3 Terms and definitions
For the purposes of this European Standard the following definition applies.
3.1
outlet sample
sample drawn from the outlet pump using the normal supply system
4 Sample containers and closures
4.1 Containers
These shall be unused metallic containers of approximately four litres capacity, 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.
NOTE Lead solder may be used for the attachment of external tittings.
4.2 Closures
These shall be able to retain 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 prEN 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 observed 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 clothing suitable to povide 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 atmospheric electrical disturbance or hailstorms.
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 stwcture 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 identity whether they contain petrol or diesel.
5.7 Samples shall be transported in accordance with European ADR regulations (1J, and to any other national or local regulation regarding the transport of flammable products.
NOTE 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 Clause 6)
5.8 Samples shall be stored in accordance with national and local regulations.
NOTE When storing samples that have flash points below ambient temperature consideration should be given to storing
them in a flameproof refrigerator.
6 Sampling procedure
NOTE 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 in 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 filling, sealing and labeling immediately return the filled sample containers to the insulated box and transport them to the laboratory. A suitable insulated box consists of a strong wooden box lined with expanded polystyrene or polyurethane sheeting of approximately 50 mm thickness.
6.1 Using a cotton cloth carefully clean the parts of the delivery pipe nozzle that may come into contact with the sample container and/or the product being sampled.
6.2 Prior to drawing the samples, run at least tour litres of the product through the nozzle into a suitable container.
NOTE This may be either a plastic or metal container approved for use with the product being sampled.
The flushings shall either be removed from the site in the container and disposed olin a sate manner, or returned
to storage on the site.
6.3 Inspect the sample container (see 4.1) for cleanliness and line-up the required number of containers
alongside the fuel dispenser to be sampled.
6.4 Record the reading on the outlet meter display.
6.5 Insert the nozzle of the outlet into the sample container (see NOTE). Activate the filling mechanism and run product into the container in such a way as to prevent splashing, minimise foaming and light end loss and at such a rate to enable air to exhaust from the container without product issuing from the container.
NOTE In order to further minimise light end loss, it is recommended that when taking samples of petrol an extension piece is fitted to the nozzle to enable submerged tilling of the container. A description of suitable nozzle extensions and their use is given in annex A.
6.6 Fill the container with a maximum of three litres of product, using the outlet meter display as a guide.
6.7 Immediately after filling, close the container using an appropriate closure (see 4.2), Check for leaks by inverting the container and holding in an inverted position for 30 s. If a leak is observed replace with a new closure and recheck for leaks. If the leaking continues dispose of the container and its contents in accordance with local regulations. Resample using a new container and closure.
6.8 Clearly label the sample container with the following information.
– Place, date and time of sampling;
– Product and its grade;
– Sample Identification Code.
NOTE This is the minimum information required and other information can also be included as required.
6.9 Seal the sample container in such a manner that the closure and sample label can not be removed without breaking the seal.
6.10 Repeat 6.3 to 6.9 as many times as necessary to comply with any additional national requirements.
6.11 Complete a sampling statement in duplicate.
One copy of the sampling statement shall accompany the analysis sample, the other shall be given to the site representative.
NOTE An example of a suitable sampling statement Is given in annex B.
7 Appointed organisations
7.1 Organisations carrying out the sampling operation shall be accredited with EN 45004 or appointed by a Government Body.
7.2 A list of organisations qualified to draw samples shall be compiled and maintained by the national standardisation body of the member state or its nominated alternate.BS EN 14275 pdf free download.Sampling from retail site pumps and commercial site fuel dispensers
