Vandens kokybė. Amoniakinio azoto nustatymas vandenyje. Nedidelio užsandarinto vamzdelio metodas (ISO 23695:2023)

This document specifies a method for the determination of ammonium nitrogen (NH4-N) in drinking water, groundwater, surface water, wastewater, bathing water and mineral water using the small-scale sealed tube method. The result can be expressed as NH4 or NH4-N or NH3 or NH3-N. NOTE 1 In the habitual language use of sewage treatment and on the displays of automated sealed-tube test photometers or spectrophotometers, NH4 without indication of the positive charge has become the common notation for the parameter ammonium. This notation is adopted in this document even though not being quite correct chemical nomenclature. This method is applicable to (NH4-N) concentration ranges from 0,01 mg/l to 1 800 mg/l of NH4-N. The measuring ranges of concentration can vary depending on the type of small-scale sealed tube method of different manufacturers. Concentrations even slightly higher than the upper limit indicated in the manufacturers manual relating to the small-scale sealed tube method used, cannot be reported as accurate results. It is up to the user to choose the small-scale sealed tube test with the appropriate application range or to adapt samples with concentrations exceeding the measuring range of a test by preliminary dilution. NOTE 2 The results of a small-scale sealed tube are most precise in the middle of the application range of the test. All manufacturers' methods are based on the Berthelot reaction and its modifications to develop indophenol blue colour. Reagents mixtures can differ slightly based on manufacturers small-scale sealed tube method, see Clause 9. This method is applicable to non-preserved samples by using small-scale sealed tubes for the determination of drinking water, groundwater, surface water, wastewater and to preserved samples. The method is applicable to samples with suspended materials if these materials are removable by filtration.

ISO 11140-4:2007 specifies the performance for a Class 2 indicator to be used as an alternative to the Bowie and Dick-type test for steam sterilizers for wrapped health care goods (instruments, etc. and porous loads). An indicator complying with ISO 11140-4:2007 incorporates a specified material which is used as a test load. This test load may, or may not, be re-usable. ISO 11140-4:2007 does not specify requirements for the test load, but specifies the performance of the indicator in combination with the test load with which it is intended to be used. The indicator specified in ISO 11140-4:2007 is intended to identify poor steam penetration but does not necessarily indicate the cause of this poor steam penetration. This part of ISO 11140-4:2007 does not include test methods to establish the suitability of these indicators for use in sterilizers in which the air removal stage does not include evacuation below atmospheric pressure.

Žemės darbų mašinos. Funkcinė sauga. 2 dalis. Su sauga susijusių valdymo sistemos dalių techninės įrangos projektavimas bei įvertinimas ir architektūrai keliami reikalavimai (ISO/DIS 19014-2:2025)

This document specifies general principles for the development and evaluation of the machine performance level achieved (MPLa) of safety-control systems (SCS) using components powered by all energy sources (e.g. electronic, electrical, hydraulic, mechanical) used in earth-moving machinery and its equipment, as defined in ISO 6165. The principles of this document apply to machine control systems (MCS) that control machine motion or mitigate a hazard; such systems are assessed for machine performance level required (MPLr) per ISO 19014-1 or ISO/TS 19014-5. Excluded from the scope of this document are the following systems: — awareness systems that do not impact machine motion (e.g. cameras and radar detectors); — fire suppression systems, unless the activation of the system interferes with, or activates, another SCS. Other systems or components whereby the operator would be aware of failure (e.g. windscreen wipers, head lights, etc.), or are primarily used to protect property, are excluded from this document. Audible warnings are excluded from the requirements of diagnostic coverage. In addition, this document addresses the significant hazards as defined in ISO 12100 mitigated by the hardware components within the SCS. This document is not applicable to EMM manufactured before the date of its publication.

Šaldymo sistemos ir šilumos siurbliai. Saugos ir aplinkosauginiai reikalavimai. 1 dalis. Pagrindiniai reikalavimai, apibrėžtys, klasifikavimas ir atrankos kriterijai

This document specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants. The term “refrigerating system” used in this document includes heat pumps. This part of EN 378 specifies the classification and selection criteria applicable to refrigerating systems. These classification and selection criteria are used in Parts 2, 3 and 5. This document applies to: a) refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard e.g. [7] b) secondary cooling or heating systems; c) the location of the refrigerating systems; d) replaced parts and added components after adoption of this document if they are not identical in function and in the capacity. Systems using refrigerants other than those listed in Part 5 of this standard are not covered by this document. Clause 7 specifies how to determine the refrigerant quantity safety limit in a given space, which, when exceeded, requires additional protective measures to reduce the risk. This document is not applicable to refrigerating systems which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication. This document is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for existing stationary systems, being transferred to and operated on another site. This document also applies in the case of the conversion of a system to another refrigerant type, in which case conformity to the relevant clauses of Parts 1, 2, 3 and 5 of the standard is expected to be assessed. Product family standards dealing with the safety of refrigerating systems take precedence over horizontal and generic standards covering the same subject.

Geležinkelio taikmenys. Elektromagnetinis suderinamumas. 3-1 dalis. Riedmenys. Traukinys ir sukomplektuotos transporto priemonės

This document specifies the emission limits and immunity requirements for all types of rolling stock. It covers traction stock, hauled stock and trainsets including urban vehicles for use in city streets. The scope of this part of the standard ends at the interface of the rolling stock with its respective energy inputs and outputs. In the case of locomotives, trainsets, trams etc., this is the current collector (pantograph, shoe gear). In the case of hauled stock, this is the AC or DC auxiliary power connector. However, since the current collector is part of the traction stock, it is not entirely possible to exclude the effects of this interface with the power supply line. The slow moving test has been designed to minimize these effects. The frequency range from 150 kHz to 1 GHz is considered sufficient to protect the environment in the whole frequency range from 0 Hz (DC) to 400 GHz. For demonstration of compatibility in this document only measurements at the specified frequencies are required.
