BS EN 1014-1:2010EN 1014-1:2010 (E) 4 1 Scope This European Standard specifies procedures for obtaining a representative sample from a consignment of creosote. This standard is only applicable to consignment
19、s of creosote which are in a single phase at the time of the sampling. 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 entire
20、ly liquid before sampling. NOTE 2 All personnel concerned with sampling 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 F
21、or the purposes of this document, the following terms and definitions 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
22、units taken from a larger number of sampling units, or one or more increments 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 S
23、ampling probe consisting of a pipe of about 12 mm bore with a valve, 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
24、 90 and extended for a very short distance, in both cases the orifice 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 a
25、n airtight closure which is resistant to creosote. Rubber closures shall not be used. BS EN 1014-1:2010EN 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 stead
26、y continuous drip such that the sample receiver (3.1.2) shall be 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 thoro
27、ughly. If necessary, heat the contents to ensure that 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 (3.1.3) and close the sample container securely. Mark the sample container to allow identification of the contents
28、. The contents shall constitute the laboratory sample of the consignment 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
29、. 4.1.2 Sample receivers, three glass or metal containers of at 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 t
30、o creosote. Rubber closures shall not be used. 4.2 Procedure 4.2.1 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 tan
31、k contents. 4.2.2 Close the sampling can (4.1.1) and lower it to 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 samp
32、ling can and contents. Allow the creosote on the outside of the 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). BS EN 1014-1:2010EN 1014-1:
33、2010 (E) 6 4.2.3 Repeat the procedure given in 4.2.2 at the 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 an
34、d transfer it to the intermediate sample container (4.1.3). 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 i
35、ntermediate sample container thoroughly. If necessary, heat 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
36、identification of the contents. The contents shall constitute 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 Sa
37、mple receivers, three or more glass or metal containers of 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
38、creosote. Rubber closures shall not be used. 5.2 Procedure 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 t
39、o 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 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
40、 not less than 1 l. NOTE The contents of the intermediate sample 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 fou
41、nd. Sample at these depths, 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 from each of the three sample receivers and transfer it to the i
42、ntermediate 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 volume respectively) and total not less than 1 l. NOTE The contents of the intermediate sample container are considered to be representative of the consi
43、gnment being sampled. BS EN 1014-1:2010EN 1014-1:2010 (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 m
44、m and shall not be less than 80 mm. 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 sample receivers and transfer it to the intermediate sample container (5.1.
45、3). The volumes shall be in proportion to the horizontal 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 pape
46、r the cross-section of the tank, the liquid surface and 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 intermed
47、iate 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 in a single phase. Allowing an ullage space of about 5 % (v/v), pour approximatel
48、y 1 l into the clean dry sample container (5.1.4) 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 consignment being sampled. 6 Sampling report A sampling report shall be written, co
49、ntaining all essential information pertaining to the product sampled and the manner in which the sample was prepared. The report shall at least include the following: a) a reference to this European Standard and, in particular, to those clauses that have been followed; b) unambiguous sample identification marks, such as name and number of the label on the sample container; c) the date of sampling; d) the approximate size of consignment; e) any particular points observed in the course of t
