References Central distribution: Armed Forces' Publications and forms stores (FBF) Print: Elanders Fälth & Hässler, June 2013 READERS' GUIDE H VAS can be read a first time in its entirety and it can then act as a reference guide and as a checklist. This manual comprises both descriptive and requirement-based chapters as described below. Chapter 1, ‘Introduction’ describes the background, precondi- tions and objectives of the manual. Chapter 2, ‘Safety activities and requirements common to all materiel’ specifies weapon and ammunition related safety activities and how they can be conducted in the most suitable manner. Chapter 3, ‘Weapons’ specifies equipment related requirements for weapons of which the main sections are Common requirements and System requirements. Chapter 4, ‘Ammunition’ specifies equipment related requirements for ammunition. With regard to ammunition the specific subsystem requirements also apply. These are specified under the respective headings Warheads, Propulsion systems, Fuzing systems and Packaging. Chapter 5, ‘Summary’ of all of the manual’s requirements. Used as a checklist, e.g. when presenting a system to advisory groups. Appendix 1, ‘Definitions’ defines specific terms. Appendix 2, ‘Acronyms’ lists a key to the abbreviations and acronyms used in the manual. Appendix 3, ‘Standards’ relates to relevant standards known at the time of the publication of the manual. Appendix 4, ‘References’ provides references to literature relating to defence materiel. For some systems it may be difficult to determine where the boundary is between weapons and ammunition. In such cases it is essential that both chapter 3, Weapons and chapter 4, Ammu- nition are applied. H VAS E 2012 3 Readers' guide The Weapons and Ammunition Safety Manual (H VAS E) is based on - and is a complement to - the System Safety Manual (H SystSäk E). Both manuals are co-ordinated and are designed to be used together. H VAS E can however be read and applied independently. IMPROVEMENT SUGGESTIONS Comments and suggestions for improvements to H VAS E should be sent to FMV, 115 88 Stockholm. 4 H VAS E 2012 Readers' guide
