This document is applicable to iron (III) sulfate solid used for treatment of water intended for human consumption. It describes the characteristics of iron (III) sulfate solid and specifies the requirements and the corresponding analytical methods for iron (III) sulfate solid and gives information on its use in water treatment. It also determines the rules relating to safe handling and use of iron (III) sulfate solid.

This document specifies requirements and gives reference to the test methods defined for fire dampers, which are intended to be installed in general Heating and Ventilating (HVAC) installations in buildings. All fire dampers close automatically in response to raised temperatures indicating fire. This document gives details for the provision of evaluation of conformity and marking of fire dampers.Fire dampers meeting the requirements of this document may be considered suitable for both ducted and non-ducted applications.This document applies to fire dampers with a declared specific fire resistance (Mandate M/117) that are to be used in conjunction with partitions to maintain fire compartments.This document is not applicable to fire dampers that may be used in applications where the presence of process chemicals may affect fire damper performances.This document is not applicable to non-mechanical fire barriers nor to air transfer grilles.To avoid duplication, reference is made to a variety of other standards. To this end, it is advised to read this document in conjunction with EN 1366-2 for details of the fire resistance testing and EN 13501-3 for classification.

This document specifies fire testing requirements for water mist systems used for fire protection of combustion turbines in enclosures with volumes exceeding 260 m³.

This European Standard specifies two methods for digestion of soil, treated biowaste, sludge and waste by the use of aqua regia as digestion solution.This European Standard is applicable for the following elements: aluminium (Al), antimony (Sb), arsenic (As), barium (Ba), beryllium (Be), bismuth (Bi), boron (B), cadmium (Cd), calcium (Ca), cerium (Ce), cesium (Cs), chromium (Cr), cobalt (Co), copper (Cu), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), gallium (Ga), germanium (Ge), gold (Au), hafnium (Hf), holmium (Ho), indium (In), iridium (Ir), iron (Fe), lanthanum (La), lead (Pb), lithium (Li), lutetium (Lu), magnesium (Mg), manganese (Mn), mercury (Hg), molybdenum (Mo), neodymium (Nd), nickel (Ni), palladium (Pd), phosphorus (P), platinum (Pt), potassium (K), praseodymium (Pr), rubidium (Rb), rhenium (Re), rhodium (Rh), ruthenium (Ru), samarium (Sm), scandium (Sc), selenium (Se), silicon (Si), silver (Ag), sodium (Na), strontium (Sr), sulfur (S), tellurium (Te), terbium (Tb), thallium (Tl), thorium (Th), thulium (Tm), tin (Sn), titanium (Ti), tungsten (W), uranium (U), vanadium (V), ytterbium (Yb), yttrium (Y), zinc (Zn), and zirconium (Zr).This European Standard may also be applicable for the digestion of other elements.Digestion with aqua regia will not necessarily accomplish total decomposition of the sample. The extracted analyte concentrations may not necessarily reflect the total content in the sample.
