Tests were performed at BAM unless otherwise stated in the name of the experiment; ‘rep’ stands for repeated experiments. The temperature was 20°C ±2°C in all experiments.
^a‘Duration of storage’ refers to treated test specimens. SD, standard deviation (mg/m²); ‘control’, experiment with untreated wood; OECD 313, test specimens (1.5 × 2.5 × 5 cm³); OECD 313^a, test specimen as in TS-2 (2.5 × 5 × 15 cm³).
