This standard is only applicable to consignments of creosote which are in a single phase at the time of the sampling
22、. NOTE 1 At ambient temperature, part of the creosote may be in crystalline form. In such cases, it is necessary to heat the creosote to a temperature above the crystallization point of the particular creosote at which it is entirely liquid before sampling. NOTE 2 All personnel concerned with sampli
23、ng and testing should be fully acquainted with the safety precautions relating to creosote. It is essential that proper safety measures for handling hazardous materials are followed when sampling creosote. 2 Terms and definitions For the purposes of this document, the following terms and definitions
24、 apply. 2.1 consignment quantity of material covered by a particular consignment note or shipping document 2.2 crystallization point temperature at which crystal formation starts in the creosote oil 2.3 sample one or more sampling units taken from a larger number of sampling units, or one or more in
25、crements taken from a sampling unit 2.4 laboratory sample sample as prepared for sending to the laboratory and intended for inspection or testing 3 Sampling flowing creosote from a pipeline by means of a probe 3.1 Apparatus 3.1.1 Sampling probe consisting of a pipe of about 12 mm bore with a valve,
26、fitted into the side of the pipeline on the discharge side of the pump and preferably in a rising section of the pipeline. The pipe extends into the centre of the pipeline, with its inner end bevelled at 45 or its inner end bent at 90 and extended for a very short distance, in both cases the orifice
27、 faces upstream. NOTE A suitable design is illustrated in Figure 1. 3.1.2 Sample receiver, a glass or metal container of at least 5 l capacity. 3.1.3 Sample container, a glass or metal container of approximately 1 l capacity with an airtight closure which is resistant to creosote. Rubber closures sh
28、all not be used. DIN EN 1014-1:2010-11 EN 1014-1:2010 (E) 5 3.2 Procedure 3.2.1 Place the clean, dry sample receiver (3.1.2) under the exit of the sampling probe (3.1.1). Adjust the valve on the sampling probe (3.1.1) to produce a steady continuous drip such that the sample receiver (3.1.2) shall be
29、 filled in the time required to pump the entire consignment being sampled past the sampling probe. NOTE This sample is considered to be representative of the consignment being sampled. 3.2.2 Mix the contents of the sample receiver thoroughly. If necessary, heat the contents to ensure that they are i
30、n a single phase. Allowing an ullage space of about 5 % (v/v) pour approximately 1 l into the clean, dry sample container (3.1.3) and close the sample container securely. Mark the sample container to allow identification of the contents. The contents shall constitute the laboratory sample of the con
31、signment being sampled. 4 Sampling from a tank having a uniform horizontal cross section throughout its depth 4.1 Apparatus 4.1.1 Weighted metal sampling can of at least 550 ml capacity. NOTE A suitable design is illustrated in Figure 2. 4.1.2 Sample receivers, three glass or metal containers of at
32、least 1 l capacity. 4.1.3 Intermediate sample container, a glass or metal container of at least 5 l capacity. 4.1.4 Sample container, a glass or metal container of approximately 1 l capacity with an airtight closure which is resistant to creosote. Rubber closures shall not be used. 4.2 Procedure 4.2
33、.1 A sample shall be taken at each of the following positions in the tank, using the procedure given in 4.2.2: the middle of the upper third of the tank contents; the middle of the tank contents; the middle of the lower third of the tank contents. 4.2.2 Close the sampling can (4.1.1) and lower it to
34、 the required depth in the tank and open it. NOTE If a sampling can of the type illustrated in Figure 2 is used, the can is opened by jerking the chain sharply to remove the conical cap. When air bubbles cease to rise, lift out the sampling can and contents. Allow the creosote on the outside of the
35、sampling can to drain off and then pour off carefully and reject about 50 ml of the contents. Measure out a known volume, at least 500 ml, of the contents of the sampling can into the sample receiver (4.1.2). DIN EN 1014-1:2010-11 EN 1014-1:2010 (E) 6 4.2.3 Repeat the procedure given in 4.2.2 at the
36、 other two sampling points. Each sample shall be placed in its own sample receiver (4.1.2) and mixed well. If necessary heat the contents to ensure that they are in a single phase. Withdraw a volume from each of the three sample receivers and transfer it to the intermediate sample container (4.1.3).
