Maisto autentiškumas. Anksčiau užšaldytos paukštienos aptikimo, nustatant HADH aktyvumą, metodas

This document specifies a procedure to determine the HADH activity in poultry meat samples by spectrophotometry. The results can provide an indication whether poultry breast meat has been previously frozen based on the ratio of relative HADH activity, and can be used to verify the labelling of poultry breast meat sold as chilled poultry. A result above a value of 0,5 for the ratio of HADH activity from a sample before and after laboratory freezing, indicates that the sample has been previously frozen. This document is applicable to chicken and turkey breast meat but can be used for other cuts and/or species with appropriate limit values. Additional validation can be required. The document is not applicable to minced meat or to poultry preparations. The compliance assessment process is not part of the document.

Dinaminiai siurbliai be sandariklių. II klasė. Specifikacija (ISO/DIS 15783:2025)

1.1 This International Standard 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. 1.2 Pumps will normally conform to recognized standard specifications (e.g. ISO 5199, explosion protection, electromagnetic compatibility), except where special requirements are specified herein. 1.3 This International Standard 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. 1.4 Where conformity to this International Standard has been requested and calls for a specific design feature, alternative designs may be offered providing that they satisfy the intent of this International Standard and they are described in detail. Pumps which do not conform with all requirements of this International Standard may also be offered providing that the deviations are fully identified and described. Whenever documents include contradictory requirements, they should be applied in the following sequence of priority: a) purchase order (or inquiry, if no order placed), see annexes D and E; b) data sheet (see annex A) or technical sheet or specification; c) this International Standard; d) other standards.

Vandens kokybė. Nurodymai, kaip imti bentosinių stambiųjų bestuburių ėminius iš upėse ir upeliuose esančių buveinių proporcingai pagal jų dydį

This document gives guidance on procedures for the pro-rata multi-habitat sampling of benthic macroinvertebrates in rivers and streams. The term “pro-rata” reflects the intention to sample all the main riverine habitats present at a monitoring site according to the proportion of the site that it covers. It is an objective way to divide sampling effort among the different habitats. This guidance is applicable to all flowing waters, both artificial, modified and natural. This design enables comparable samples to be collected from any type of river, regardless of the habitats present. The pro-rata multi-habitat sampling is an overall approach rather than a specific method. This document is designed to: — support environmental and conservation agencies to meet the monitoring requirements of the WFD (Article 8, Annex II, and Annex V); — generate data sets appropriate for monitoring and reporting of sites designated under the Habitats Directive and the Birds Directive ensure that samples for comparing the overall composition of invertebrates from different stream types are comparable; — ensure samples for environmental quality assessments across different stream types are comparable even when sampled by different people; and — support river management and restoration initiatives. The pro-rata multi-habitat sample (MHS) provides: — a consistent way of sampling sites that is not dependent on the presence of particular types of habitat; and — guidance on a user-friendly strategy for collecting biological data depending on the distribution of substrate type. It is also ideal for: — understanding the distribution of biological community types across different physical river types; and — quality assessments based on deviation from reference, as adopted in the European Water Framework Directive.

NOTE 1 In CEN ISO/TR 52000 2 the same table can be found, 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 may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1. (...)
