3.1 Replace the definition 3.1 by: 3.1 dilution medium liquid or solid used for the preparation of control vessels and the preparation of test mixtures
3.8 Replace the definition 3.8 by: 3.8 liquid sludge sludge that has the characteristic of a liquid as specified in the definition of a liquid waste (3.9)
5 Taking of laboratory sample Replace the NOTE by: NOTE Sampling devices are described in a Technical Report under development (prCEN/TR 15310-2).
6 Transport Replace the last sentence by: A transport time of less than 48 h and/or a low temperature conditions (4 ± 2) °C are appropriate to maintain the properties of laboratory samples.
7.2 Waste sample Replace second paragraph by: A storage time of less than two months and low temperature conditions (4 ± 2) °C are appropriate to maintain the properties of waste samples.

11.2.1 Leaching procedure Replace the third paragraph by : Ecotoxicological tests usually require several litres of eluate leading to an adjustment of mass of the test portion. When a large volume of eluate is required, it is possible to perform the leaching test in a vessel of appropriate capacity into which the corresponding number of test portions [a dry mass of (90 ± 5) g] are introduced or to perform parallel leaching tests at the same time with an appropriate number of vessels of 1 l capacity each (see above). In that case, all the individual eluates shall be mixed in order to obtain the test sample. When the leaching test is performed in one vessel, the size of the vessel shall be appropriate to minimise the headspace (≤ 5 % of the total capacity of the vessel).
