Annex B gives an overview on specific testing techniques of standards linked to quality levels, acceptance levels and testing methods.

IEC 60269-3:2024 is divided into four fuse systems, each dealing with a specific example of standardized fuses for use by unskilled persons. This part applies to “gG” fuses only. Unskilled persons do not have technical knowledge or sufficient experience. To avoid dangers, which electricity may create, the relevant part of the fuse standard shall provide requirements for maximum safety in service. IEC 60269-3 provides four systems for use by unskilled persons. Instructions for the safe operation of fuse-links are provided in the manufacturer’s literature. All systems provide their own mechanical solution to avoid the use of a fuse-link with higher current rating (non-interchangeability) whereas the protection of cables and lines is ensured. The applicant is required to take care to replace a fuse-link by the same type.

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.

This document is applicable to lead-acid batteries with a nominal voltage of 12 V, used primarily as power source for the starting of internal combustion engines (ICE), lighting and also for auxiliary equipment of ICE vehicles. These batteries are commonly called "starter batteries". Batteries with a nominal voltage of 6 V are also included in the scope of this document. All referenced voltages need to be divided by two for 6 V batteries. The batteries under the scope of this document are used for micro-cycle applications in vehicles which can also be called Start-Stop (or Stop-Start, idling-stop system, micro-hybrid or idle-stop-and-go) applications. In cars with this special capability, the internal combustion engine is switched off during a complete vehicle stop, during idling with low speed or during idling without the need of supporting the vehicle movement by the internal combustion engine. During the phases in which the engine is switched off, most of the electric and electronic components of the car need to be supplied by the battery without support of the alternator. In addition, in most cases an additional regenerative braking (recuperation or regeneration of braking energy) function is installed. The batteries under these applications are stressed in a completely different way compared to classical starter batteries. Aside of these additional properties, those batteries need to crank the ICE and support the lighting and also auxiliary functions in a standard operating mode with support of the alternator when the internal combustion engine is switched on. All batteries under this scope need to fulfil basic functions, which are tested under application of EN 50342 1:2015.
This document is applicable to batteries for the following purposes:
-   Lead-acid batteries of the dimensions according to EN 50342 2 for vehicles with the capability to automatically switch off the ICE during vehicle operation either in standstill or moving (“Start-Stop”);
-   Lead-acid batteries of the dimensions according to EN 50342 2 for vehicles with Start-Stop applications with the capability to recover braking energy or energy from other sources.
This document is not applicable to batteries for purposes other than mentioned above, but it is applicable to EFB delivered in dry-charged conditions according to EN 50342 1:2015, Clause 7.
NOTE   The applicability of this document also for batteries according to EN 50342 4 is under consideration.

This document specifies requirements for enhanced visibility equipment in the form of garments, or devices, which are capable of visually signalling the user’s presence.
The enhanced visibility equipment is intended to provide conspicuity of the wearer in medium risk situations under any daylight conditions and/or under illumination by vehicles headlights or searchlights in the dark.
Performance requirements are included for colour and retroreflection as well as for the minimum areas and for the placement of the materials in protective equipment.
This document is not applicable to:
-   high visibility equipment in high-risk situations, which is covered in EN ISO 20471 (for further information concerning risk situations, see Annex A);
-   visibility equipment specifically intended for the head, hands and feet, e.g. helmets, gloves and shoes;
-   equipment integrating active lighting, e.g. LEDs;
-   visibility for low-risk situations.

The present document specifies technical characteristics and methods of measurements for Point-to-point (P-P) Digital Fixed Radio Systems (DFRS) operating in frequency bands allocated to Fixed Service (FS) from 1 GHz to 174,8 GHz, corresponding to the appropriate frequency bands from 1,4 GHz to 174,8 GHz as described in relevant annexes B through L. Systems in the scope of the present document are generally intended to operate in full Frequency Division Duplex (FDD) and cover also unidirectional links applications. Time Division Duplex (TDD) applications, when possibly applicable in a specific band, are explicitly mentioned as appropriate in the relevant annexes B through L. Other possible prescriptions, limitations and requirements, for operation in specific bands are also explicitly mentioned, as appropriate, in the relevant annexes B through L. Systems in the scope of the present document are intended to operate only in combination with directive fixed gain antennas respecting the technical requirements in ETSI EN 302 217-4 [6]. Systems in the scope of the present document may be composed by equipment without antennas (see informative annex Q for background) or equipment including integral (but physically detachable) or dedicated antenna. Systems including integral antennas physically undetachable from the radio equipment are not in the scope of the present document (see note 1).
NOTE 1: For additional information, the rationale is that the present document as well as ETSI EN 301 126-1 [1] (radio equipment parameters testing) do not provide radiated test methods and ETSI EN 301 126-3-1 [2] (antenna parameters testing) does not provide test methods for undetachable antennas; future revisions could fill this vacancy.
NOTE 2: The relationship between the present document and the essential requirements of article 3.2 of Directive 2014/53/EU [i.1] is given in annex A.

