This document specifies requirements and provides recommendations for the interpretation of observations to reach opinions that answer questions that are relevant for decision making in investigations or legal proceedings. This document states requirements that are applicable to all forensic disciplines. This document states requirements that apply when the opinion is based directly on human judgement and when the opinion is based on interpretation through a statistical model. This document is applicable to interpretation that occurs at a scene, within a facility, or within a judicial setting.
This document establishes requirements designed to safeguard the process for the interpretation of observations including the use of either statistical models or human judgement, to address alternative propositions based on the questions asked by the customer.
Interpretation is not necessary and the requirements of this document do not apply if the observations resulting from the analysis directly answer the relevant question.
EXAMPLE            In analytical chemistry, substances are often identified or classified. Provided that the applied analytical methods are not limited in selectivity or sensitivity for the given question, the observations can lead to a direct statement of the name of the substance (identification) or a type of material (classification). This is not considered interpretation for the purposes of this document.

This document specifies a real-time PCR procedure for the quantitation of the amount of roe deer DNA relative to total mammalian DNA in meat and meat products.

The content of roe deer can also be expressed as mass fraction in % using gravimetrically prepared calibration material from meat mixtures or model samples.
The method has been previously validated in a collaborative study and applied to DNA extracted from samples that consist of raw roe deer meat in a raw pig meat background as well as raw and boiled sausages.
The limit of detection of the roe deer PCR has been determined experimentally to be at least 5 target gene copies or at least 0,1 % roe deer.
The compliance assessment process is not part of this document.

Similarly, the interpretation of the obtained isotope delta values is not covered by this document. Following this protocol will result only in isotope delta values for the sample materials.
Solid and/or liquid sample materials can be analysed following this document.
Although other instrumental techniques can be applied to determine δ13C and/or δ15N values in food materials, these other techniques are not covered by this document.

Within the context of training data for Earth Observation (EO) Artificial Intelligence Machine Learning (AI/ML), this document specifies a conceptual model that:
—     establishes a UML model with a target of maximizing the interoperability and usability of EO imagery training data;
—     specifies different AI/ML tasks and labels in EO in terms of supervised learning, including scene level, object level and pixel level tasks;
—     describes the permanent identifier, version, licence, training data size, measurement or imagery used for annotation;
—     specifies a description of quality (e.g. training data errors, training data representativeness, quality measures) and provenance (e.g. agents who perform the labelling, labelling procedure).

This document specifies the dimensions, linear resistance, mechanical characteristics, construction and mass of conductors in aluminium or aluminium alloy for electrical cables for aerospace applications.
It applies to stranded conductors with nominal cross-sections of 5 mm2 to 115 mm2 inclusive.

NOTE         Clause A.2 contains guidance or rationale for this clause.
This document specifies requirements for small-bore connectors intended to be used for connections in neural applications.
This document does not specify requirements for the medical devices or accessories that use these connectors. Such requirements are given in particular standards for specific medical devices or accessories.

This document specifies methods to determine the durability of bondings, prepared by means of adhesive materials (e.g. adhesive tapes and adhesive masses), for the establishment of airtight layers under climatic conditions representative for indoor environments based on test methods with and without ageing.
The methods provided in this document require at least 120 days for aging and are therefore not suitable for a short time evaluation nor can they be applied to in-field testing. This document excludes test methods for external weathering or UV exposure, even though this might occur during the construction phase.
The following typical applications are distinguished:
-   bonding of the overlap of flexible airtightness layers;
-   bonding of flexible airtightness layers to construction products and penetrations;
-   establishment of airtightness layers by means of sheet materials and adhesive tapes.
This document does not apply to test methods for:
-   pre-compressed sealing tapes and sealing profiles which will be mechanically secured;
-   butyl-based adhesive tapes or adhesive masses;
-   sheet joints of wood-based panels or gypsum plasterboards with adhesive masses or filler systems;
-   bondings of bitumen membranes or of bitumen membranes to construction products;
-   bonding of self-adhesive membranes;
-   adhesive masses from reels. Adhesive masses from reels are cured viscoelastic adhesive masses, which are used in the same field of application as adhesive masses.
The tack is not addressed. It does not allow any conclusion on the durability of a bonding.
