1、 ERRATA NFPA 2001Standard on Clean Agent Fire Extinguishing Systems 2015 Edition Reference: Various Errata No: 2001-15-1 The Committee on Gaseous Fire Extinguishing Systems notes the following errors in the 2015 edition of NFPA 2001, Standard on Clean Agent Fire Extinguishing Systems. 1. Replace Fig
2、ure A.5.5.3.2(f) with the correct figure shown below (this was a production error). FIGURE A.5.5.3.2(f) Distribution Curve No. 5. 2. Insert the missing equation for C.2.8.1.3 (production error); and correct the numerator in the equation (editorial error) to read as follows: C.2.8.1.3 Leak Fraction f
3、or Lower Leakage Method. If a lower leaks test is performed and the lower leakage is measured, then the lower leak fraction (F) is determined using the following equation: C.2.8.1.3 For extinguishants lighter than air, F = 0.5. 3. Remove the first equation (it does not belong) for C.2.8.1.5.3 (produ
4、ction error) and insert the correct equation instead, to read as follows: C.2.8.1.5.3 Calculation for Extinguishants That Are Lighter Than Air. C.2.8.1.5.3 Calculate mf using Equation C.2.7.1.4 and substituting Cmin for Ci. 4. Insert the missing equation for C.2.8.2 (production error) to read as fol
5、lows: C.2.8.2 Leakage area for visualization or relief vent calculation is found by the following equation: C.2.8.2 This leakage area is commonly referred to as the equivalent leakage area (EqLA) and is equivalent to the area of a hole in a thin flat plate with a discharge coefficient of 0.61 at the
