主题：【求助】有哪个做过EN14372的邻苯测试？

看了下EN14372的6.3.2测试邻苯，好像和一般的索氏提取很不一样，哪个真正按标准做过？到底怎么做啊。有没有EN14372的作业指导书啊？
Place the sample in a pre-weighed 150 ml flat bottomed flask and heat in an oven at (105 ± 5) °C for (30 ± 5) min.
Allow to cool in a desiccator. Weigh the flask and sample. Use a scalpel or other appropriate cutting utensils to cut
a representative portion from the sample into small pieces (< 5 mm ∅). Weigh accurately (2 ± 0,2) g of the pieces
into a Soxhlet thimble and add cotton wool to the top of the thimble.
Add approximately (50 ± 10) ml of diethyl ether into the flask. Reflux gently for 6 h ± 30 min. Allow sufficient time for
the diethyl ether to cool. Completely evaporate the diethyl ether by means of a steam bath. Place the flask in an
oven at (105 ± 5) °C for (30 ± 5) min. Allow to cool in a desiccator and weigh. Repeat the drying and cooling cycles
until the difference between two consecutive weighings are not more than 0,0005 g. A blank solution shall be run
consecutively.
