WebThe most commonly used rating is the Beta Ratio, which is defined as the ratio of the number of particles upstream of the test filter versus the number downstream, greater than a given size. Using the Beta Ratio, a 5 micron … WebTo remove confusion, manufacturers should describe the performance of the media used inside a filter by its 'beta ratio'. ISO 16889 (International Standard) lists eight common Beta ratios used to report filter efficiency: Beta 2, 10, 20, 75, 100, 200, 1000 and 2000. So what does each one mean and why have so many? WebHere’s an example: If a 5-micron filter element has 1,000,000 particles upstream (pre-filtration) and allows 1,000 particles downstream (post-filtration), it’s Beta ratio would be calculated as 1,000,000 (upstream) / … iowa department of public health marijuana

WebThe efficiency of the filter can be calculated directly from the Beta Ratio since the % efficiency is simply (beta-1)/beta x 100. A Beta 1000, 5-micron filter is thus said to be 99.99% efficient at removing 5 micron and larger particles. Webμ = E [ x] The mean is also called the first moment of x about the origin. The covariance that describes of the uncertainty of x is defined by expectation ( E) as: P = E [ ( x − μ) ( x − μ) T] The covariance is also called the second moment of x about its mean. If the dimension of x is one, P is only a scalar.
