International Standards, Technical Specification, Publicly Available Specifications, Technical Reports or

structure and subdivisions. The section on drafting addresses normative elements such as title page,
introduction, scope, references, terms and definitions, and (optionally) requirements. Attention is paid to
proper drafting of requirements, if included. A clear distinction shall be made between requirements,
statements and recommendations. Definitions of requirements should also include (by definition or
reference) test methods for checking conformity to the requirements. The document also addresses proper
use of tables figures and mathematical formulae. Further sections address conformity assessment, quality
management and presentation. Annex D defines drafting and presentation of terms and definitions.
