This document specifies a method for the determination of total dissolved solids (TDS) in water and eluates, provided they are not volatile under the conditions specified or that they do not release water molecules from hydration. It applies to water and eluates containing more than 100 mg/l of total dissolved solids. Samples with lower amounts of dissolved solids can be analysed by repetition of the drying step.

This document specifies two methods for digestion of soil, treated biowaste, sludge and waste by the use of aqua regia as digestion solution.

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 but represent the aqua regia soluble metals under the condition of this test procedure. It is generally agreed that for environmental analysis purposes, the results are fit for the intended purpose to protect the environment.

This document is applicable for the following elements:

Aluminium (Al), antimony (Sb), arsenic (As), barium (Ba), beryllium (Be), boron (B), cadmium (Cd), calcium (Ca), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), magnesium (Mg), manganese (Mn), mercury (Hg), molybdenum (Mo), nickel (Ni), phosphorus (P), potassium (K), selenium (Se), silver (Ag), sodium (Na), strontium (Sr), sulfur (S), tellurium (Te), thallium (Tl), tin (Sn), titanium (Ti), , vanadium (V), and zinc (Zn),.

This document can also be applied for the digestion of other elements, provided the user has verified the applicability.

prEN 14972-1,2): Fixed firefighting systems — Water mist systems — Design, installation, inspection and maintenance

This document specifies the assembly of components to produce a pump set which meet the performance requirements and characteristics for specified water supplies in accordance with the design, assembly, installation and commissioning of the main fire diesel and electric pump sets used in fixed firefighting systems conforming to EN 12845, CEN/TS 14816 and EN 16925.

This document is also applicable to fire-fighting pump sets for firefighting hydrants and hose reels where included in the fixed firefighting water supply specification.

This part of the ISO 14644 standards gives guidance on the interpretation and application of the results of the measurement of Particle Deposition Rate (PDR) on one, or more vulnerable surfaces in a cleanroom as part of a contamination control programme. It provides some guidance on how to influence the PDR and reduce the risk of particle contamination on vulnerable surfaces.

This standard gives information on how a cleanroom user can use the PDR measurements to determine limits that can be set for macroparticles on vulnerable surfaces. It also gives a risk assessment method by which an acceptable risk of deposition of particles onto vulnerable surfaces in a cleanroom can be established and, when this is not achieved, methods that can be used to reduce the PDR.

Note to entry: An alternative to the PDR is the particle obscuration rate which determines the rate of increase of coverage of particles onto an area of surface over time. The POR can be used in an analogous way to the PDR and the required POR for a specified surface can be calculated and the risk from deposited particles reduced.

This standard does not:

• provide a method to classify a cleanroom with respect to PDR or POR,

• directly consider the deposition of microbe-carrying particles (MCPs), although MCPs can be treated as particles,

• give any consideration to surface deposition by contact as, for example, when personnel touch a product and contamination is transferred.

This document establishes the minimum requirements applicable to the design, installation, functioning, test and maintenance of fixed automatic fire extinguishing systems for kitchen protection that covers the kitchen appliances, the hood, the plenum and the exhaust ducts.

This document also provides requirements for the construction and components performance as applicable to specific types, designs, sizes and arrangements of pre-engineered kitchen fire-extinguishing systems.

This document does not cover household kitchens or industrial food production equipment.

This part of ISO 16000 specifies a laboratory test method using test chambers defined in ISO 16000-9 and further specified in EN 16516 and evaluation procedures for the determination of odours emitted from building products and materials.

Sampling, transport and storage of materials under test, as well as preparation of test specimens are described in ISO 16000-11 and further specified in EN 16516.
