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.

This document specifies general safety requirements and test methods for all pieces of gymnastic and sports equipment and for all pieces of equipment for the use of physical education, training and competition, intended for use supervised by a competent person and not specified in other, individual standards.

This International Standard describes the general principles of acoustic emission testing (AT) of 
materials, components, and structures made of fibre-reinforced polymers (FRP) with the aim of
— materials characterization,
— proof testing and manufacturing quality control,
— retesting and in-service testing, and
— health monitoring.
This International Standard has been designed to describe specific methodology to assess the integrity 
of fibre-reinforced polymers (FRP), components, or structures or to identify critical zones of high 
damage accumulation or damage growth under load (e.g. suitable instrumentation, typical sensor 
arrangements, and location procedures).
It also describes available, generally applicable evaluation criteria for AT of FRP and outlines procedures 
for establishing such evaluation criteria in case they are lacking.
This International Standard also presents formats for the presentation of acoustic emission test data 
that allows the application of qualitative evaluation criteria, both online during testing and by post-test 
analysis, and that simplify comparison of acoustic emission test results obtained from different test 
sites and organizations.
NOTE The structural significance of the acoustic emission cannot in all cases definitely be assessed based on 
AT evaluation criteria only but can require further testing and assessment (e.g. with other non-destructive test 
methods or fracture mechanics calculations).

This document specifies requirements and test methods for the stone shields to be worn by youths and adults of either sex to provide limited protection against lofted stones and debris while riding motorcycles in motocross and other off road activities on dirt roads.
Hence this document contains general and performance requirements for the materials utilised and requirements for sizes, shapes, marking and assembly methodology.
This document is not applicable to stone shield for children and for people with chest girth below 50 cm.

This International Standard describes a test method that covers the determination of fracture resistance of silicon nitride bearing balls at room temperature by the indentation fracture (IF) method, as specified in ISO 26602.
This International Standard is intended for use with monolithic silicon nitride ceramics for bearing balls. It does not include other ceramic materials.
This International Standard is for material comparison and quality assurance.
Indentation fracture resistance, KI, IFR as defined in this International Standard is not to be equated to fracture toughness determined using other test methods such as KIsc and KIpb.

This document specifies a method for the determination of nominal compressive strength of advanced monolithic technical ceramic materials at room temperature.

This document specifies methods for the chemical analysis of impurities present in aluminium oxide powders used as a raw material for fine ceramics.
Aluminium oxide powders are decomposed by acid pressure decomposition, acid decomposition or alkali fusion. The calcium, chromium, copper, iron, magnesium, manganese, potassium, silicon, sodium, titanium, zinc and zirconium contents in the test solution are determined by an inductively coupled plasma-optical emission spectrometer (ICP-OES).

This document specifies grades and mechanical and physical properties of flat washers made of austenitic, ferritic and duplex steel 
grades, designed to be used in bolted joints in combination with bolts, screws, studs and nuts with a specified property class in 
accordance with ISO 3506-1 and ISO 3506-2. These types of washers may also be used with other fasteners such as screws forming 
their own mating thread This part of ISO 3506 is applicable to the following flat captive and non captive washers made of corrosion resistant stainless steel: - plain washers (with or without knurls, ribs or chamfers); - square washers; - square hole washers; -
shaped plateS

This document specifies particular requirements and performance criteria for the design and construction of cast-in situ concrete chimneys as well as prefabricated concrete chimneys. It identifies requirements to ensure the mechanical resistance and stability of concrete chimneys in accordance with the general requirements given in EN 13084-1:2025.
As for chimneys attached to buildings the criteria given in Clause 1 of EN 13084-1:2025 apply.
Unless otherwise stated in the following clauses the basic standard for the design of concrete structures, EN 1992-1-1:2023 applies.

This document outlines the structure and the content of the whole set.
It provides information about the EMC management.
It specifies the performance criteria applicable to the whole standards series.
This part alone is not sufficient to give presumption of conformity to the essential requirements of the EMC-Directive and is intended to be used in conjunction with other parts of this standard.
The informative Annex A describes the characteristics of the railway system which affect electromagnetic compatibility (EMC) behaviour.
Phenomena excluded from the set are Nuclear EM pulse, abnormal operating conditions (e.g. fault conditions) and the induction effects of direct lightning strike.
Emission limits at the railway system boundary do not apply to intentional transmitters within the railway system boundaries.
Safety considerations are not covered by this set of standards.
The biological effects of non-ionizing radiation as well as apparatus for medical assistance, such as pacemakers, are not considered here.

This document is intended to define the electromagnetic environment of the whole railway system including urban mass transit and light rail systems. It describes the measurement method to verify the emissions and gives the cartography values of the fields most frequently encountered.
This document specifies the emission limits of the whole railway system to the outside world.
The emission parameters refer to the particular measuring points defined in Clause 5.
Also, the zones above and below the railway system can be affected by electromagnetic emissions and particular cases need to be considered individually.
For existing railway systems, it is assumed that compliance with the emission requirements of prEN 50121-3-1:2025, prEN 50121-3-2:2025, prEN 50121-4:2025 and prEN 50121-5:2025 will ensure the compliance with the emission values given in this part.
This document gives emission limits for newly built railway systems (not yet in operation) with different characteristics (e.g. higher design speed of the line, static switching components) in comparison with existing railway systems.

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.
