Maisto grandinės mikrobiologija. Kilpinė izoterminė amplifikacija (LAMP) mikroorganizmams ir susijusiems genetiniams žymenims aptikti. Bendrieji reikalavimai ir apibrėžtys (ISO/DIS 24914:2025)

This standard would provide general requirements and guidance for the development and application of LAMP-based methods for the detection of microorganisms and associated genetic markers sampled along the food chain (e.g., ingredients, human food, animal food, and the production environment), and includes sample preparation, isothermal amplification, signal detection, data interpretation, and performance criteria. This standard would also define laboratory and data management practices to ensure that LAMP methods are performed accurately, and data are reported clearly for end users and stakeholders. Out of scope - LAMP methods applied for non-food (medical/veterinary) use.

Produktams skirti aplinkosauginiai pranešimai ir jų programos. Ekologiniai ženklai (ISO/DIS 14024:2025)

1. This document specifies principles, requirements and gives guidance for ecolabelling programmes and ecolabels. 2. This document covers ecolabelling programme development, selection of product categories, product environmental criteria and product function criteria, and the process for evaluating and certifying products that are licensed to use an ecolabel and provides guidance on how ecolabels in conformity with this document can be differentiated from other ecolabels in the market. NOTE Ecolabels and ecolabelling programmes address environmental aspects of products, but can also include social and economic aspects in support of sustainable development.

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.
