DIN EN 58:2012-05 EN 58:2012 (E) 4 1 Scope This European Standard specif

18、ies methods of sampling bituminous binders, to determine the average quality of the material under examination and/or to determine deviations from average quality. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 composite sample sample made u

19、p by the mixing of several spot samples Note 1 to entry: A composite sample is regarded as a representative sample if the spot samples are taken according to a sampling plan which makes it probable that the composition of the composite sample approaches that of the material as closely as possible. 2

20、.2 divided sample sample formed by dividing a spot, composite or representative sample into several similar parts by appropriate means 2.3 flowing material material which flows in a transport pipeline or out of the drainline of a storage container 2.4 laboratory sample sample intended for laboratory

21、 tests 2.5 layer sample upper, middle or lower layer spot sample taken at a specific depth in a stationary material, usually in order to detect segregation in large storage containers 2.6 main stream sample sample taken from the outlet stream of a container, such that the entire cross-section of the

22、 outlet stream is included 2.7 material under examination entire quantity of the bituminous binder of which the properties are to be assessed Note 1 to entry: “Material under examination“ is termed simply “material“ in the body of this document. 2.8 side-stream sample sample taken from the outlet st

23、ream by means of a sampling probe 2.9 spot sample sample, taken in a single operation at a single place and time Note 1 to entry: If it can be assumed that the material is homogeneous, a spot sample is regarded as a representative sample. If the material is not homogeneous, a spot sample is only reg

24、arded as representative of a limited region around the sampling point. DIN EN 58:2012-05 EN 58:2012 (E) 5 2.10 stationary material material in a storage container when all valves are closed and there is no flowing in the container 2.11 surface sample spot sample taken at less than 5 cm below the upp

25、er surface 2.12 test sample sample produced by treatment or subdivision of a laboratory sample during preparation in the laboratory of the sample for individual tests 2.13 vertical straight-through sample sample taken by drawing a sampling device through the total depth of the material under examina

26、tion and thereby including all layers of the material 3 Safety precautions The safety precautions given in this clause represent good practice and shall be applied in all cases where they are not in conflict with local or other regulations which shall be followed. The list of safety precautions give

27、n in this clause is not necessarily exhaustive and they should be considered in conjunction with relevant national safety regulations and/or recognised safety code(s) for the petroleum industry. a) All regulations concerning entry into hazardous areas shall be observed rigorously. b) Equipment shall

28、 be maintained adequately. Regular inspections of equipment should be carried out by a competent person. c) All equipment and access facilities shall be checked to ensure that they are adequate for safe working before commencement of sampling. d) Metallic sampling devices used in flammable atmospher

29、es shall be constructed only from non-ferrous metal(s). e) Cords used as components of sampling devices shall be constructed only from vegetable fibre(s), e.g. manilla or sisal; for emulsions, the cord used shall not absorb water from the emulsion. NOTE Attention is drawn to the situation that, for

30、cords made from man-made fibres, it is possible for an operator to build up a dangerous level of electrostatic charge on his person, if he is not earthed and wearing insulating gloves, and that certain man-made fibres will melt or dissolve in hot bitumen. f) Precautions shall be taken to prevent the

31、 breathing of bitumen vapours during sampling operations. g) For samples taken from the main stream, the sampling device shall be selected such that sampling can be performed without pressure. 4 Fundamentals of sampling 4.1 Correct sampling techniques are a prerequisite if meaningful test results ar

32、e to be obtained. 4.2 The person taking the sample shall be experienced in the methods to be employed. DIN EN 58:2012-05 EN 58:2012 (E) 6 4.3 If the sample is to be subdivided, a suitably large representative sample shall be taken and divided into the required number of divided samples. 4.4 A sampli

33、ng report shall be prepared and signed by the person taking the sample. The sampling report shall include: a) name and address of the manufacturer, b) name and address of the supplier (if different from manufacturer), c) object of sampling (batch number, storage container, pipe identification), d) n

34、ature and type of material sampled, e) date and time of sampling, f) name of the sampler, g) unique identification of the sample(s), h) number and amount of samples, i) sampling method used, j) reference to this European Standard, k) any deviation, by agreement or otherwise, from the procedure descr

35、ibed in the standard, l) any special observations. A prepared form shall be used for the sampling report (for example, see Annex A); a copy of the sampling report shall be placed with each divided sample. Sampling reports shall not be put into sample containers. Because of the variety of materials f

36、or which the same container vehicle or storage tank may be used, account should always be taken of possible contamination by residues, deposits or solvents. For this reason, it is relevant to enter data in the report on the previous history of the container vehicle or storage tank. 5 Sample size Eac

37、h divided sample should consist of at least 0,5 kg material. NOTE The required size of a laboratory sample is dependent upon the nature and extent of the tests to be carried out. 6 Choice of sampling method The sampling method to be used depends upon: a) nature, quantity and temperature of the mater

38、ial under examination, b) number, type and size of the containers or cans from which the sample is to be taken, c) whether the sample is to be taken from a stationary or a flowing material. Arrangements, equipment and methods of sampling are described in Clause 8. DIN EN 58:2012-05 EN 58:2012 (E) 7

39、If samples shall be taken frequently from a large volume liquid material container, sampling appliances such as sampling valves, sampling probes or three-way cocks can conveniently be installed permanently. Otherwise, liquid test materials shall be sampled by immersion techniques, for example, by we

40、ighted sampling cans or bottom closing sampling tubes; materials fluid at low temperature can be sampled from drums or containers of up to 2 m3capacity by means of open sampling tubes. Table 1 gives an informative guideline for sampling devices. Viscous, plastic and semi-solid material shall be samp

41、led using tools of the kind described in 8.4, semi-solid to brittle material by means of hand-operated tools described in 8.5 and granular material or lumps according to 8.5 and 8.6. Sampling from the main stream by disconnecting the pipe linking a container vehicle to a storage tank shall not be ca

42、rried out.

45、rature - not applicable 7 Number of samples The number of samples taken shall be dependent upon the size and form of the container and for deliveries in cans and lumps upon the number of those in a delivery; the number of samples to be taken from a container shall be as given for each sampling metho

46、d in Clause 8. For deliveries in cans and lumps, the number of cans or lumps from which samples are to be taken shall conform to Table 2. Initially, one sample from each can or lump shall be tested. If this test shows deviation from the specification, the remaining samples shall be tested. DIN EN 58

47、:2012-05 EN 58:2012 (E) 9 If sampling is intended to check homogeneity (segregation) in stationary liquid material, at least three layer samples (upper layer, middle layer and lower layer) shall be taken. They shall not be mixed to form a composite sample. If, in exceptional circumstances, it is des

48、ired to assess the average quality from layer samples, the geometry of the container shall be taken into account.
