This chapter provides specific guidance on the content of all IUCLID sections and subsections, which includes guidance on all data entry fields. The instructions on Endpoint study records of sections 4 to 10 are completely based on the help texts provided with the OECD Harmonised Templates (see chapter D.4.7.1 What is an Endpoint study record?).
All help texts are accessible as context-sensitive online Help by
selecting the Help button 
on the toolbar or pressing the F1 key on the keyboard
(see chapter A.3 Online Help).
Note
Section 0 Related information is actually not a data entry section, but gives an indication of all associations existing between a Substance dataset and Templates, Categories and Mixtures. In Substance datasets, the following subsections are provided:
Section 0.1 Templates: So-called Inherit Templates can be added to a dataset and are then indicated as links (i.e. Template datasets serving as containers for Endpoint records which are "inherited" to a dataset). In addition, Endpoint records can be copied from so-called Copy Templates. For detailed guidance, see chapter D.5 Template (Create and update Template related information).
Section 0.2 Categories: Links to all Categories are provided which the Substance dataset under consideration is related to as member of these chemical categories. For detailed guidance, see chapter D.6 Category (Create and update Category related information).
Section 0.3 Mixtures: Links to all Mixture datasets are provided which the Substance dataset under consideration is related to as a component.
In Mixture datasets, the following subsections are provided only:
Section 0.1 Templates: as above.
Section 0.4 Related Substances: Substance datasets related to the Mixture as components can be added and are then indicated as links. For detailed guidance, see chapter D.7 Mixture (Create and update mixture related information).