This document gives requirements and guidance on security controls and implementation for third-party payment service providers (TPPSPs).

The present document can be used by independent bodies as the basis for confirming that a TSP can be trusted for issuing time-stamps. The present document does not specify protocols used to access the TSUs.
NOTE 1: A time-stamping protocol is defined in IETF RFC 3161 [i.2] including optional update in IETF RFC 5816 [i.3] and profiled in ETSI EN 319 422 [5].
The present document does not specify how the requirements identified can be assessed by an independent party, including requirements for information to be made available to such independent assessors, or requirements on such assessors.
NOTE 2: See ETSI EN 319 403-1 [i.9] for guidance on assessment of TSP's processes and services.
NOTE 3: The present document references ETSI EN 319 401 [4] for general policy requirements common to all classes of TSP's services.

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:
- parallel running of AC and DC electric traction power supply systems;
- 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 specifies a test method for determining the mechanical viscoelastic properties of interlayer materials.

Parameters of the Prony series, widely used in numerical simulation, can be derived from the measurements in Annex C.

This document specifies the characteristics of prevailing torque hexagon high nuts (with non‑metallic insert), 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 equal to mmin (as specified in ISO 898-2 and ISO 4033 for style 2) plus the prevailing torque feature. The height of the prevailing torque feature (hmax – mmin) for the non-metallic insert is identical for regular, high and thin nuts for a given diameter.
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.

This document applies to the determination of beta emitters activity concentration using liquid scintillation counting. The method requires the preparation of a scintillation source, which is obtained by mixing the test sample and a scintillation cocktail. The test sample can be liquid (aqueous or organic), or solid (particles or filter or planchet).
NOTE            Planchet are samples, described in 8.5, out of solid material e.g. small metal, plastic or glass pans or support material made of these materials
This document describes the conditions for measuring the activity concentration of beta emitter radionuclides by liquid scintillation counting[2].
The choice of the test method using liquid scintillation counting involves the consideration of the potential presence of other beta-, alpha- and gamma emitter radionuclides in the test sample. In this case, a specific sample treatment by separation or extraction is implemented to isolate the radionuclide of interest in order to avoid any interference with other beta-, alpha- and gamma-emitting radionuclides during the counting phase.
This document is applicable to all types of liquid samples having an activity concentration ranging from about 1 Bq·l−1 to 106 Bq·l−1. For a liquid test sample, it is possible to dilute liquid test samples in order to obtain a solution having an activity compatible with the measuring instrument. For solid samples, the activity of the prepared scintillation source shall be compatible with the measuring instrument.
The measurement range is related to the test method used: nature of test portion, preparation of the scintillator - test portion mixture, measuring assembly as well as to the presence of the co-existing activities due to interfering radionuclides.
Test portion preparations (such as distillation for 3H measurement, or benzene synthesis for 14C measurement, etc.) are outside the scope of this document and are described in specific test methods using liquid scintillation[3][[4][5][6][7][8][9][10].

This document specifies the method for non-destructive thickness measurement via the magnetic type of electrodeposited nickel coatings, also called “e-nickel”, on magnetic or non-magnetic substrates.
It is possible that the method is not applicable to autocatalytic (electroless) nickel coatings, since these coatings are often non-magnetic due to their chemical composition.
For the purposes of this document, two types of substrates are distinguished:
a)       nickel coatings on magnetic substrates (type A coatings);
b)       nickel coatings on non-magnetic substrates (type B coatings).
Not all instruments are applicable to both types of coating.
The effective measuring ranges of instruments using the principle of magnetic attraction are up to 50 µm for type A coatings and up to 25 µm for type B coatings.
For instruments using the principle of reluctance, the effective ranges are much greater, up to 1 mm or even more. This method is applicable to both types of coatings.

This document specifies the general conditions and procedures observed when testing coated test specimens by exposing them to constant condensation-water atmospheres or alternating condensation-water atmospheres, in a cabinet with a heated water reservoir. These conditions and procedures ensure that the results of tests carried out in different laboratories are reproducible.
This document does not cover the shape and preparation of the test specimens, the duration of the test and the assessment of the test results.

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 specifies a method for the determination of the length, width and straightness of bitumen sheets for roof waterproofing.

This document specifies three methods for the determination of the density of non-cellular plastics in the form of void-free moulded or extruded objects, as well as powders, flakes and granules.
—     Method A: Immersion method, for solid plastics (except for powders) in void-free form.
—     Method B: Liquid pycnometer method, for particles, powders, flakes, granules or small pieces of finished parts.
—     Method C: Titration method, for plastics in any void-free form.
NOTE            Density is frequently used to follow variations in physical structure or composition of plastic materials. Density can also be useful in assessing the uniformity of samples or specimens. Often, the density of plastic materials depend upon the choice of specimen preparation method. When this is the case, precise details of the specimen preparation method are intended to be included in the appropriate material specification. This note is applicable to all three methods.
Annex C provides further information for calculating the volume of the specimen used for the determination of the density in the case that method A (the immersion method) is applied.
