This document specifies requirements and guidance for production assurance and reliability management as applicable to the assets and operations associated with exploration drilling, exploitation, processing and transport of petroleum, petrochemical and natural gas resources. It covers the assets and associated activities for upstream, midstream, downstream and petrochemical business categories. It focuses on the production assurance of oil and gas with respect to production and associated activities and covers the analysis of reliability and maintenance of the equipment. This includes a variety of associated systems and equipment in the oil and gas value chain. Production assurance addresses not only hydrocarbon production, but also associated activities such as drilling, pipeline installation and subsea intervention.
The document also supports production assurance and reliability management for lower carbon energy assets and associated operations, e.g. carbon capture and storage (CCS), hydrogen, ammonia, and wind energy. It describes the processes, activities, requirements and guidelines for systematic management, effective planning, execution and use of production assurance and reliability technology.
This document defines 12 processes, of which seven are denoted as core production assurance processes and addressed in this document. The remaining five processes are denoted as interacting processes and while they are outside the scope of this document, information is provided as to how they relate to production assurance and reliability management. The relationship of the core production assurance processes with these interacting processes, however, is within the scope of this document as the flow of information to and from these latter processes is required to ensure that production assurance requirements are fulfilled.
The document specifies how to establish and execute a production assurance programme (PAP) and a reliability management programme (RMP).
This document lists processes and activities that can be initiated to add value for the stakeholder (e.g. operator), where the selected process can depend on their business strategy and application area.
This document is intended for the following users and associated activities by their personnel:
Operators: Production assurance and reliability management activities. Related activities include project management and control, technology development, technology qualification, concept and system design, risk management (including HSE), integrity management, and maintenance management.

This document specifies the method of instrumented indentation test for determination of hardness and other materials parameters for the following three ranges:
macro range: 2 N ≤ F ≤ 30 kN;
micro range: 2 N > F; h > 0,2 µm;
nano range: h ≤ 0,2 µm.
For the nano range, the mechanical deformation strongly depends on the real shape of indenter tip and the calculated material parameters are significantly influenced by the contact area function of the indenter used in the testing machine. Therefore, careful calibration of both instrument and indenter shape is required in order to achieve an acceptable reproducibility of the materials parameters determined with different machines.
The macro and micro ranges are distinguished by the test forces in relation to the indentation depth.
Attention is drawn to the fact that the micro range has an upper limit given by the test force (2 N) and a lower limit given by the indentation depth of 0,2 µm.
The determination of hardness and other material parameters is given in the normative Annex A.
At high contact pressures, damage to the indenter is possible. For test pieces with very high hardness and modulus of elasticity, permanent indenter deformation can occur and can be detected using suitable reference materials. Indentations that result in damage or permanent deformation of the indenter are excluded from the scope of this test method.
This test method can also be applied to thin metallic and non-metallic coatings and non-metallic materials. In this case, it is recommended that the specifications in the relevant standards be taken into account (see also 7.3 and ISO 14577-4).
The analysis methods of this standard assume that materials behave like ideal materials. Any deviation (internal stress, pile-up, sink-in, densification, phase transitions, cracks) will result in additional uncertainties. This becomes especially important if comparisons shall be done to material parameters, obtained with other methods.

