This document specifies methods and metrics for assessing the accuracy and precision of 3D scanned data for use in 3D printing, throughout the full 3D printing lifecycle. This document focuses mainly on 3D scanned data from computed tomography. Computed tomography can acquire information concerning the internal structures, regional density, orientation and/or alignment of scanning objects, as well as their shape and appearance. This document is applicable to the assessment of image-based modelling, segmentation, and 3D models. This document is not intended to assess the 3D printed product itself.

This document sets out principles and procedures for testing the bias of test samples of coals or cokes, taken according to the ISO 13909 series.

This document specifies the characteristics of prevailing torque (all metal) hexagon regular nuts, in steel and stainless steel, with metric coarse pitch thread M5 to M39, and with product grades A and B.
NOTE            These nuts are designed with an overall height hmin = mmin (as specified in ISO 898-2 and ISO 4032 for style 1) plus the prevailing torque feature. hmax has been established in function of hmin; therefore, the tolerance (hmax – hmin) does not follow the ISO code system for tolerances (IT system).
If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.

General
1.1 RO.1 General
(ncpt) This standard EN 50341-2-24 (Part 2-24) gives the requirements for design and construction of overhead electrical lines with nominal voltages exceeding A.C. 1 kV operating at 50 Hz frequency.
This Part 2-24 applies to new overhead electrical lines, as well as in the following cases:
- the extension of existing overhead electrical lines;
- the deviation of some portions of the existing overhead electrical lines in accordance with the provisions of technical regulations in force issued by the National Energy Regulatory Authority (see article 39 of ANRE Order 25/2016);
- new supports to be used for the replacement and/or relocation of existing supports.
This Part 2-24 is not applicable for the existing overhead electrical lines unless specifically required by Project Specification. The overhead electrical lines, that are in different stages of design or construction, can be completed in conformity with the standards in force at the beginning of project.
For the application of this standard for specific requirements relating to modernization, increasing safety and transport capacity of existing overhead electrical lines, reference shall be specified in the Project Specification. At the same time, the correlation between relevant regulations and associated standards shall be established in the Project Specifications.
The extension of existing electrical lines is considered as new overhead electrical lines, except the junction points that shall be detailed in the Project Specifications.
1.2    Field of application
1.2        RO.1    Overhead electrical lines having uninsulated, pre-insulated and insulated conductors
(ncpt)   This Part 2-24 is applicable for the design and construction of overhead electrical lines with uninsulated, pre-insulated and insulated conductors where the internal and external clearances can be smaller than those specified in Part 1 (SR EN 50341-1:2013).

This document specifies methods for the determination of components in plastics that can be extracted by hot organic liquids near their boiling points. It also specifies a special extraction method called cold-extraction.
The extractable components can be monomers, oligomers, polymers, plasticizers, stabilizers, etc. The kind and percentage of extractable matter influence the properties of plastics.
This document does not apply to plastics that come into contact with food or drinking water, because special regulations for those plastics are established in many countries. The methods of this document are not intended to be used for migration tests.
If this document is used to test plastics other than those mentioned in Table 1, the operating conditions are intended to be agreed upon by the interested parties.

This document specifies requirements for the protective provisions relating to electrical safety in fixed installations, when it is reasonably likely that hazardous voltages or currents will arise for people or equipment, as a result of the mutual interaction of AC and DC electric power supply traction systems.
It also applies to all aspects of fixed installations that are necessary to ensure electrical safety during maintenance work within electric power supply traction systems.
The mutual interaction can be of any of the following kinds:

- crossing of AC and DC electric traction power supply systems;
- shared use of tracks, buildings or other structures;
- system separation sections between AC and DC electric traction power supply systems.
The scope is limited to galvanic, inductive and capacitive coupling of the fundamental frequency voltages and currents and their superposition.
This document applies to all new lines, extensions and to all major revisions to existing lines for the following electric traction power supply systems:
a)   railways;
b)   guided mass transport systems such as:
1)   tramways,
2)   elevated and underground railways,
3)   mountain railways,
4)   magnetically levitated systems, which use a contact line system,
5)   trolleybus systems, and
6)   electric traction power supply systems for road vehicles, which use an overhead contact line system;
c)   material transportation systems. The document does not apply to:
a)   electric traction power supply systems in underground mines;
b)   cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) in so far as these are not supplied directly or via transformers from the contact line system and are not endangered by the electric traction power supply system for railways;
c)   suspended cable cars;
d)   funicular railways;
e)   procedures or rules for maintenance.
The rules given in this document can also be applied to mutual interaction with non-electrified tracks, if hazardous voltages or currents can arise from AC or DC electric traction power supply systems.

