Part 2 of this European standard specifies the minimum safety requirements
and test methods for children's harnesses incorporating backpacks and/or
toys with a leading rein for restraining children when walking, with the ability
to walk competently and for use up to 48 months of age.
If the product has other functions not covered in this European standard,
reference should be made to the relevant European standard.

Part 1 of this European standard specifies the minimum safety requirements
and test methods for strap and/or fabric assemblies for restraining children
from birth up to 48 months of age. These products are provided with a rein for
use when the child is walking and/or may be provided with detachable straps
for use in child use and care articles which are fitted with specified attachment
points.

TC - Correction of technical errors

The purpose of this document is to allow users to determine the fine fraction with the calculation
method. It also describes the assumptions and preconditions to be met in order for this method
to be valid. This calculation method is applicable only after experiments have shown that the
results are accurate and consistently equal or higher than the results from sedimentation, as
described in Part 2, for that particular bulk material.
For preparation of the sample and determination of crysta...view more

TC - Correction of technical errors

This European Standard specifies the design, testing and marking requirements for spring loaded pressure relief valves (PRV), for use in liquefied petroleum gas (LPG) cylinders.
These PRVs can be either an integral part of a cylinder valve (see EN ISO 14245 [3] and EN ISO 15995 [4]) or a separate device.
This European Standard does not exclude the use of other designs of pressure relief devices that provide a similar level of safety.

IEC-63115-2:2021 specifies designations, tests and requirements for the safe operation of sealed nickel-metal hydride cells and batteries used in industrial applications excluding road vehicles.
Since this document covers batteries for various industrial applications, it includes those requirements which are common and minimum to the various applications.

IEC 62485-6:2021 applies to battery installations used for electric off-road vehicles; it does not cover the design of such vehicles.
Examples of the main applications are:
- industrial
• cleaning machines,
• trucks for material handling, for example, lift trucks, tow trucks, automatic guided vehicles,
• electrically propulsed lifting platforms;
- other applications
• electric powered boats and ships.

IEC 62977-2-1:2021(E) specifies standard measurement conditions and measuring methods for determining the optical characteristics of electronic display modules and systems. These methods apply to emissive and transmissive direct view displays that render real 2D images on a flat panel. This document evaluates the optical characteristics of these displays under darkroom conditions. This document applies to the testing of display performance in response to standard analogue or digital input signal...view more

IEC TR 62271-312:2021(E) refers to high-voltage / low-voltage prefabricated substations (hereinafter prefabricated substations) as specified in IEC 62271-202:2014.
This document, among other options as agreed between manufacturer and user, can be used for the transferability of type tests performed on one or more prefabricated substations with a defined set of ratings and arrangement of components to another prefabricated substation with a different set of ratings or different arrangement of co...view more

IEC 62975:2021 provides procedures and guidelines that are intended for the use and maintenance of natural ester liquid in sealed transformers and other electrical equipment.
This document is applicable to natural esters, originally supplied conforming to IEC 62770 and other applicable standards (e.g. ASTM D6871) in transformers, switchgear and electrical apparatus where liquid sampling is practical and where the normal operating conditions specified in the equipment specifications apply.

IEC TS 62607-8-2:2021 There are two types of thermally stimulated current (TSC) measurement methods, classified by the origin of the current. One is generated by the detrapping of charges. The other one is generated by depolarization. The latter is frequently called thermally stimulated depolarization current (TSDC). This part of IEC 62607 focuses on the latter method, and specifies the measurement procedures to be developed for determining polarization properties of metal-oxide interfacial devi...view more

Describes the discharge current waveforms used to simulate human body model (HBM) electrostatic discharges (ESD) and the basic requirements for equipment used to develop and verify these waveforms. This standard covers HBM ESD waveforms for use in general test methods and for application to materials or objects, electronic components and other items for ESD withstand-test or performance-evaluation purposes. The specific application of these HBM ESD waveforms to non-powered semiconductor devices ...view more
