| Title | Characterization of sludges - Determination of calorific value |
| Work Item Number | 00308038 |
| Abstract/Scope | This European Standard specifies a method for the determination of the gross calorific value of sludge at constant volume and at the reference temperature 25 °C in a bomb calorimeter calibrated by combustion of certified benzoic acid. The result obtained is the gross calorific value of the sample at constant volume with both the water of the combustion products and the moisture of the sludge as liquid water. In practice, sludges are burned at constant (atmospheric) pressure and the water is not condensed but is removed as vapour with the flue gases. Under these conditions, the operative heat of combustion to be used is the net calorific value of the fuel at constant pressure. In this European Standard the net calorific value at constant volume is described as it requires less additional determinations. This method is applicable to all kinds of sludges. |

In the case of undated standard, a link to the last dated version is provided.
In the case of series, a link to each standard identified in the series is provided.
We also invite you to check (via the website) whether corrigenda and/or amendments shall be read in conjunction with the main standard.
(7) This list of bibliographic references, which is provided for homegrown standards only, is purely indicative and was retrieved automatically using available XML files. It is limited to publications that have been published in the XML format. For standards that are not homegrown, the corresponding international standard should be consulted.