This document:
a)       builds on the models established in ISO 19152-1 and ISO 19152-2 to cover the valuation aspect of the Land Administration Domain Model (LADM);
b)       provides an abstract conceptual model covering:
1)       values (assessed values, valuation procedures, mass valuation);
2)       transaction prices;
3)       sales statistics;
4)       valuation units (parcel (legal space parcel), building, condominium unit, valuation unit group).
c)        provides terminology for the valuation component of land administration/georegulation, based on various national and international systems, that is as simple as possible in order to be useful in practice. The terminology allows a shared description of different formal or informal practices and procedures in various jurisdictions;
d)       specifies a content model independent of encoding that can be employed as a basis for local, national and regional profiles for valuation processes; and
e)       enables the combining of valuation information from different sources in a coherent manner.
NOTE            This document does not interfere with national property valuation-related regulations with potential legal implications.

This document specifies a procedure for the determination of fluorine in copper and zinc sulfide concentrates by sodium hydroxide fusion and fluoride ion selective electrode (FISE) detection. Fluoride ions are leached from the sodium hydroxide fusion and presented to the FISE. Potential interfering ions are masked by the use of a complexing agent and control of solution pH. If the aluminium content in the concentrate is up to a mass fraction of 4,5 %, there is no effect of aluminium in this method. However, if the aluminium content in the concentrate exceeds a mass fraction of 4,5 %, there is a possibility that it can affect the analytical results. The method is applicable to fluorine in the following ranges: — copper concentrates: mass fraction of 0,008 % to 0,3 %; — zinc concentrates: mass fraction of 0,005 % to 0,1 %. The results of the trueness test can be found in Annex C.

This document specifies a reference method for the determination of volatile organic compound (VOC) emissions into indoor air from floor covering adhesives and products used for flooring installation. This method is used to determine volatile organic compounds, semi-volatile organic compounds, and volatile aldehydes. It is based on the use of a test chamber and subsequent analysis of an air sample for organic compounds by GC-MS respectively HPLC. The main purpose of the test procedure is to obtain relevant performance data for the classification of flooring adhesives and products used for the installation of floor coverings with respect to low VOC emissions during the use phase of the flooring.

This document provides procedures for monitoring the dose to the skin, the extremities, and the lens of the eye. It gives guidance on how to decide if such dosemeters are needed and to ensure that individual monitoring is appropriate to the nature of the exposure, taking practical considerations into account. This document specifies procedures for individual monitoring of radiation exposure of the skin of the body, extremities (skin of the hands, fingers, wrists, forearms including elbow, lower leg including patella, feet and ankles), and lens of the eye in planned exposure situations. It covers practices which involve a risk of exposure to photons in the range of 8 keV to 10 MeV, electrons and positrons in the range of 0,07 MeV to 1,2 MeV mean beta energies being equivalent to 0,22 MeV and 3,6 MeV beta maximum energy - in accordance to the ISO 6980 series, and neutrons in the range of thermal to 20 MeV. This document gives guidance for the design of a monitoring programme to ensure compliance with legal individual dose limits. It refers to the appropriate operational dose quantities, and it gives guidance on the type and frequency of individual monitoring and the type and positioning of the dosemeter. Finally, different approaches to assess and analyse skin, extremity, and lens of the eye doses are given. It is not in the scope of this document to consider exposure due to alpha radiation fields. NOTE 1 The requirements for the monitoring of the occupational exposure may be given in national regulations. NOTE 2 Dose to the lens of the eye due to intake of tritium is not in the scope of this document. Moreover, the situation of the workers that work in contaminated atmosphere and can have alpha and/or radon eye lens dose is also not in the scope.
