EMI Site Surveys, On-Site Testing and In-Situ Testing
Keystone Compliance has established a strong reputation of being an industry leader in Electromagnetic Compatibility testing (EMC testing). Our testing expertise includes EMC testing both in one of our many EMC test chambers or outside of our lab. Our field testing includes EMI site surveys, EMC on-site testing and EMC in-situ testing.
EMI and EMC Site Surveys for Implantable Devices:
An Electromagnetic Interference site survey (EMI site survey) is an independent assessment of potential EMI risks. These risks might interfere with an implantable electrical device such as a pacemaker or defibrillator. The assessment should be completed by a qualified and accredited independent test lab such as Keystone Compliance and in collaboration with the employer, manufacturer of the device, patient and physician.
A site survey is conducted by taking various electromagnetic measurements throughout the facility. Keystone Compliance uses a broad range of industry-accepted standards and specifications to determine which electromagnetic fields exist. Following completion of the on-site survey, Keystone Compliance provides the customers with a detailed site survey report. This report identifies EMI sources and zones that have the potential to interact with an implantable electrical device. This information should then be shared with the physician and employer. Collectively, an action plan should be developed to reduce potential negative effects to the patient’s health.
It is important to note that Keystone Compliance is one of just a handful of labs in the country certified by implantable device manufacturers to complete EMC site survey testing.
General EMI and EMC Site Surveys:
An EMI site survey provides the electromagnetic environment of a facility. Essentially, a site survey determines the electromagnetic waves and radio frequency (RF) that are active in a location. Keystone Compliance is able to determine the frequencies and levels of RF and EMI at a location.
Facilities that frequently require site survey testing include military installations, hospitals, schools, factories and offices. Even some homeowners seek EMI site surveys. There are several purposes for a site survey. Security is a growing concern, especially in the interest of data protection and electromagnetic pulse (EMP testing) protection. Health and safety are two other motivating factors. Another catalyst for completing a site survey is faulty equipment that is being impacted by RF.
A growing site survey need is shielding effectiveness. An increasing number of facilities are looking to expand their ability to block RF. The threats of EMP attacks is growing. Keystone Compliance works with the military, utilities, defense contractors and hospitals. Their objective is often to determine the effectiveness of buildings and rooms to block electromagnetic signals. We have significant experience providing testing for this purpose.
Upon completion of the site survey, we provide a comprehensive test report. This report provides information on the levels and amounts by location.
EMI On-Site Testing and IN-Situ Testing:
Not every piece of equipment is mobile or can fit in an EMC test chamber. When circumstances do not permit chamber testing, EMC is able to complete EMC on-site testing for this equipment. On-site EMC testing is often referred to as in-situ EMC testing.
Testing on-site can take a number of different paths. The testing can occur in an isolated location, where ambient signals are minimized. If that is not a possibility, the EMC compliance testing can occur right on the factory floor or in the fixed location of the equipment. The testing can include immunity and emissions testing.
The immunity and emissions testing are completely automated. They follow the same test procedures as if the testing were occurring in the EMC chamber. Ambient signals are identified and considered when assessing the performance of the device being tested.
Some of the more common site survey test scopes include conducted emissions, EMF and microwave field surveys. We also provide power quality, radiated magnetic field, stray current and surveillance testing as well.
Expert EMI Site Survey Compliance Testing
Just as the case with in lab testing, our on-site testing is customer-focused. There is communication throughout the entire test program. We complete the testing expeditiously and provide a thorough test report. We are ISO-17025 accredited and our test reports are recognized around the world.
Our EMC engineers are very experienced at problem resolution. They offer engineering guidance that helps overcome obstacles that might arise. Our equipment is portable and can accommodate tight spaces. With a large staff and redundant equipment, we can move quickly. Leads times on scheduling are short. We can also assist in developing a test plan as well. Our EMC site survey expertise can identify the areas to most focus on. Our on-site testing of equipment is streamlined. We do not over-test. Nor do we allow ambient signals to cloud the test results.
