Neorganinės trąšos. Titrimetrinis amoniakinio azoto nustatymas

This document specifies a method for the titrimetric determination of the ammoniacal nitrogen content in inorganic fertilizers (including compound fertilizers), in which nitrogen is found exclusively either in the form of ammonium salts or ammonium salts together with nitrates. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants and where the following category: inorganic fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic fertilizers are not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible. In the case of application to ammonium nitrate fertilizers of high nitrogen content, this document is not applicable to fertilizer product blends. This document is not applicable to fertilizers or fertilizer product blends containing urea, cyanamide, nutrient polymers or other organic nitrogenous compounds.

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).

Medicinos įtaisų gamybai naudojami nerūdijančiojo plieno adatų vamzdeliai. Reikalavimai ir bandymo metodai (ISO 9626:2025)

ISO 9626:2016 applies to rigid stainless steel needle tubing suitable for use in the manufacture of hypodermic needles and other medical devices primarily for human use. It provides requirements and test methods for the tubes manufactured for needles as component used in medical devices. Additional performance testing on the tube aspect may be required when the component is incorporated in the ready-to-use device. It specifies the dimensions and mechanical properties of steel tubing of designated metric sizes 3,4 mm (10 Gauge) to 0,18 mm (34 Gauge). It does not apply to flexible stainless steel tubing because the mechanical properties differ from those specified for rigid tubing in ISO 9626:2016. However, manufacturers and purchasers of flexible tubing are encouraged to adopt the dimensional specifications given in ISO 9626:2016.

This document is part of a System Standard for plastics piping systems of a particular material for a specified application. There are a number of such System Standards. 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 specifies the definitions and requirements for unplasticized polyvinyl chloride (PVC-U), polypropylene (PP) and polyethylene (PE) ancillary fittings and shallow chambers intended for use in non-pressure underground drains and sewers for wastewater. This document is applicable to: a) ancillary fittings and shallow chambers, intended for use buried underground outside the building structure; reflected in the marking of products by "U"; b) ancillary fittings and shallow chambers, intended for use buried underground both outside (application area code “U”) and within the building structure, reflected in the marking of products by "UD". This document also covers the jointing of the ancillary fittings and shallow chambers to the piping system. The document is applicable to the following ancillary fittings: - sealed access fittings; - rodding point covers; - rodding tees; - mechanical saddles. Ancillary fittings according to this document are intended for use in pedestrian areas, except rodding tees and mechanical saddles which can also be used in vehicular trafficked areas. Ancillary fittings can be installed to a maximum depth of 6,0 m from ground level, with the exception of rodding point covers with a maximum depth of 2,0 m. Shallow chambers according to this document are intended for use in private drains located in pedestrian areas above the ground water table, to a maximum depth of 2,0 m from ground level to the invert of the main flow channel. This document covers shallow chambers having a base with a flow channel and their joints to the piping system. Ancillary fittings and shallow chambers can be manufactured by various methods e.g. injection moulding, rotational moulding, spiral winding or fabricated. NOTE 1 Products complying with this document can be used with pipes, fittings and other components conforming to any of the plastics products standards listed in Annex E, providing their dimensions are compatible. NOTE 2 Products complying with this document can be installed in underground applications without additional static calculation. prEN 13598-1:2025 (E) 6 NOTE 3 Ancillary fittings and shallow chambers can be subject to national regulations and / or local provisions.

ISO 8501-1:2007 is a hardback A5-format book in four languages (English, French, German and Swedish), which specifies a series of rust grades and preparation grades of steel surfaces. The various grades are defined by written descriptions together with photographs that are representative examples within the tolerance for each grade as described in words. It is applicable to hot-rolled steel surfaces prepared for painting by methods such as blast-cleaning, hand and power tool cleaning and flame cleaning, although these methods rarely lead to comparable results. Essentially, these methods are intended for hot-rolled steel, but blast-cleaning methods, in particular, could also be used on cold-rolled steel of sufficient thickness to withstand any deformation caused by the impact of the abrasive or the effects of power tool cleaning. This part of ISO 8501 is applicable also to steel substrates that show residues of firmly adhering paint and other foreign matter in addition to residual mill scale.
