Produktams skirti aplinkosauginiai pranešimai ir jų programos. Aplinkosauginės produktų deklaracijos (ISO/DIS 14025:2025)

1.1 This document specifies principles and requirements, and provides guidance for environmental product declaration (EPD) programmes and their associated environmental product declarations. This document specifies the use of ISO 14040 and ISO 14044 on life cycle assessment in the development of EPDs. 1.2 This document covers EPD programmes and their associated EPDs intended to address environmental impacts and aspects of products which can also include related social and economic aspects in support of sustainable development. NOTE 1 This document does not deal with Social-LCA and Economic-LCA indicators. NOTE 2 Related social and economic aspects of the products can be reported as additional sustainability-related information, where relevant and available. 1.3 This document provides guidance and requirements for the communication of the environmental impacts and aspects of products to the intended audience of the EPD. 1.4 This document does not include sector-specific provisions, which are dealt with in other ISO documents. It is intended that sector-specific provisions in other ISO documents related to EPDs be based on and use the principles, requirements, and guidance of this document.

Vandens kokybė. Augančių mikroorganizmų skaičiavimas. Kolonijų skaičiavimas po sėjimo ant R2A terpės (ISO/DIS 13647:2025)

This document specifies a method for the enumeration of culturable microorganisms in water by counting the colonies on a low-nutrient agar culture medium by spread plate inoculation after incubation at 22 °C for 7 d. The method is intended to measure the operational efficiency of the treatment process of public drinking water supplies, including the water in distribution systems and containers. The method is particularly suitable to monitor water for human consumption which is low in nutrients and is distributed in temperatures below 20 °C (Reference [1]). The method can be applied to all types of water, including pool and spa waters. The low-nutrient agar in use in this document usually gives higher colony counts from water samples than nutrient-rich formulations of culture media typically used for enumeration of culturable microorganisms (References [2], [3], [4]).

Varikliniai pramoniniai krautuvai. Matomumas. Bandymo metodai ir patikra. 11 dalis. Padėklų krautuvai (valdomi vairuotojo)

This document specifies the requirements and test procedures for 360° visibility of self-propelled industrial rider-controlled pallet-stacking trucks in accordance with ISO 5053-1 (herein after referred to as trucks), without a load and it is intended to be used in conjunction with EN 16842-1. This document also applies to pedestrian controlled trucks with foldable platform when used in ride-on mode. Pedestrian-controlled and pedestrian-propelled trucks are not covered by this document. Where specific requirements in this part are modified from the general requirements in EN 16842-1, the requirements of this part are truck specific and intended to be used for self-propelled industrial stand-on pallet-stacking trucks. This part of EN 16842 deals with all significant hazards, hazardous situations or hazardous events relevant to the visibility of the operator for applicable machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.

Iš aplinkos gautos kietosios matricos. Polichlorbifenilų (PCB) nustatymas dujų chromatografija su atrankiuoju masės aptikimu (GC-MS) arba elektronų pagavimo aptikimu (GC-ECD) (ISO 18475:2023)

This document specifies methods for quantitative determination of seven selected polychlorinated biphenyls (PCB28, PCB52, PCB101, PCB118, PCB138, PCB153 and PCB180) in soil, sludge, sediment, treated biowaste, and waste using GC-MS and GC-ECD (see Table 2). The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract. Under the conditions specified in this document, lower limit of application from 1 μg/kg (expressed as dry matter) for soils, sludge and biowaste to 10 μg/kg (expressed as dry matter) for solid waste can be achieved. For some specific samples the limit of 10 μg/kg cannot be reached. Sludge, waste and treated biowaste may differ in properties, as well as in the expected contamination levels of PCB and presence of interfering substances. These differences make it impossible to describe one general procedure. This document contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used. NOTE The analysis of PCB in insulating liquids, petroleum products, used oils and aqueous samples is referred to in EN 61619, EN 12766-1 and EN ISO 6468 respectively. The method can be applied to the analysis of other PCB congeners not specified in the scope, provided suitability is proven by proper in-house validation experiments.
