24、6811-1:2016 (E) 5 Introduction De-icing agents are important for the winter maintenance of roads. They can prevent and, in addition to it, eliminate slippery conditions. The standard describes the requirements for de-icing salt and their testing methods. The requirements are different for using, sto
25、rage and type of distribution (spreading and spraying). These need different properties. The aim of this standard is an easy description of the product specifications for tenders and other purchasing procedures. BS EN 16811-1:2016EN 16811-1:2016 (E) 6 1 Scope This European Standard specifies the ess
26、ential requirements of sodium chloride (salt) for spreading on roads for winter maintenance and includes tests of these requirements. The requirements are specified for salt in crystallized form and for salt in solution (brine), which is delivered to the customer. 2 Normative references The followin

34、For the purposes of this document, the terms and definitions given in EN 15144 and the following apply. 3.1 sodium chloride salt NaCl, substance which is produced as rock salt, as solar salt and as vacuum salt Note 1 to entry: Rock salt is extracted by mechanical mining of natural salt beds. Solar s
35、alt is produced by solar evaporation of sea water or brine from salt deposits and by extraction from salt lakes. Solar salt from sea water is named as sea salt. Vacuum salt is prepared by the evaporation of water from brine. Used salt (waste salt) comes from secondary aluminium smelters, from fisher
36、y industry, from leather industry, etc. REACH 4 registered synthetic by-product salts derive from chemical reactions (e.g. from gas cleaning in waste incinerators). 3.2 brine solution of sodium chloride in water Note 1 to entry: Brine is available as natural brine from underground deposits and from
37、solar salt/sea salt production, and as solution of rock salt, solar salt/sea salt or vacuum salt in water. Further sources are used salts and by-product salts. 4 Requirements for sodium chloride 4.1 Chemical Requirements The sodium chloride shall conform to the requirements specified in Table 1: Tab
38、le 1 Chemical requirements for sodium chloride Parameter Limit Weight % NaCl min. 90aSulfate max. 3aNOTE 1 NaCl is determined as total chloride content and expressed as NaCl (weight % in the dry product). NOTE 2 Sulfate is determined as water soluble sulfate and expressed as SO4(weight % in the dry
39、product). aThe NaCI and sulfate content of salt can be specified within these limits by the purchaser depending on his individual needs. It can also be specified within these limits at the national level (National Annexes to this European Standard). 4.2 Moisture The sodium chloride shall conform to
40、the requirements specified in Table 2. BS EN 16811-1:2016EN 16811-1:2016 (E) 8 Table 2 Moisture limits for sodium chloride Limit Weight % Dry salt Semi-dry salt Wet salt Moisture max. 0,6 max. 2,0 max. 6,0 For storage in silos dry salt is recommended. For rock salt a minimum moisture content of 0,2
41、weight % is recommended (to avoid dust during stocking and salt usage). NOTE 1 For undried vacuum salt the limit is max. 3,5 weight %. NOTE 2 The moisture contents are expressed as H2O in the delivered undried salts. 4.3 Sieve analysis The sodium chloride shall conform to the requirements specified
42、in Table 3. Table 3 Sieve analysis for sodium chloride Weight % passing test sieve Grade EF (extra fine salt) Grade F (fine salt) Grade M (medium salt) Grade C (coarse salt) 0,125 mm max. 5 0,8 mm 25 to 100 2,0 mm 100 (2 weight % production related tolerance with max. 3 mm grain size) 0,125 mm max.
