Where the goods are found to be in retail packaging, you should always take whole retail packages as your sample. You may take more than one package if this is necessary to reach the minimum sample size.Where the goods are found to be articles (e.g. timber, metal castings or sheets) you should generally take whole items.However, for goods that are in bulk or in wholesale packages you will usually need to take smaller samples. It is important that you use the correct type of storage container for the goods.Sample containers: general information and requirementsThe type of container you should use for storing and transporting the samples is determined by the physical and chemical properties of the goods and the storage and transport requirements.The container used for packing samples taken must meet the following requirements:it must not be affected by the sample (especially important for samples of chemical substances, petroleum products, solvents, foodstuffs — which may be acidic, etc.);it must ensure that the quality (integrity) of samples is maintained;it must be designed and manufactured in a way that allows leak-proof or air-tight closure;it must be strong enough to withstand transport and storage;it must be designed to ensure proper sealing and preclude unauthorised handling.In choosing sampling containers you must follow the principles listed in Table 1.The stoppers and caps used for closing the sample holders (bottles/containers) must ensure a tight seal to prevent any leakage or evaporation of the samples. The material of which the containers and stoppers are made must not be susceptible to chemical attack by the samples and must not interact with or contaminate them.Depending on the nature of samples taken crown caps, plastic or metal screw caps additionally reinforced to ensure better sealing can be used. The use of cork and rubber plugs should be avoided.The most commonly used sample containers are plastic or metal containers, glass bottles, metal canisters and plastic bags or boxes (see Table 2). The design of sample containers may vary in different Member States. The list of sample containers is therefore not exhaustive and other types of packages may be used provided they meet all the requirements.Table 1Type of goodsRequirements for the packageGoods to be examined for humidity and fat contentPackaging must not absorb moisture or fat.Perishable, frozen, and cooled goodsPackaging must not be affected by low temperature.Goods containing volatile componentsStopper or cap must allow air-tight closure.Liquid goods, prone to fermentationPackaging must be closed with a screw-type stopper or cap.Samples of fruit juices or juices of plant origin must be frozen immediately and kept frozen until analysed.All other fermentable liquids must be mixed with 2 g of salicylic acid per 1 litre of sample, or another fermentation-slowing agent at an appropriate concentration.Table 2Type of GoodsPackaging RecommendationPetroleum Products - liquid fuels, lubricantsMetal containersGlass bottlesPolypropylene (PP) bottlesPolyethylenterephtalate (PET) bottlesOrganic solventsMetal containersGlass bottlesPolypropylene (PP) bottlesPolyethylenterephtalate (PET) bottlesLiquid vegetable oils and fatsMetal containersGlass bottlesGlass jarsPolypropylene (PP) bottlesPolyethylenterephtalate (PET) bottlesVarious types of chemical substancesMetal containersGlass bottlesPolypropylene (PP) bottlesPolyethylenterephtalate (PET) bottlesFood productsPaper bagsPolyethylene (PE) and polypropylene (PP) bags, bottles, etc.Glass jarsSpirits and ethyl alcoholGlass bottlesPolypropylene (PP) bottlesPolyethylenterephtalate (PET) bottlesList of Sample ContainersCodeContainer TypeSuitable forP00 Plastic bagsDifferent sizesWith or without pre-printed label Goods taken in form of pieces such as tiles, wood, paper, textiles, metal sheets, various articles, etc.goods in their retails sale packagestobaccodried fruitfloursandsugarstarchP01 Plastic bottleNarrow openingNormal size100 ml to 500 mlLeak-proof closure Non-volatile liquids, such as:petroleum products such as kerosene, gas oil, heating oil, lubricants etc. with exception of gasolinefatty acids methylesters (FAME) and mixtures of FAME with mineral oilsvegetable oilsjuices and syrupsnon-alcoholic beveragessurface active agents and preparationsnon-volatile chemicals and chemical preparationP02 Plastic bottleNarrow openingNormal size50 ml to 100 mlLeak-proof closure High-value goods, such as:fragment of precious metalsdiamondspure chemicalsspicesmetal chips or fragmentsP03 Plastic bottleWide mouth openingNormal size100 ml to 500 mlLeak-proof closure Powdered and granulated materials or pastes, such as:lubricating greasesVaselinesandsugarstarchinstant beveragesteasolidified vegetable oils and fatstobaccoP04 Plastic bottleWide mouth openingNormal size500 ml to 1000 mlLeak-proof closure Dried fruit, powdered materials and pastes, such as:flourpaints and varnishesP05 Plastic bottleSmall size50 ml to 100 mlAir-tight closure High-value volatile liquids, such as:foodstuffs aromaticsfoodstuff supplementsfragrances, cosmetics, essences etc.light-sensitive materials (stored in dark containers)P06 Plastic bottleSmall size100 ml to 500 mlAir-tight closure Liquids, such as:spirit and alcoholic beveragesdenatured spiritantifreeze solutionssoap and cleaning solutionsorganic solvents and thinnersP07 Plastic bottleNormal size500 ml to 1000 mlAir-tight closure Liquid foodstuffs, such as:winebeerlow-alcohol beverages and solutionsR00 Paper bagsDifferent sizesWith or without pre-printed label TobaccoPlantsGoods taken in form of pieces, such as: tiles, wood, paper, textiles, metal sheets and articles.R01 Cardboard boxes, cartonsDifferent sizesWith or without pre-printed label TobaccoPlantsGoods taken in form of pieces, such as: tiles, wood, paper, textiles, metal sheets and articles.G01 Glass bottleLarge size500 ml to 1000 mlLeak-proof closure Special liquids, such as:white spiritgasolinespirit and alcoholic beverageslight sensitive samples (e.g. olive oil)organic solvents and thinnerslight sensitive liquids (stored in dark receptacles)M01 Metal canLarge size500 ml to 1000 mlLeak-proof closure Special liquids, such as:white spiritgasolinespirit and alcoholic beveragesorganic solvents and thinnerslight sensitive liquids (e.g vegetable oils)M02 Metal bottleLarge size500 ml to 1000 mlNarrow openingLeak-proof closure Special liquids, such as:white spiritgasolinespirit and alcoholic beveragesorganic solvents and thinnersDo not use for acidic or basic liquids, such as vinegar or brine!M10 Metal gas cylinderMedium size Gases and liquefied gasesBack to top
