Definicija

(popis oznaka HS koje obuhvaća ova kartica)		 Proizvodi od voska koji su vrlo viskozne paste ili krutine, kao što su vazelin, parafinski vosak, mikrokristalni naftni vosak, pčelinji vosak ili bitumen.

Pasty products such as casein, gelatin and dextrins are also covered in this card.

Waxy products in the form of (fine) powder, see specific card ‘Chemicals, solid’.

Liquid waxes, see specific cards ‘Petroleum liquids’ and ‘Chemicals, liquids’.

For products in retail sale packages see specific card ‘Retail packages and finished articles’.


Vosak
Preporučena minimalna količina za svaki uzorak 0,25 kg
Primjenjive norme (ISO i norme EU-a) i relevantno zakonodavstvo

 Treba se također služiti i svojim nacionalnim zakonodavstvom i nacionalnim smjernicama o uzorkovanju.

Potrebna oprema
Predloženi alat za uzorkovanje, ovisno o primijenjenoj metodi
  • Klipna štrcaljka (L05-01)
  • Svrdlo za uzorkovanje (S04-01)
  • Ručna bušilica (E02-01)
  • General tools: knife, (metal) spatula
  • Sampling scoop (L04-01)
  • Sampler for frozen goods (E01-01)
  • Pipeline sampler (L06-01)
Posude koje se upotrebljavaju pri uzorkovanju
  • Metalne posude (M01)
  • Staklene boce (G01)
  • Plastične boce (P03 ili P04)
Sigurnosne mjere opreza i procjena rizika Dodatne informacije potražite u svojem nacionalnom zakonodavstvu i smjernicama o zaštiti zdravlja i sigurnosti. See SDS if available.

  • Nosite zaštitne rukavice i zaštitne naočale.
  • U normalnim uvjetima vosak ne predstavlja posebnu opasnost za zdravlje, osim kada je zagrijan. Voskovi koji su na okolnim temperaturama u krutom stanju mogu se prevoziti pri povišenim temperaturama (izbjegavajte temperature od 50 do 70 °C) kako bi se olakšalo punjenje ili pražnjenje cisterni. There is a risk of skin burns and eye damage if boiling spray comes into contact with the mucous membranes or the eyes.
  • If splashed with hot product, wash immediately with abundant cold water to relieve the burning and obtain medical assistance immediately.
  • Ne pokušavajte ukloniti vrući proizvod s kože ili skinuti odjeću zalijepljenu proizvodom za kožu.
  • Zapaljivi materijal niskog rizika. Proizvod može formirati zapaljive smjese i zapaliti se samo ako se zagrije iznad svojeg plamišta. Međutim, rizik se može povećati zbog prisutnosti manjih količina hlapljivijih ugljikovodika.

Plan uzorkovanja
Vrsta pošiljke Postupak
Consignment for customs clearance The aggregate sample consists of an appropriate number of incremental samples. When you are satisfied the consignment is homogeneous, one incremental sample is usually taken as representing the goods covered by the same customs declaration.

Pobrinite se da proizvod koji se uzorkuje ostane nepromijenjen u postupku uzorkovanja. NEMOJTE ponovno zagrijavati uzorke jer bi to moglo ugroziti svojstva uzorka – prouzročiti gubitak hlapljivih elemenata ili fizikalnu/kemijsku promjenu zbog pregrijavanja.

Bulk products - loose in tank, tanker truck, reservoir wagon, drums, tank cars — heated Form one aggregate sample from three or more incremental samples, taken from at least three heights: approximately 15 % from the bottom, half-way up and approximately 15 % from the top surface of the product in each lot. Check the homogeneity of the lot — if the homogeneity is in doubt, take more incremental samples.

Where the product is heated above 40 degrees, consider whether the consignment should be treated as dangerous goods and the sampling to be carried out by specially trained officers or a contractor. You should only proceed if you are satisfied that you have appropriate PPE and sampling equipment and can carry out the sampling safely.

Warning: do not allow the product to cool in the tank or drums because it may be extremely difficult do remove the product if it solidifies.

