(1) EN 1991-1-6 provides principles and general rules for the determination of actions which should be taken into
The available standard regulates requirements and examinations for gasfilters up to a nominal size of including DN 250, which operat with gases of DVGW-Arbeitsblatt G 260 (without LPG at liquid phase) at a maximum working pressure of 5 bar.
This European Standard establishes the baseline requirements for performing and documenting FAI. Should there be a conflict between the requirements of this European Standard and applicable statutory or regulatory requirements, the applicable statutory or regulatory requirements shall take precedence. The primary purpose of FAI is to validate that product realization processes are capable of producing parts and assemblies that meet engineering and design requirements. A well-planned and executed FAI will provide objective evidence the manufacturer's processes can produce compliant product and that they have understood and incorporated associated requirements. FAI will: - Provide confidence that the product realization processes are capable of producing conforming product. - Demonstrate that the manufacturers and processors of the product have an understanding of the associated requirements. - Provide objective evidence of process capability. - Reduce potential risks associated with production start-up and/or process changes. - Provide assurance of product conformance at the start of production and after changes outlined in this European Standard. An FAI is intended to: - Reduce future escapes, risks, and total costs. - Help ensure safety of flight. - Improve quality, delivery, and customer satisfaction. - Reduce costs and production delays associated with product nonconformances. - Identify product realization processes that are not capable of producing conforming product, and initiate and/or validate corrective actions. This European Standard applies to organizations that are responsible for producing the design characteristics of the product (i.e., product realization). The organization shall flow down the requirements of this European Standard to suppliers or processors who produce design characteristics. This European Standard applies to assemblies, sub-assemblies, and detail parts including castings, forgings, and modifications to standard catalogue or Commerci
Mould spores and metabolites can be inhaled via the air and cause allergic and irritating reactions and/or complex symptoms in humans. Increased concentrations of these compounds are considered a potential health risk. Moreover, mould growth may be associated with severe odour nuisances. This part of EN ISO 16000 provides assistance for the sampling strategy for suitable sampling and analysis methods together with a description of the applicability and the interpretation of the measurement results to maximize the comparability of the measured data obtained for a given measurement objective. Details on field inspections by qualified professionals which have to take place prior to any microbiological measurement are described. Depending on the analysis method mould spores are determined individually or as spore aggregate. Materials, indoor air and house dust will not only contain culturable but also non-culturable mould spores, some of which may have the same allergenic and toxic effects as culturable spores. For this reason, techniques have been developed which allow the microscopic determination of both culturable and non-culturable moulds. The sampling methods employed for detection of moulds are determined by the objective of the investigation (DIN ISO 16000-16 \"Filtration\" or DIN ISO 16000-18 \"Impaction\"). Depending on the sampling method, the moulds will suffer a sampling stress during sample collection and preparation, which may lead to their drying-out or dying. Mould detection and differentiation are performed either after cultivation based on morphological criteria, biochemical reactions and/or molecular techniques or by direct microscopic examination (DIN ISO 16000-17).
This part of ISO 16000 specifies the planning of carbon dioxide indoor pollution measurements. In the case of indoor air measurements, the careful planning of sampling and the entire measurement strategy are of particular significance since the result of the measurement may have far-reaching consequences, for example, with regard to ascertaining the need for remedial action or the success of such an action. An inappropriate measurement strategy may lead to misrepresentation of the true conditions or, worse, to erroneous results. This part of ISO 16000 is intended to be a link between Part 1 of ISO 16000, \"General Aspects of Sampling Strategy\", and the analytical procedures. Before indoor air measurements are carried out, the purpose of the measurement shall be clearly defined. In the case of determination of carbon dioxide, the following objectives are chiefly of interest and are dealt with in detail: - Investigating compliance with a guide value - Investigating the ventilation situation in a room By means of the measured value the ventilation rate needed can be used as a criterion of good air quality indoors and for calculating the design of room conditioning systems for ventilating indoor areas. Examples for calculations are presented.
This part of ISO 16000 specifies the requirements for investigating buildings for the presence of pollutants or other harmful factors, as basis for a subsequent sampling of suspect areas and determining the quantity and type of pollutant, which are described in other parts of ISO 16000. The results of the investigation provide the basis for assessing the building with regard to utilisation, remediation or demolition. An assessment with regard to utilisation may include hygiene and comfort parameters (e. g. for \"Building Passports\"). In specific circumstances it may be expedient to to assess the indoor air quality in order to undertake an investigation. The following objectives can be achieved: - to provide instructions for a structured approach, - to gather data and information as the basis for a more detailed assessment, - to assist in the compilation of a pollutant register, - to provide legal certainty for the client and the provider.
