Dirvožemio gerinimo medžiagos ir auginimo terpės. Ėminių ėmimo ir ruošimo metodai

This document specifies references to methods for sampling of soil improvers and growing media and sample preparation of soil improvers and growing media for subsequent determination of quality and quantity. This document is applicable to the fertilizing product blends where a blend is a mix of two or more fertilising products belonging to the categories of fertilizers, liming material, soil improvers, growing media, inhibitors and plant biostimulants, and where soil improvers and/or growing media are the components with the highest percentage in the blend by mass or volume, or in the case of products in liquid form by dry mass. If the soil improvers and/or growing media are not the components with the highest percentage in the blend, the European Standard relevant to the component with the highest percentage in the blend applies. In case a blend is composed of fertilising products mixed in equal quantities, the user of the standard decides which standard to apply. NOTE A soil improver or a growing medium consists of a single bulky (volume-building) component or a mix of bulky (volume-building) components (for example peat, wood fibres, coconut coir, compost, expanded perlite).

This document is part of a System Standard for plastics piping systems of a particular material for a specified application. System Standards are based on the results of the work being undertaken in ISO/TC 138 "Plastics pipes, fittings and valves for the transport of fluids", which is a Technical Committee of the International Organization for Standardization (ISO). They are supported by separate standards on test methods to which references are made throughout the System Standard. The System Standards are consistent with general standards on functional requirements and on recommended practice for installation. This document does not cover sewage pump chambers, valve chambers and similar products. This document specifies the definitions and requirements for unplasticized polyvinyl chloride (PVC-U), polypropylene (PP) and polyethylene (PE) manholes and inspection chambers having a base with a flow channel and their joints to the piping system, intended for use in non-pressure underground drains and sewers for wastewater, up to a maximum depth of 6 m from ground level to the invert of the flow channel. This document is applicable to manholes and inspection chambers, intended for use buried in the ground outside a building structure only; reflected by the marking of products by "U". This document is applicable to manholes and inspection chambers intended for use in pedestrian or vehicular trafficked areas. NOTE 2 Products complying with this document can also be used in non-traffic areas. NOTE 3 Products complying with this document can be installed in underground applications without additional static calculation. Manhole and inspection chamber components can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, low-pressure moulding or factory fabricated. Manholes and inspection chambers complying with EN 13598-2 are made from a prescribed set of components that are assembled together or manufactured as a single unit. NOTE 4 The complete manhole or inspection chamber assembly also includes items which are not specified in this document (for example near surface or surface components such as covers, frames and gratings complying with the relevant part of EN 124[1]). NOTE 5 Manholes and inspection chambers can be subject to national regulations and / or local provisions.
