— Growth promotion. Test each batch of ready-prepared medium and each batch of medium, prepared either from dehydrated medium or from the ingredients described. Inoculate plates of R2A agar separately with a small number (not more than 100 CFU) of the micro-organisms indicated in Table 0008.-1. Incubate under the conditions described in the table. Growth obtained must not differ by a factor greater than 2 from the calculated value for a standardised inoculum. For a freshly prepared inoculum, growth of the micro-organisms must be comparable to that obtained with a previously tested and approved batch of medium. —促生长试验：测试每批已制备好的培养基以及采用脱水培养基制备或按指定的成分制备的培养基。 分别将表0008.-1中指定的不超过100CFU的菌悬液（或孢子悬液）接种在R2A琼脂上，按表中指定的条件进行培养。对于新鲜制备的细菌培养液，微生物的生长必须与先前测试过或者已经认可的培养基具有可比性。
Total organic carbon or oxidisable substances. Carry out the test for total organic carbon (2.2.44) with a limit of 0.5 mg/l or alternatively the following test for oxidisable substances: to 100 ml add 10 ml of dilute sulphuric acid R and 0.1 ml of 0.02 M potassium permanganate and boil for 5 min; the solution remains faintly pink. 总有机碳或易氧化物质：按2.2.44所描述的方法测试总有机碳，限度为0.5 mg/l；或按下述方法测试易氧化物质：取本品100ml，加稀硝酸10ml及0.02M高锰酸钾滴定液0.1ml，煮沸5分钟，溶液仍然显粉红色。
我怎么觉得这个英文的问题很大啊，是缺少内容了吗？ 限度时检测限吗？ the solution remainds faintly pink，这句什么意思？是煮沸前就是粉色，还是煮沸后呈粉色？
Conductivity. Determine the conductivity off-line or in-line under the following conditions. EQUIPMENT Conductivity cell: — electrodes of a suitable material such as stainless steel; — cell constant: the cell constant is generally certified by the supplier and is subsequently verified at suitable intervals using a certified reference solution with a conductivity less than 1500 μS·cm−1 or by comparison with a cell having a certified cell constant; the cell constant is confirmed if the value found is within 2 per cent of the certified value, otherwise re-calibration must be performed. 电导率：按下列条件进行在线或离线电导率测试。 设备：电导池。 一个适当材料（如不锈钢）的电极； 电池常数：电池常数通常被供应商校正，并且以适当的周期使用已经过鉴定的电导率低于1500 μS·cm−1的参照溶液进行确认，或者用一个已经过鉴定的电池常数进行测试比较（标准电极？），如果测得值在给定值的2%以内则此电池常数符合规定，否则应重新校正 这个英文本身比较别扭，翻译出来的中文就有点不顺口。 很可能是因为隔行如隔山，我对这行不懂
Conductometer: accuracy of 0.1 μS·cm−1 or better at the lowest range. System calibration (conductivity cell and conductometer): — against one or more suitable certified reference solutions; — accuracy: within 3 per cent of the measured conductivity plus 0.1 μS·cm−1.
电导率仪：准确度为0.1 μS·cm−1或更低的范围； 系统校正（电导池和电导率仪）： 一个或一个以上的已经过鉴定的参照溶液； 准确度：在被测电导率加0.1 μS·cm−1的3%以内； better at the lowest range 最低范围更好 against这里是什么意思
Conductometer calibration: calibration is carried out for each range of measurement to be used, after disconnection of the conductivity cell, using certified precision resistors or equivalent devices with an uncertainty not greater than 0.1 per cent of the certified value. If in-line conductivity cells cannot be dismantled, system calibration may be performed against a calibrated conductivity-measuring instrument with a conductivity cell placed close to the cell to be calibrated in the water flow.
Temperature measurement : tolerance ± 2 °C. PROCEDURE Measure the conductivity without temperature compensation, recording simultaneously the temperature. Temperature-compensated measurement may be performed after suitable validation. The water to be examined meets the requirements if the measured conductivity at the recorded temperature is not greater than the value in Table 0008.-2.
温度测量：误差± 2 °C 操作程序：在没有温度补偿下测试电导率，同时记录测试温度。在适当的确认之后温度-补偿测量可能被执行。在所记录的温度下测得的电导率不超过表0008.-2中的值则被检测水的电导率符合要求
Temperature-compensated measurement may be performed after suitable validation. 在适当的确认之后温度-补偿测量可能被执行。 这句翻译有点异议 在适当的验证之后可执行温度-补偿测量 主要是这个被动语态在中文感觉不是很常见 然后那个validation是什么操作呢？
