This document gives a method for determining the resistance to cracking of steel pipes in sour service.
This test method employs a full-scale test specimen consisting of a short length of pipe (a ‘full ring’), sealed at each end to contain the sour test environment within. The test method applies to any pipe; seamless, longitudinally welded (with or without filler), helical welded, and to girth welds between pipes.
NOTE 1 The specimen is usually a pipe but can also consist of flange neck or section of a bend, or other tubular component or a combination of the above.
NOTE 2 This test method can also be used for corrosion resistant alloys (CRAs).
The method utilizes ovalization by mechanical loading to produce a circumferential stress, equal to the target hoop stress, at two diametrically opposite locations on the inside surface of the test specimen.
The test specimen is then subjected to single sided exposure to the sour test environment
NOTE 3 The test also allows measurement of hydrogen permeation rates.
WARNING — The use of this document can involve hazardous materials, operations and equipment. It does not purport to address all of the safety or environmental problems associated with its use. Attention is drawn to local and national regulations regarding use of hazardous materials, in particular for hydrogen sulfide.

This document addresses the measurement of source terms for environmental noise calculation for rail traffic (including light rail, such as trams, metros, etc). It is applicable to the measurement of in-service trains on operational tracks.
It is not applicable to type acceptance testing of rolling-stock or tracks, or to derive source terms for time domain models.
The following rail traffic noise source types are in the scope:
• Rolling noise ;
• Traction noise ;
• Aerodynamic noise ;
• Impact noise (e.g. rail joints, switch and crossings, wheel flats) ;
• Braking noise ;
• Bridge noise ;
• Squeal noise.
Noise from rail vehicles at standstill, such as stationary engine idling and auxiliary equipment at yards and stations is covered by EN ISO 3095:2013 for measurement procedures and operating conditions, and by ISO 3740:2019, and ISO 3744:2010 for the determination of sound power.
The calculation of the propagation of sound is part of generally standardized propagation models which are not addressed in this document.

1.1 This document specifies the constructional requirements for fans constructed to Group II G (of explosion groups IIA, IIB and hydrogen) categories 1, 2 and 3, and Group II D categories 2 and 3, intended for use in explosive atmospheres. NOTE 1 Operation conditions for the different categories of fans used in this document are defined in Clause 4. NOTE 2 For category 1 D fans, requirements provided in this document are not sufficient to ensure safety. In addition, explosion protection measures as specified in EN 1127 1:2019 are required to prevent ignition in the case of rare malfunctions. NOTE 3 Technical requirements for explosion group IIC (other than hydrogen) are not given in this document. Where such atmospheres are present, additional explosion protection measures as specified in EN 1127 1:2019 can be needed. 1.2 This document does not apply to group I fans (fans for mining), cooling fans or impellers on rotating electrical machines, cooling fans or impellers on internal combustion engines, vehicles or electric motors. NOTE 1 Requirements for group I fans are given in EN ISO/IEC 80079 38:2016. NOTE 2 The requirements for electrical parts are covered by references to electrical equipment standards. 1.3 This document specifies requirements for design, construction, testing and marking of complete fan units intended for use in potentially explosive atmospheres in air containing gas, vapour, mist and/or dusts. Such atmospheres can exist inside (the conveyed atmosphere (flammable or not)), outside, or inside and outside of the fan. NOTE This document covers mechanical equipment, in particular fans. The “protection concept” as specified in EN ISO 80079 37:2016 is constructional safety. Requirements for marking are given in EN ISO 80079 37:2016. 1.4 This document is applicable to fans working in ambient atmospheres and with normal atmospheric conditions at the inlet, having — absolute pressures ranging from 0,8 bar to 1,1 bar, — and temperatures ranging from −20 °C to +60 °C, — and maximum volume fraction of 21 % oxygen content, — and an aerodynamic energy increase of less than 25 kJ/kg. NOTE 1 25 kJ/kg is equivalent to 30 kPa at inlet density of 1,2 kg/m3. This document can also be helpful for the design, construction, testing and marking of fans intended for use in atmospheres outside the validity range stated above or in cases where other material pairings need to be used. In this case, the ignition risk assessment, ignition protection provided, additional testing (if necessary), manufacturer's marking, technical documentation and instructions to the user, clearly demonstrate and indicate the equipment's suitability for the conditions the fan can encounter. NOTE 2 Temperatures below −20°C can be considered. Material suitability can require specific evaluation for these temperatures. With lower temperature the explosion pressure increases, which leads to increased test pressures (see A.3) and can require specific testing. Although the standard atmospheric conditions in EN ISO 80079 36:2016 give a temperature range for the atmosphere of −20 °C to +60 °C the normal ambient temperature range for the equipment is −20 °C to +40 °C unless otherwise specified and marked.

This document:
— defines a reference Land Administration Domain Model (LADM) covering basic information-related components of land administration/georegulation;
— provides an abstract, conceptual model with packages related to:
— parties (people and organizations);
— basic administrative units, rights, responsibilities, and restrictions;
— spatial units.
— provides terminology for 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;
— provides a platform for indicators-based comparison and monitoring;
— provides a content model independent of encoding, allowing for the support of various encodings;
— provides a basis for national and regional profiles;
— enables the combining of land administration/georegulation information from different sources in a coherent manner.
The following are outside the scope of this document:
— interference with (national) land administration/georegulation laws that may have any legal implications;
— construction of external databases with party data, address data, land cover data, physical utility network data, archive data and taxation data. However, the LADM provides stereotype classes for these data sets to indicate which data set elements the LADM expects from these external sources, if available.
This document provides the concepts and basic structure for standardization in the land administration/georegulation domain. It defines a general schema that permits regulatory information to be described. It also allows for the relationship to multiple parties and groups to be expressed
together with a referencing structure so that sourcing of all information systems may be maintained.
This document establishes the common elements and basic schema upon which more detailed schema may be established. Other parts of ISO 19152 will address specific areas of the land administration paradigm building upon the common core schema defined in document.

This document specifies a method of determining the apparent density, i.e. the mass per unit of volume, of loose material that cannot be poured from a funnel of specified design.
NOTE For a method of determining the apparent density of loose moulding material that can be poured from a specified funnel, see ISO 60.
This document applies to loose moulding materials such as slice, granular or powder.
When the method is applied to relatively coarse materials, rather variable results may be obtained, owing to the error introduced when a straightedge blade is drawn across the top of the cylinder.
A knowledge of apparent density is of limited value in estimating the relative fluffiness or bulk of moulding materials, unless their densities in the moulded condition are approximately the same.

The scope of this Recommendation | International Standard is threefold.
This Recommendation | International Standard provides guidance on how to prepare new and old protocols for cryptographic algorithm migration, and defines auxiliary cryptographic algorithms to be used for migration purposes.
This Recommendation | International Standard specifies a general wrapper protocol that provides authentication, integrity and confidentiality (encryption) protection for other protocols. This wrapper protocol includes a migration path for cryptographic algorithms allowing for smooth migration to stronger cryptographic algorithms as such requirements evolve. This will allow migration to quantum-safe cryptographic algorithms. Protected protocols can then be developed without taking security and cryptographic algorithms into consideration.
This Recommendation | International Standard also includes some protocols to be protected by the wrapper protocol primarily for support of public-key infrastructure (PKI). Other specifications, e.g., Recommendations or International Standards, may also develop protocols designed to be protected by the wrapper protocol.