This document defines and describes the concept of on-boarding of person identification data (PID) within a Wallet. The scope of this document includes cases where a natural person is the User in control of a Wallet. This includes a natural person who is in control of their own information, as well as natural persons who control information to represent another natural person or a legal person. This document considers a single set of PID attributes linked to a single Wallet Unit. This does not exclude the issuance of multiple PIDs representing the same set of PID attributes, e.g. batch issuance.
It also provides the general workflow, the roles and responsibilities at stake, and links the on-boarding with the Level of Assurance concept underpinning eIDAS [1];
The scope of this document includes cases where a natural person is the User in control of a wallet. This includes a natural person who is in control of their own data as well as natural persons who control data to represent another natural person or legal person.
EXAMPLE If a natural person represents a legal person, the PID provider can issue a "representation PID" in an own Wallet Unit for representation purposes controlled by the natural person Wallet User. The "representation PID" is a kind of attestation which contains PID about the natural person (representative) and about the legal person (representee).
This document is limited to the on-boarding of an unique set of person identification data, complying with the legal provisions of eIDAS [1], in particular (1) issued in accordance with Union or National laws, and (2) conformant with the relevant implementing act [5].
The following aspects are out of scope of this document:
— the on-boarding of person identification data within a Wallet where the User is a legal person;
— other types of on-boarding, such as:
— provisioning of person identification data after revocation, expiration or deletion;
— addition of other Attributes (under the shape of attestations) in accordance with the requirement of Level of Assurance “High” which are not part of the set of person identification data but are part of the legal identity under National’s laws;
— management of person identification data (deletion, update, etc.);
— provisioning of person identification data which is not compliant with the relevant implementing act [5];
— provisioning of a partial set of person identification data;
— provisioning of supplemental set(s) of person identification data (multiple PIDs);

This document specifies procedures for the detection of a DNA sequence of a construct used to (genetically) enhance the growth of fish commonly found in aquaculture. The genetically modified AquAdvantage Atlantic salmon (Salmo salar) carries the construct expressing CS-GHc2 growth hormone and can be detected based on a real-time polymerase chain reaction (PCR) targeting either the border between the growth hormone coding sequence (CS-GHc2) of Oncorhynchus tshawytscha (Chinook salmon) and the antifreeze terminator (T-AFP) of (Macro-) Zoarces americanus (ocean pout), i.e. with the construct-specific method, or the border between the Atlantic salmon genomic DNA and the antifreeze promoter (P-AFP) of ocean pout, i.e. with the event-specific method. These methods can be applied to identify the genetically modified (GM) fish or for screening purposes.
This document is applicable for the analysis of DNA extracted from foodstuffs. It can also be suitable for the analysis of DNA extracted from other products such as feedstuffs. The application of these methods requires the extraction of an adequate amount of amplifiable DNA from the relevant matrix.

This document is directly applicable to pulsed X-radiation with pulse duration of 0,1 ms up to 10 s. This range covers the whole range used in medical diagnostics at the time of publication. Some specifications can also be applicable for much shorter pulses; one example is the air kerma of one pulse. Such a pulse can be produced, e.g. by X-ray flash units or high-intensity femtosecond-lasers. Other specifications are not applicable for much shorter pulses; one example is the time-dependent behaviour of the air kerma rate. This cannot be measurable for technical reasons as no suitable instrument is available, e.g. for pulses produced by a femtosecond-laser.
This document specifies the characteristics of reference pulsed radiation for calibrating and testing radiation protection dosemeters and dose rate meters with respect to their response to pulsed radiation. At this point, it is only concerned with the characteristics of single pulses. Single pulses are the most difficult for dosemeters to measure. Determining the dose for repeated pulses is easier, but still more difficult than for continuous radiation, i.e. the performance of the dosemeters when measuring repeated pulses lies between these extremes. The radiation characteristics includes the following:
time-dependent behaviour of the air kerma rate of the pulse;
time-dependent behaviour of the X-ray tube high voltage during the pulse;
uniformity of the air kerma rate within a cross-sectional area of the radiation beam;
air kerma of one radiation pulse;
air kerma rate of the radiation pulse;
repetition frequency.
This document does not define new radiation qualities but uses those radiation qualities specified in existing ISO and IEC standards. Instead, this document gives the link between the parameters for pulsed radiation and the parameters for continuous radiation specifying the radiation qualities. It does not specify specific values or series of values for the pulsed radiation field but specifies only those limits for the relevant pulsed radiation parameters that are required for calibrating dosemeters and dose rate meters and for determining their response depending on the said parameters.
The pulse parameters with respect to the phantom-related quantities were determined using conversion coefficients according to ISO 4037 (all parts). This is possible as the radiation qualities specified in existing ISO and IEC standards are used.
A given reference pulsed X-ray facility is characterized by the parameter ranges over which the full specifications and requirements according to this document are met. Therefore, not all reference pulsed X-ray facilities can produce pulses covering the same parameter ranges.
