It is important to regularly evaluate LEV Testing Frequency. Although an essential function of the HP lewes test methodology, determining the ideal LEV Testing frequency is not straightforward in many cases. Many times system owners are surprised to find that their test results vary greatly from the specified frequency. In most cases, the real issue is not the deviation from the ideal frequency but rather the deviation from the closest possible value.
The ideal frequency for measuring the total pollutant release rate (TTR) is one of the more complex concepts in the world of design and analysis. Based on the fact that HP processes continuously throughout any operating environment, the TTR measurement must be done after hours, in the presence of background air, at ambient temperature, and with as little wear and tear as possible. This is why, when performing the Lev test, a thorough examination of the machine's emissions as well as its surroundings is a crucial part of the process. It is also why, when selecting the LEV Testing, a careful consideration of the test data is absolutely necessary. In essence, there are three different types of tests performed, the first two being the "real world" and "environments" tests. Depending on the specific requirements of each particular job, these three tests will differ in their approach.
The first point of comparison between the two is the "daylight" times contact test, which compares the number of times contact is made between a random selection of member posts and the exhaust vents. As the name would suggest, this test is performed on an hourly basis, once every hour, during daylight hours. Because this is a thorough test, it is performed before any other stringent test, such as a carbon monoxide detection test. The "daylight" times contact test should always be performed when it is feasible, since a missed detection could result in costly and time-consuming repairs.
The second of the Virtual Environment frequency test measurements the extent of the damage to the member posts, or the "lewes." If a member post has sustained significant damage, as measured through the photographic evidence, a more detailed analysis of the damage will need to be performed. For example, if one of the members had sustained puncture damage that had resulted from a hammer blow during the installation process, then the damage would most likely be greater than those experienced by other members, and thus, a more thorough analysis of the lewes would be required.
The third of the tests measuring the amount of heat produced during the test is called the "flash furnace." As the name implies, it measures the temperature rise inside a container holding one of the member posts during the entire duration of the flash furnace test. During the flash furnace test, the temperature of the container is increased until the flash furnace begins to go out. It is not uncommon for this portion of the testing frequency to be conducted in an area with access restrictions. Once the temperature begins to return to normal, it is time to perform another Leviton LEV test.
The fourth of the four tests measuring equipment performance is called the "feed-in-tar" test, and is conducted at the end of the day's testing. This portion of the testing frequency involves the use of a special container containing pigments. The container is placed inside a small metal box, and the pigment in the container is fed into the testing machine in small doses. A reader known as a "feed-in meter" is used in order to record the results, and a technician interprets the data. The testing frequency is usually varied according to the level of accuracy and precision of the feed-in meter. Find out more about synergy at https://en.wikipedia.org/wiki/Synergy.
