−20%, or for components with uncritical values such as pull-up resistors. The calculated constant tangential tolerance for this series gives (3 √ 10 − 1) ÷ (3 √ 10 + 1) = 36.60%, approximately. While the standard only specifies a tolerance greater than 20%, other sources indicate 40% or 50%.
Typical F71T12 71-inch, 100-watt, bi-pin tanning lamp. Ultraviolet radiation (UVR) is part of the electromagnetic spectrum, just beyond visible light.Ultraviolet wavelengths are 100 to 400 nanometres (nm, billionths of a metre) and are divided into three bands: A, B and C. UVA wavelengths are the longest, 315 to 400 nm; UVB are 280 to 315 nm, and UVC wavelengths are the shortest, 100 to 280 nm.
