This document specifies a method for the determination of selected polybrominated diphenylethers (PBDE) (see Figure 1 and Table 1) in sediment, suspended particulate matter and biota using gas chromatography coupled with tandem mass spectrometry (GC-MS/MS) or with high resolution mass spectrometry (GC-HRMS) in the electron impact (EI), negative ion chemical ionization (NCI) or atmospheric pressure ionization (APCI) mode. The method is applicable to sediment and suspended particulate matter samples with limits of quantification of 0,2 µg/kg dry mass (dm) for brominated diphenylether (BDE) BDE-28 to BDE-183, of 2 µg/kg dry mass (dm) for BDE‑209. The method is applicable as well with lower limits of quantification (LOQ), if specific clean-up methods, described in Clause 10, Table 3, method 1 and method 2 in combination with measurement methods GC-MS/MS or GC-HRMS after electron impact ionization (El) or negative ion chemical ionization (NCI) for BDE-209 are used. Depending on the analytical capability of the instrument, limits of quantification down to 0,003 µg/kg dm for BDE-28 to BDE-154 and 0,02 µg/kg dm for BDE-183 and 1 µg/kg dm for BDE-209 and lower are possible. The method is applicable to biota samples with limits of quantification down to 0,000 2 µg/kg fresh mass (fm) (BDE-28 to BDE-154) and 0,03 μg/kg fresh mass (fm) (BDE-183), if specific clean-up methods, described in Table 4 in combination with measurement methods GC-MS/MS or GC-HRMS after electron impact ionization (El) are used.

This document describes the test and assessment procedure for determining the contribution of reactive fire protection systems to the fire resistance of solid steel bars used as tension members, when exposed to the standard temperature/time curve specified in EN 1363-1. In special circumstances, where specified in National Building Regulations, there can be a need to subject reactive fire protection systems to a slow heating curve (smouldering fire) as defined in EN 1363-2. The corresponding test and assessment procedure are described in Annex E. The fire protection performance is determined by testing mechanically loaded steel bars in horizontal orientation. Information regarding the testing of additional unloaded specimens is given to assess the influence of the bar orientation and smouldering fire behaviour.
The principles of the testing and assessment procedure can also be applied for other section shapes such as angles, channels and flats. This document does not include steel bars used as reinforcement in concrete construction.
The document is applicable to steel bars up to a maximum diameter of 130 mm. In the case of rectangular bars, the maximum edge length shall be limited to 130 mm with a maximum aspect ratio of 2:1 against the shorter edge length.
The test programme and the assessment are designed to cover:
-   a range of valid fire protection classification periods;
-   a range of thickness of the applied reactive fire protection system;
-   a range of steel bar dimensions and profiles;
-   a range of specified design temperatures;
-   a range of load utilisation factors in case of fire;
-   a range of bar orientation.
This document also provides the assessment procedure, which prescribes how the analysis of the test data shall be made and gives guidance on the procedures by which interpolation shall be undertaken. The assessment procedure is used to establish:
a)   on the basis of data derived from mechanically loaded testing steel bar, any practical constraints on the use of the reactive fire protection system under fire test conditions (the physical performance);
b)   on the basis of the temperature data derived from testing steel bar the thermal properties of the reactive fire protection system (the thermal performance).
The limits of applicability of the results of the assessment arising from the fire test are defined together with permitted direct application of the results to different steel types and sizes over the range of thicknesses of the applied reactive fire protection system tested.

This document specifies the requirements for seal-less rotodynamic pumps that are driven with permanent magnet coupling (magnet drive pumps) or with canned motor, and which are mainly used in chemical processes, water treatment and petrochemical industries. Their use can be dictated by space, noise, environment or safety regulations. Seal-less pumps are pumps where an inner rotor is completely contained in a pressure vessel holding the pumped fluid. The pressure vessel or primary containment device is sealed by static seals such as gaskets or O-rings. Pumps normally conform to recognized standard specifications (e.g. ISO 5199, explosion protection, electromagnetic compatibility), except where special requirements are specified herein. This document includes design features concerned with installation, maintenance and operational safety of the pumps, and defines those items to be agreed upon between the purchaser and manufacturer/supplier. Where conformity to this document has been requested and calls for a specific design feature, alternative designs can be offered providing that they satisfy the intent of this document and they are described in detail. Pumps which do not conform with all requirements of this document can also be offered providing that the deviations are fully identified and described. Whenever documents include contradictory requirements, they are applied in the following sequence of priority: purchase order (or inquiry, if no order placed), see Annexes C and D; data sheet (see Annex A) or technical sheet or specification; this document; other standards.
