air contaminant testing to help you evaluate the resistance of your materials and systems to all the environmental conditions, including air contaminants, and enable you to make the right choice of materials. We have the equipment and experience to simulate virtually any environment, and our engineering personnel will recommend ways to overcome potential problems stemming from exposure to airborne contaminants. In addition, NTS is a Nationally Recognized Testing Lab (NRTL). Leading telecom manufacturers will only accept results from a NRTL for their systems.

NTS can perform air contaminant testing to various common standards, including IEC (IP), MIL-STD-202, MIL-STD-810, NEMA, GR-63-CORE, and RTCA DO-160 to name a few. Request a quote for our air contaminant testing services today.
