If a child inhales a pen cap it might become lodged below the larynx and block the trachea. The risk of
asphyxiation can be reduced if the pen cap is ventilated or too large to enter the airway. Children must
be actively discouraged from sucking, chewing or putting pen caps in their mouths. A way of avoiding
the risk of inhalation of caps of writing and marking instruments is to manufacture products without
caps whenever possible. However, if caps are essential, the provisions of this document minimize risk
by specifying the design and performance of ventilated caps, which reduce the likelihood of inhalation
and delay asphyxiation pending medical intervention.
ISO/TC 10 recognizes that while it is possible to identify the age range of the children who are most
at risk, it is not possible to identify with certainty any writing instruments with detachable caps that
would never be accessible to children and hence never pose a risk. It is, however, acknowledged that
certain products (i.e. writing and marking instruments which are designed or only intended for use by
adults, e.g. jewellery pens, expensive fountain pens, professional technical pens)

Information technology -- Top-level ontologies (TLO)
This document specifies required characteristics of a domain-neutral top-level ontology (TLO) that can be used in tandem with domain ontologies at lower levels to support data exchange, retrieval, discovery, integration and analysis. If an ontology is to provide the overarching ontology content that will promote interoperability of domain ontologies and thereby support the design and use of purpose-built ontology suites, then it needs to satisfy certain requirements. This document specifies these requirements. It also supports a variety of other goals related to the achievement of semantic interoperability, for example, as concerns legacy ontologies developed using heterogeneous upper-level categories, where a coherently designed TLO can provide a target for coordinated re-engineering. This document specifies the characteristics an ontology needs to possess to support the goals of exchange, retrieval, discovery, integration and analysis of data by computer systems. The following are within the scope of this document —   Specification of the requirements an ontology needs to satisfy if it is to serve as a top-level hub ontology. —   Specification of the relations between a top-level ontology and domain ontologies. —   Specification of the role played by the terms in a top-level ontology in the formulation of definitions and axioms in ontologies at lower levels. The following are outside the scope of this document: —   Specification of ontology languages, including the languages OWL 2 and CL, used in ontology development with standard model-theoretic semantics. —   Specification of methods for reasoning with ontologies. —   Specification of translators between notations of ontologies developed in different ontology languages. —   Specification of rules governing the use of IRIs as permanent identifiers for ontology terms. —   Specification of the principles of ontology maintenance and versioning. —   Specification of how ontologies can be used in the tagging or annotation of data.

Guidelines for the validation of qualitative screening methods for the detection of residues of veterinary drugs in milk and milk products
This document describes general workflows and protocols for the validation and the verification of qualitative screening tests for the detection of residues of veterinary drugs in liquid milk (raw, pasteurized, UHT and reconstituted milk powders and whey protein extracts) including biological methods. This guideline does not cover the validation of residue analysis by HPLC, UHPLC or LC-MS/MS. This document is intended to be useful for manufacturers of screening test kits, laboratories validating screening methods or tests, competent authorities and dairies or end users of reagents or tests for the detection of veterinary drug residues in milk products. This document facilitates and improves the validation and verification of screening methods. The goals of this document are a harmonization in validation of methods or test kits in order for all stakeholders to have full trust in the result of residue screening and to limit the overlap and multiplication of validation work in different laboratories by sharing the validation results generated by an independent laboratory. Furthermore, a harmonized validation and verification procedure allows for comparison of the performance of different screening methods. This document does not imply that all end users are bound to perform all verification work proposed. The verification of the correct use of reagents/kits for the detection of antimicrobials is not part of the scope of this document.
