This European Standard describes techniques for the manual, pulse-echo, ultrasonic testing of forgings manufactured from austenitic and austenitic-ferritic stainless steels. Mechanized scanning techniques, such as immersion testing, may be used but should be agreed between the purchaser and supplier (see Clause 4).
This part of EN 10228 applies to four types of forgings, classified according to their shape and method of production. Types 1, 2 and 3 are essentially simple shapes. Type 4 covers complex shapes.
This part of EN 10228 does not apply to:
- closed die forgings;
- turbine rotor and generator forgings.
Ultrasonic testing of ferritic and martensitic steel forgings is the subject of Part 3 of this European Standard.

This document specifies the requirements and test methods for durability and strength of hardware for vertical and horizontal pivot windows and door height windows (including pivot hinges and central locking systems).
If the hardware manufacturer would like to classify an integrated restrictor function, the pivot hinges can be tested in accordance with EN 13126-5.
This document does not apply to manoeuvring devices which are covered in EN 13126-2, EN 13126-3, and EN 13126-14.

This document covers hinged/pivoted and sliding doorsets with engaging fasteners (e.g. latches, deadbolts) for pedestrian use. It defines the test methods to determine the forces to open/close doors and to engage/release and lock/unlock the building hardware using a key or handle. It is only applicable to the manual operation of doorsets.
These doorsets can include:
— emergency or panic exit devices;
— door closing devices.
NOTE The use of some windows involves engaging fasteners (e.g. latches, deadbolts) and can be tested in accordance with this document. Throughout the text where “door leaf”/”door leaves” is written this can also be read as “casements”/”sashes”.

This document provides requirements and guidelines for comparing the life cycles of bio-based products with their fossil-based equivalents.
NOTE The term "equivalents" generally refers to the "functional equivalence".
This document builds on existing LCA methodology and provides requirements and guidance on specific topics relevant for making well-balanced comparisons.

This document specifies a method for the sampling of NO2 in ambient air using diffusive sampling followed by extraction and analysis by colourimetry or ion chromatography (IC). It can be used for the NO2 measurement in a concentration range of approximately 3 µg/m3 to 130 µg/m3 [12]. A sample is typically collected for a period of 1 to 4 weeks [14], with exposure periods depending on the design of the samplers and the concentration levels of NO2.
Several sorbents can be used for trapping NO2 in ambient air using a diffusive sampler [15]. This document specifies the application of triethanolamine as the reagent.
This document describes the application of a tube-type sampler (with either a cylindrical or a slightly conical tube), a badge-type sampler and a radial-type sampler.
The relative expanded uncertainty of NO2 measurements performed using these tube-type diffusive samplers can potentially be lower than 25 % for individual measurements. When aggregating results to form annual average values, the relative expanded uncertainty can be further reduced to levels below 15 % due to the reduction of random effects on uncertainty [9].
NOTE NO2 passive samplers are also employed to measure NOx with the addition of an oxidant to convert ambient NO into NO2. A second NO2 sampler is also deployed without the oxidant and the concentration of NO is determined from the difference of the two samplers [16].

The objective of implementing the pan-European in-vehicle emergency call system (eCall) is to automate the notification of a traffic accident, wherever in Europe, with the same technical standards and the same quality of services objectives by using ‘Public Land Mobile Networks’(PLMN), which supports the European pre-assigned emergency destination address (see normative references) and to provide a means of manually triggering the notification of an incident.
This document specifies the general operating requirements and intrinsic procedures for in-vehicle emergency call (eCall) services in order to transfer an emergency message from a vehicle to a Public Safety Answering Point (PSAP) in the event of a crash or emergency, via an eCall communication session and to establish a voice channel between the in-vehicle equipment and the PSAP.
Private third party in-vehicle emergency supporting services can also provide a similar eCall function by other means. The provision of such services are defined in EN 16102, and are outside the scope of this document.
The communications protocols and methods for the transmission of the MSD are not specified in this document.
This document specifies the operating requirements for an eCall service. An important part of the eCall service is a Minimum Set of Data (MSD). The operating requirements for the MSD are determined in this document, but the form and data content of the MSD is not defined herein. A common European MSD is determined in EN 15722.
This document does not specify whether eCall is provided using embedded equipment or other means (for example in the case of aftermarket equipment).
