This calculation module applies to instantaneous domestic hot water heat recovery using a counter-flow heat exchanger between the drain water and the incoming domestic cold water. This module calculates the recovered heat, to be taken into account in the overall calculation procedure of the energy performance of the building. The scope of this document is to standardize the: - required inputs; - calculation methods; - required outputs; of the instantaneous heat recovery from domestic hot water drains. This document provides a calculation method for one calculation interval. This calculation is intended to be connected to the whole building calculation model and takes into account the external conditions and system controls that may influence the instantaneous heat recovery from domestic hot water drains. This document does not apply to storage heat recovery or the use of drain water as a source for heat pumps. This document does not apply to sizing or inspection of domestic hot water heat recovery devices. Table 1 shows the relative position of this document within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000-1. NOTE 1 The same Table is found in CEN ISO/TR 52000-2, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation. NOTE 2 The modules represent EPB standards, although one EPB standard might cover more than one module and one module might be covered by more than one EPB standard, for instance a simplified and a detailed method respectively.

This document specifies a test method for the determination of gross beta activity concentration in non-saline waters. The method covers non-volatile radionuclides with maximum beta energies of approximately 0,3 MeV or higher. Measurement of low-energy beta emitters (e.g. 3H, 228Ra, 210Pb, 14C, 35S and 241Pu) and some gaseous or volatile radionuclides (e.g. radon and radioiodine) are not be included in the gross beta quantification using the test method described in this document. This test method is applicable to the analysis of raw and drinking waters with low amounts of total soluble salts in the water. Limit of detection depends on the performance characteristics (background count rate and counting efficiency) of the counter used. It is the laboratory’s responsibility to ensure the suitability of this method for the water samples tested. As this method requires sample preparation in laboratory facilities, it is not suited for rapid, in-the-field analysis.

 

ISO 14001 specifies the requirements for an environmental management system that an organization can use to enhance its environmental performance. ISO 14001 is intended for use by an organization seeking to manage its environmental responsibilities in a systematic manner that contributes to the environmental pillar of sustainability. ISO 14001 helps an organization achieve the intended outcomes of its environmental management system, which provide value for the environment, the organization itself and interested parties. Consistent with the organization's environmental policy, the intended outcomes of an environmental management system include: · enhancement of environmental performance; · fulfilment of compliance obligations; · achievement of environmental objectives. ISO 14001 is applicable to any organization, regardless of size, type and nature, and applies to the environmental aspects of its activities, products and services that the organization determines it can either control or influence considering a life cycle perspective. ISO 14001 does not state specific environmental performance criteria. ISO 14001 can be used in whole or in part to systematically improve environmental management. Claims of conformity to ISO 14001, however, are not acceptable unless all its requirements are incorporated into an organization's environmental management system and fulfilled without exclusion.   Note: This is a consolidated version, which means the amendment will be published as a new version. This approach was chosen to enhance readability and improve the overall user experience.

This International Standard provides general guidance for the design of test rooms intended for the sensory analysis of products. It describes the requirements to set up a test room comprising a testing area, a preparation area, and an office, specifying those that are essential or those that are merely desirable. This International Standard is not specific for any product or test type. NOTE The test space can be similar for food and non-food products that are evaluated using sensory methods. However, the test rooms might need to be adapted for each specialized use. Modifications to the design are often needed for specific products and for specific types of testing. This is particularly true if the test rooms are to be used for the evaluation of non-food products. This standard can be applicable for quality control functions.
