At the first meeting of TC 19 in January 1963, it was recognized that, for certain commonly used tests on petroleum products, the national standards organizations in many of the CEN countries had adopted (with or without minor modifications) the standard methods published by the American Society for Testing and Materials (ASTM). It was accordingly decided that a CEN Unification document for sampling bituminous materials should be based upon the ASTM method D 140. A first draft document N 147 was circulated in February 1969 and was approved, no comments having been received, by the fourth CEN/TC 19 meeting in April 1969 for submission to the CEN Central Secretariat as a draft Unification Document. The results of the CEN Member Body ballot were reviewed by the fifth TC 19 meeting held in Stockholm in September 1971 and it was decided to defer work on the production of a Unification Document and to commence a study of the draft German Standard DIN 52 001 as an alternative basis to ASTM D 140 for a European Standard. A first draft proposal (N 331) was circulated in September 1973 and the comments received, which were entirely of an editorial character, have been incorporated in the draft which was approved for submission to the CEN Secretariat as a draft European Standard by the seventh meeting of TC 19 which was held in The Hague in November 1973. The comments were incorporated in the final text which in 1983 was submitted to the CEN secretariat by the Nederlands Normalisatie-instituut who had assumed the secretariat of CEN/TC 19 in 1981. The member countries of CEN which approved this European Standard are the following: Denmark, Finland, France, Germany, Italy, Portugal, United Kingdom. The following member countries disapproved this European standard: Austria, Belgium. Amendment 1:1986 This Amendment 1 to the European Standard EN 58 was drawn up by the Technical Committee CEN/TC 19 “Test methods and specifications for petroleum products”, the Secretariat of which is held by NNI. This Amendment was adopted by CEN on the strength of its acceptance by the following Member countries: Denmark, Finland, France, Germany, Italy, Portugal, Spain, United Kingdom.

The methods are not applicable to samples of manufactured bituminous materials containing significant quantities of mineral matter, e.g. mastic asphalts, tar macadams or hot rolled asphalts. These materials require techniques significantly different from those specified in this standard. Samples may be taken, either to establish the average quality of the material under examination, or to determine deviations from its average quality. The latter samples shall be expressly marked as being for this purpose. 2 Definitions For the purpose of this European Standard the following definitions apply: 2.1 material under examination the whole quantity of the bituminous material the properties of which are to be assessed 2.2 stationary material material in a container in which there is no flow, i.e. the valves of the container are closed and the container is not in motion 2.3 flowing material a liquid material which is in the process of being transferred 2.4 spot sample a sample, taken in a single operation at a single place and time of the material being sampled. If it can be assumed that the material is homogeneous, a spot sample can be regarded as an average sample. If the material is not homogeneous, a spot sample only can be regarded as representative of a limited region around the sampling point 2.5 composite sample a sample made up by mixing several spot samples. A composite sample can be regarded as an average sample, if the spot samples are taken according to a plan which makes it probable that the composition of the composite sample approaches that of the material under examination as closely as possible 2.6 divided sample a sample formed by dividing a spot, composite or average sample into several similar parts by appropriate means 2.7 laboratory sample a sample intended for laboratory tests. It may be a spot sample, a composite sample or a part thereof (a divided sample) 2.8 test sample a sample produced by treatment or subdivision of a laboratory sample during laboratory preparation of the sample for individual laboratory tests 2.9 referee sample a spot or a composite sample which, as a whole or after subdivision, serves for arbitration tests 2.10 layer sample (e.g. upper, middle and lower layer samples) spot samples (see 2.4) which are taken from various heights in a stationary liquid, usually in order to detect segregation in large storage containers 2.11 surface sample a spot sample taken from within 5 cm of the upper surface 2.12 straight-through sample a total depth sample, taken by drawing a sampling appliance through the total depth of the material under examination, and therefore including all the layers of the material. If a straight-through sample includes all layers of the material volume proportionally, it can be regarded as an average sample 2.13 main stream sample a sample taken from the outlet stream from a container, such that the whole cross-section of the outlet stream is included 2.14 side-stream sample a sample taken from the main stream by means of a sampling probe Licensed Copy: sheffieldun sheffieldun, na, Wed Nov 29 07:36:46 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 58 4 © BSI 07-1999 3 Safety precautions 3.1 The safety precautions given below apply in all cases and constitute good practice, but the list is not necessarily comprehensive. It is recommended that the list should be read in conjunction with the appropriate national safety regulations or any recognized code in the petroleum industry. The precautions given below shall be taken whenever they do not conflict with local or other regulations which shall, in any case, always be followed: a) all regulations covering entry into hazardous areas shall be rigorously observed; b) plant and equipment shall be adequately maintained, and it is recommended that a regular inspection should be made by a competent person. 3.2 Before commencing the collection of samples, check all the equipment and access facilities to ensure that they are adequate for safe working. 3.3 If metal sampling gear is used in flammable atmospheres, it shall be constructed of non-ferrous metal. Attention is also drawn to the fact that when using man-made fibre cords such as nylon, it is possible for the operator to build up a dangerous electrostatic charge on his person if he is not earthed and wearing plastics gloves. Cords made of vegetable fibre, for example manilla or sisal shall therefore be used in such cases. 3.4 Care shall be taken to avoid breathing petroleum vapour during sampling operations. 4 Fundamentals of sampling Correct sampling techniques are a prerequisite if meaningful test results are to be obtained. 4.1 The person taking the sample shall be informed of the purpose of sampling and shall be competent in those methods described herein which it is intended to employ. 4.2 If the sample is required for use by more than one party, a suitably large sample shall be taken, homogenized if necessary, and divided into the required number of samples. 4.3 A report shall be prepared and signed by the person taking the sample and by any other authorized agent of any other party present. The report shall note the reasons for and methods of sampling, the surrounding circumstances and the required tests. A special form shall be used for this report (for model form, see Annex A). A copy of the report shall be made available for each divided sample. The reports shall not be put into sample containers. NOTEBecause of the variety of bituminous materials for which the same container vehicle or the same storage tank may be successively used, account should always be taken of possible contamination of the container by residues, deposits or solvents. For this reason it is convenient to enter relevant data in the report on the previous history of the container. 5 Sample size The required size of a laboratory sample is dependent upon the nature and extent of the tests to be carried out. Each divided sample shall consist of at least 2 kg, or in the case of emulsions, at least 3 kg. 6 Choice of sampling method The sampling method to be used depends on: a) the tests to be carried out; b) the purpose of the tests; c) the nature, quantity and temperature of the material under examination; d) the number, type and size of the containers or cans from which the sample is to be taken; e) whether the sample is to be taken from a stationary or a flowing material. Permitted arrangements, equipment and methods of sampling are described in clause 8. If samples have to be taken frequently from a large volume liquid material container, sampling appliances such as sampling valves, sampling probes or threeway cocks can conveniently be installed permanently. Otherwise liquid test materials shall be sampled by immersion techniques, for example, by weighted sampling cans or bottom closing sampling tubes; materials fluid at low temperature can be sampled from drums or co