37、 The volumes shall be the same within 5 % of their mean and total not less than 1 l. NOTE The contents of the intermediate sample container are considered to be representative of the consignment being sampled. 4.2.4 Mix the contents of the intermediate sample container thoroughly. If necessary, heat
38、 the contents to ensure they are in a single phase. Allowing an ullage space of about 5 % (v/v), pour approximately 1 l into the clean, dry sample container (4.1.4) and close the sample container securely. Mark the sample container to allow identification of the contents. The contents shall constitu
39、te the laboratory sample of the consignment being sampled. 5 Sampling from a horizontal cylindrical tank 5.1 Apparatus 5.1.1 Weighted metal sampling can of at least 550 ml capacity. NOTE A suitable design is illustrated in Figure 2. 5.1.2 Sample receivers, three or more glass or metal containers of
40、at least 1 l capacity. 5.1.3 Intermediate sample container, a glass or metal container of at least 5 l capacity. 5.1.4 Sample container, a glass or metal container of approximately 1 l capacity with an airtight closure which is resistant to creosote. Rubber closures shall not be used. 5.2 Procedure
41、5.2.1 If the tank is full, sample at standard depths of 1/6, 1/2 and 5/6 of the total depth, using the procedure given in 4.2.2. Each sample shall be placed in its own sample receiver (5.1.2) and mixed well. If necessary, heat the contents to ensure that they are in a single phase. Withdraw a volume
42、 from each of the three sample receivers and transfer it to the intermediate sample container (5.1.3). The volumes shall be in the ratio of 3:4:3 by volume (for the samples taken at 1/6, 1/2 and 5/6 of the total depth respectively) and total not less than 1 l. NOTE The contents of the intermediate s
43、ample container are considered to be representative of the consignment being sampled. 5.2.2 If the tank is not full and tank calibration tables are available, ascertain the depths above which 1/6, 1/2 and 5/6 of the total volume is to be found. Sample at these depths, using the procedure given in 4.
44、2.2. Each sample shall be placed in its own sample receiver (5.1.2) and mixed well. If necessary, heat the contents to ensure that they are in a single phase. Withdraw a volume from each of the three sample receivers and transfer it to the intermediate sample container (5.1.3). The volumes shall be
45、in the ratio of 3:4:3 by volume (for the samples taken at 1/6, 1/2 and 5/6 of the total volume respectively) and total not less than 1 l. NOTE The contents of the intermediate sample container are considered to be representative of the consignment being sampled. DIN EN 1014-1:2010-11 EN 1014-1:2010
46、(E) 7 5.2.3 If the tank is not full and calibration tables are not available, take samples at evenly spaced intervals commencing at the surface of the creosote, using the procedure described in 4.2.2. The intervals shall not be greater than 300 mm and shall not be less than 80 mm. Each sample shall
47、be placed in its own sample receiver (5.1.2) and mixed well. If necessary, heat the contents to ensure that they are in a single phase. Withdraw a volume from each of the sample receivers and transfer it to the intermediate sample container (5.1.3). The volumes shall be in proportion to the horizont
48、al volume interval of the tank about the point at which the sample was taken and total not less than 1 l. These proportions may readily be obtained by first determining the position of the liquid surface in the tank, then plotting on squared paper the cross-section of the tank, the liquid surface an
49、d drawing horizontal lines representing the boundaries of each layer to be sampled. Counting the squares in each area representing a layer of creosote gives the proportions in which the samples shall be combined. NOTE The contents of the intermediate sample container are considered to be representative of the consignment being sampled. 5.2.4 Mix the contents of the intermediate sample container thoroughly. If necessary heat the contents to ensure that they are
