This standard specifies the requirements for the training of citizen science divers. The standard shall have a broad scope so as to be applicable to all disciplines of science. 
This document is applicable to all recreational divers independent of any scientific background (unlike the ISO 8804 standard series which a primarily directed at the scientific diving community).

A citizen science diver is competent in basic underwater scientific methodologies and protocols and shall be able to assist in scientific diving activities. 

This standard will specify competencies, prerequisites for training, Introductory information, Required theoretical knowledge, Required practical skills, Practical training parameters and Evaluation criteria for training systems aimed at training citizen science divers.

This document specifies safety requirements and their verification for the design and construction of front loaders designed to be mounted on agricultural and forestry tractors (as defined in the Regulation EU 167/2013).
It deals with all significant hazards, hazardous situations and events relevant to front loaders when used as intended and under the conditions of misuse which are reasonably foreseeable. This includes hazards related to the handling of unit loads during operations (for example, using bale forks), hazards related to mounting/demounting the lifting arms to/from the frame mounted on the tractor, and also hazards related to devices for mounting/demounting attachments to/from the lifting arms.
In addition, it specifies the type of information on safe working practices.
Hazards related to the mounted attachments with or without powered functions are excluded, as well as hazards related to visibility and those related to the mobile elevating work platform applications to a front loader, because the front loader is not designed to lift and/or transport people. Front loaders with fully or partially self-evolving behaviour or logic and/or with varying levels of autonomy are also excluded.
Environmental aspects, other than noise, have not been considered in this document. Noise is not relevant for front loaders.
This document is not applicable to front loaders which are manufactured before the date of its publication as EN.

1.1 In Scope
The EN 9300-5xx series specifies the methods for long term archiving and retrieval of MBSE data represented as digital models. The characterization of models that are considered in scope of this document and the MBSE process use cases include:
- product or system design requirements models;
- functional architecture models;
- logical architecture models (system structure, arrangement, connectivity, software allocations and controls, and part relationships);
- numerically-based system analysis and simulation models, generally regulated 1D control loop models featuring system components and transport elements (tubing, piping, signalling, software);
- verification and validation of requirements;
- protocol dependent signal or communication networks;
- multi-model linking and system parametric models;
- system trade study models;
- the solution architecture models and data that are needed to implement the system and generate system engineering data for downstream designs.
1.2 Out of Scope
The EN 9300-5xx series does not address the original product model design process, or a specific configuration management process for the LOTAR archive. It does not address models depicting part specific technical data (physical materials or detail part standards). It is assumed that these archiving processes are within the scope of other parts of the EN 9300 series such as the 1xx series for CAD, the 2xx series for Product Data Management (PDM) data, or by applying existing alternative industry standards, or existing company business procedures.
Typical models and capabilities considered out of scope of this document include:
- physical spatial models or composite structures (as described by other LOTAR Parts);
- Finite Element and CFD models (as described by other LOTAR Parts);
- Product Data Management models (as described by other LOTAR Parts);
- electrical circuit boards, or physical wiring parts or systems (described by other LOTAR Parts or standards);
- the software development process and software models that are outside of the context of software parts, behaviours, or functions that represent software code within a model;
- how to preserve property and access rights, or government acquisition-regulatory controls;
- new standards, or major revisions to existing MBSE standards that were not available or applicable prior to the publication of this document.

The scope of the new standard will cover the different types of repair and rehabilitation that can be undertaken on / or with clay pipes. 
This will include details on trenchless installation technologies where clay pipes can be used for repair or replacement. The standard will outline the technique used and relevant standards that products can be used from as well as performance and testing criteria for products after installation. 
The scope will also cover repair and rehabilitation of pipes laid using the open trench installation method. This will include replacement of socketed joints and replacement or repair of pipes, junctions and manholes. The scope will again cover the products that can be used, their performance criteria and testing methods after installation.

This European Standard specifies a method for the determination of nitrogen in soil improvers and growing media. The Kjeldahl method determines ammonium-N, nitrate-N, nitrite-N and organic N content of soil improvers and growing media. Nitrogen in N-N-linkages, N-O-linkages and some heterocyclics (especially pyridine) is only partially determined. [6], [7], [8]
The method is not applicable to liming materials and preformed materials such as mineral wool slabs and foam slabs.
