All testing is performed on standard dust collection units. Even so, the re- sults can also apply to containment systems because a contained dust col- lector uses the same cleaning system as a conventional collector. Compliance is voluntary Complying with Standard 199 is volun- tary, and it's up to each dust collector and filter supplier to develop a compli- ance plan. Smaller suppliers may find the costs involved with developing an in-house test lab and commissioning independent testing prohibitive. Pho- to 1 shows the test rig installed at our company's in-house lab. Another factor that could influence how and when the standard is fol- lowed within industry is the potential involvement of the International Or- ganization for Standardization (ISO), which is considering whether to adopt it. If ISO does, more equipment sup- pliers and customers worldwide are likely to implement it. Questions to ask potential dust collec- tor and filter suppliers Since participation in Standard 199 testing is voluntary, ask the dust col- lection suppliers you're considering where they stand on the standard and request their Standard 199 test reports. If a supplier doesn't offer the test data, it will limit your ability to make educated decisions. The more customers ask suppliers for test data, the more the market will move toward widespread adoption of the standard. Here are other questions to consider asking. The responses should help you evaluate potential suppliers: Does your company operate an in- house lab to conduct Standard 199 testing? A supplier who has installed an in- house Standard 199 test rig demon- strates a strong commitment to the program. In addition, the lab helps the supplier improve its collector de- signs and, more importantly, enables the supplier to test filter elements in equipment built by the manufacturers under evaluation. The test is the most accurate gauge of real-world perfor- mance. Note: This specialized data is not available from independent lab tests, where the same dust collector rig is used for all Standard 199 data. Has your company commissioned independent testing? Even if in-house test facilities are avail- able, a conscientious supplier will also commission independent testing and offer third-party verification of filter performance. Independently certified results are important and should be used in conjunction with the equip- ment manufacturer's in-house testing. Are the filter elements that your staff specified for my application the same as those that were tested under Standard 199?
