This document specifies the minimum requirements for monitoring, receiving and processing of alarm messages generated by alarm systems taking place as a part of the total fire, safety and security solution.
For the purpose of this document, the term “alarm” is used in the broad sense to include fault, status and other messages received from one or more of a range of safety and security alarm systems such as but not limited to fire detection and fire alarm systems, fixed firefighting systems, intrusion and hold-up alarm systems, access control systems, video surveillance systems, social alarms systems and combinations of such systems.
This document gives requirements for two categories of ARC, category I and category II. A category I ARC will be designed, constructed and operated to a higher standard with respect to construction, security and integrity than a category II ARC.
The categorization is determined according to the type(s) of alarm messages handled.
Category I: ARCs handling messages from security applications:

- I; &HAS’s;
- access control systems;
- VSS in security applications that require an emergency response (for example loss prevention);
- people monitoring, lone workers and object tracking systems for security applications;
- alarm messages handled by category II ARCs;
- combinations of the above systems.

Category II: ARC’s handling messages from non-security applications:

- fire alarm systems;
- fixed firefighting systems;
- social alarm systems;
- audio/video door entry systems;
- VSS in non-security applications (for example traffic flow);
- people monitoring, lone workers and object tracking systems for non-security applications;
- lifts emergency systems;
- combinations of the above systems.

The requirements apply to ARC’s (whether established in single or multiple sites) monitoring and processing alarms generated by systems installed at other locations and also to ARC’s monitoring solely alarms from systems within their own site.
The document includes functional and specific requirements supporting the services of an ARC.
The document does NOT apply to:

This document specifies a method for the determination of the estrogenic potential of water and waste water by means of a reporter gene assay with genetically modified yeast strains Saccharomyces cerevisiae. This reporter gene assay is based on the activation of the human estrogen receptor alpha.
This method is applicable to:
—          fresh water;
—          waste water;
—          aqueous extracts and leachates;
—          eluates of sediments (fresh water);
—          pore water;
—          aqueous solutions of single substances or of chemical mixtures;
—          drinking water.
The limit of quantification (LOQ) of this method for the direct analysis of water samples is between 8 ng/l and 15 ng/l 17β-estradiol equivalents (EEQ) based on the results of the international interlaboratory trial (see Annex F). The upper threshold of the dynamic range for this test is between 120 ng/l and 160 ng/l 17β-estradiol equivalents (EEQ). Samples showing estrogenic potencies above this threshold have to be diluted for a valid quantification. Extraction and pre-concentration of water samples can prove necessary, if their estrogenic potential is below the given LOQ.

This document specifies a method for the determination of certain cyclic volatile methylsiloxanes (cVMS) in environmental water samples with low density polyethylene (LDPE) as a preservative and subsequent liquid-liquid extraction with hexane containing 13C-labeled cVMS as internal standards. The extract is then analysed by gas chromatography-mass spectrometry (GC-MS).
NOTE       Using the 13C-labeled, chemically identical substances as internal standards with the same properties as the corresponding analytes, minimizes possible substance-specific discrimination in calibrations. Since these substances are least soluble in water, they are introduced via the extraction solvent hexane into the system.

This European Standard describes a standard method for determining the PM10 or PM2,5 mass concentrations of suspendedparticulate matter in ambient air by sampling the particulate matter on filters and weighing them by means of a balance.
Measurements are performed with samplers with inlet designs as specified in Annex A, operating at a nominal flow rate of 2,3 m3/h,over a nominal sampling period of 24 h. Measurement results are expressed in μg/m3, where the volume of air is the volume atambient conditions near the inlet at the time of sampling.
The range of application of this European Standard is for 24 h measurements from approximately 1 μg/m3 (i.e. the limit of detection ofthe standard measurement method expressed as its uncertainty) up to 150 μg/m3 for PM10 and 120 μg/m3 for PM2,5.
This European Standard describes procedures and gives requirements for the testing and use of so-called sequential samplers,equipped with a filter changer, suitable for extended stand-alone operation. Sequential samplers are commonly used throughout theEuropean Union for the measurement of concentrations in ambient air of PM10 or PM2,5. However, this European Standard does notexclude the use of single-filter samplers.
This European Standard represents an evolution of earlier European Standards (EN 12341:1998 and 2014, EN 14907:2005). Newequipment procured shall comply fully with this European Standard.
Older versions of these samplers, including those described in EN 12341:2014 Annex B, have a special status in terms of their use. These samplers can still be used for monitoring purposes and for ongoing quality control, provided that a well justified additionalallowance is made to their uncertainties
This European Standard also provides guidance for the selection and testing of filters with the aim of reducing the measurementuncertainty of the results obtained when applying this European Standard.