Bulk products - loose in tank, tank truck, reservoir wagon, drums, tank cars — not heated (ambient temperature) Take one aggregate sample. If the product is in the form of a creamy paste or hard paste, take a number of incremental samples, dependent on the homogeneity in each lot. Check the homogeneity of the lot — if the homogeneity is in doubt, take more incremental samples. Different products or lots have to be sampled separately.

  • Products in highly viscous liquid state: before sampling, draw off an appropriate quantity of product, to prime the sampling circuit and valve. If the container has been unused for a long time, it is good practice to re-circulate the product before taking samples.

  • Products in solid state: do not heat the product and use a hand drill sampler (E02-01) or a sampler for frozen goods (E01-01).

  • Products in the form of a creamy paste: do not heat the product and use a spiral sampler (S04-01) or sampling scoop (L04-01) to take several samples at various positions and depths in the mass, to ensure that the sample is as representative as possible. After taking the samples from the mass, prepare the composite sample in a metal bucket by mixing vigorously with the metal spatula and transfer the samples in appropriate containers.

    • If the product is in the form of a hard paste, use a spiral sampler S04-01 to take several samples at various positions and depths in the mass, to ensure that the sample is as representative as possible. After taking the samples from the mass, prepare the composite sample in an appropriate bucket by breaking up and mixing the cores of product with the metal spatula and transfer the samples in appropriate containers.
Barrels, crates, small containers — heated/not heated Take one aggregate sample. Equal quantities of incremental samples are taken from different transport containers found at different positions in the transport vehicle or in the storage facility by random selection or systematically. Check the homogeneity of the lot — if the homogeneity is in doubt, take more incremental samples. Different products or lots must be sampled separately.

Bulk being moved with a conveyor or other flowing product during filling or emptying Take one aggregate sample from incremental samples, taken across the whole diameter of the stream, at intervals determined by the moving speed during filling or emptying of a tank, tanker truck or reservoir wagon. Use a pipeline sampler L06-01. Connect the filling/emptying pipe with a sampling accessory, consisting of a tap (whether or not heated), which draws incremental samples from the centre of the flow. Several samples should be taken at regular intervals throughout the transfer process. After taking the samples, quickly prepare the aggregate sample in an appropriate metal bucket by mixing vigorously and transfer the samples in appropriate containers.


Rukovanje uzorcima
Opće napomene
  • In principle the minimum quantity of identical final samples, required by the laboratory according to your national guidelines, should be enough, providing you are satisfied the product is homogenous.
  • When possible, take a sample directly into the sample bottle. This reduces the possibility of air absorption, loss of vapours, and contamination.
  • If a mixing vessel is used, all incremental samples from all sampling spots are collected and after they have been thoroughly mixed, an aggregate sample is created.
  • The sample bottle should be filled leaving a small space for expansion due to heat. Samples where the moisture content may affect the analysis must be packed in moisture-tight containers with an airtight closure and must be filled completely.
  • After obtaining the sample, close the bottle immediately with a tight-fitting stopper and check the tightness (leakage test).
  • The sample should be handled and packaged in a well-ventilated place or outdoors.
  • Sampling of heated liquids: The containers are left to cool down before closing. Do NOT re-heat samples as this may affect the properties of the sample — loss of volatile elements or physical/chemical change due to over-heating.
Obrazac za uzorkovanje
  • Popunite obrazac za uzorkovanje. Jedan primjerak prilaže se uzorcima, a jedan se ostavlja u evidenciji. Mention if the sample was taken under heated conditions.
Prijevoz
  • Preferably at ambient temperature. Prema potrebi, držite rashlađeno u skladu s oznakama na proizvodu (kazein, dekstrini, modificirani škrobovi itd.).
Skladištenje
  • Preferably at ambient temperature. Prema potrebi, držite rashlađeno u skladu s oznakama na proizvodu (kazein, dekstrini, modificirani škrobovi itd.). Ako je rashlađeno radi skladištenja, potrebno je pratiti i evidentirati temperaturu.
