3 Terms and definitions
For the purposes of this document, the following term and definition applies.
outlet sample
sample drawn from the dispensing pump using the normal pump nozzle
4 Sample containers and closures
4.1 Containers
These shall be unused, preferably metallic, containers of the required capacity for execution of the intended testing program, constructed from lead-free material, with packing glands or welded joints, able to withstand normal internal pressures encountered during normal operations. The containers shall be equipped with an external fitting to enable them to be sealed. The container shall not have been treated with a petroleum-based rust-preventative.
Certain test methods, especially for trace element analysis, require specific sampling equipment and containers made with material known not to interfere with the analysis.
Lead sokler may be used for the attachment of external fittings.
4.2 Closures
These aim at retaining the integrity of the sample. Insert disks may additionally be used to close the container outlet. Suitable closures include screw caps fitted with a washer resistant to the product being sampled. Cork or rubber washers shall not be used.
5.1 The following minimum safety requirements shall be read in conjunction with the requirements for safety as given in EN ISO 3170 and, in addition, any national or local safety, environmental and transportation regulations.
5.2 Personnel drawing the samples shall be made aware of the potential hazards and be given instructions in safety precautions to be obsen,ed as set out in the Materials Safety Data Sheet.
5.3 Care shall be taken to avoid breathing petroleum vapours during the sampling. Protective gloves of hydrocarbon-insoluble materials, eye protection and dothing suitable to provide protection against all known hazards associated with the product shall be worn.
5.4 In order to avoid static electricity risks, special precautions shall be taken during the sampling operation.
5.4.1 Sampling shall not be carried out during periods of atmospheflc electrical disturbance or halistorms.
5.4.2 Foot wear and/or clothing capable of causing sparks shall not be worn In areas where flammable vapours are likely to be present.
5.4.3 In order to earth any static charge on their person, the person taking the samples shall touch some part of the fuel dispensing structure immediately before carrying out any sampling operation.
5.5 Samples shall not be taken during the supplying of the tank to which the pump to be sampled is connected.
5.6 Samples shall be clearly labelled to Identify whether they contain petrol or diesel.
5.7 Samples shall be transported in accordance with European ADR regulations [1]. and to any other national or local regulation regarding the transport of flammable products.
When transporting samples of petrol it is recommended that they be placed in an insulated box containing a cooling medium such as solid carbon dioxide or ice. (See NOTE in 6.1.)
5.8 Samples shall be stored In accordance with national and local regulations.
When storing samples that have flash points below ambient temperature consideration should be given to storing them in a flameproof refrigerator.
6 Sampling procedure
6.1 In order to minimise loss of light ends when sampling petrol, the following procedure is recommended. Cool the sample containers in a refrigerator and place them En an insulated box containing a cooling medium such as solid carbon dioxide or ice. Transport them to the sampling site in the insulated box. After fIlhng, sealing and labelling immediately return the filled sample containers to the insulated box and transport them to the laboratory.
NOTE A suitable insulated box consists of a strong wooden box lined with expanded polystyrene or polyurethane sheeting of approximately 50 mmttiickness.BS/EN 14275-2013 pdf download.
