ISBN 0 7337 1541 9 AS/NZS 4499.3:1997 2 PREFACE This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee CS/95, Helmets for Ball Games. This Standard deals with the requirements for faceguards intended to be used as an accessory to a cricket helmet, the requirements for which are set out in AS/NZS 4499.1, Protective headgear for cricket,Part1:Helmets. The Committee considers a faceguard to be a necessary component for improved head protection, however, the requirements have been dealt with in a separate Standard as faceguards are not usually attached permanently to helmets. Separating the requirements allows the user the choice of different styles of faceguards, or alternatively a temple protector, the requirements for which are set out in AS/NZS 4499.2, Protective headgear for cricket,Part2:Temple protectors . The ability of a faceguard to absorb some of the energy of an impact depends to a great degree on the geometry of the retention system of the helmet. In many cases, the retention system of a helmet has been designed to incorporate a chincup as a pivot point in the retention system, which acts to prevent the faceguard being pushed onto the wearers face. For some other types of helmets, the use of a chincup in place of an underjaw retaining strap could allow the helmet to be dislodged from the wearers head during an accident. Therefore, the use of a chincup is allowed within AS/NZS 4499.1, whereas the use of a chincup is not permitted within some other helmet Standards. In addition to providing protection for the face, the faceguard also provides protection for the temple region of the head which is an area where the skull is weak and contains easily ruptured blood vessels. The 400gn to 500gn initial deceleration figure cited in this Standard, measured using the test procedure and apparatus in AS/NZS 2512.3.2, Methods of testing protective helmets, Method 3.2: Determination of impact energy attenuation—Striker drop test, was selected because it discriminates between products which had been shown on the cricket field to provide adequate protection and products which had not performed well. It does not correlate with, and should not be confused with, similar figures used in other Standards to express expected brain deceleration. For a better understanding of the needs and requirements for head protection for cricketers, this Standard should be read and considered in conjunction with AS/NZS 4499, Parts 1 and 2. The term ‘informative’ has been used in this Standard to define the application of the appendix to which it applies. An ‘informative’ appendix is only for information and guidance.

  • Design of Neck Protection Guards for Cricket Helmets
    Design of Neck Protection Guards for Cricket Helmets T. Y. Pang a and P. Dabnichki School of Engineering, RMIT University, Bundoora Campus East, Bundoora VIC 3083, Australia Keywords: Cricket, Helmet, Neck, Guard, Design. Abstract: Cricket helmet safeguards have come under scrutiny due to the lack of protection at the basal skull and neck region, which resulted in the fatal injury of one Australian cricketer in 2014. Current cricket helmet design has a number of shortcomings, the major one being the lack of a neck guard. This paper introduces a novel neck protection guard that provides protection to a cricket helmet wearer’s head and neck, without restricting head movements and obstructing the airflow, but achieving a minimal weight. Adopting an engineering design approach, the concept was generated using computer aided design software. The design was performed through several iterative processes to achieve an optimal solution. A prototype was then created using rapid prototyping technology and tested experimentally to meet the objectives and design constraints. The experimental results showed that the novel neck protection guard reduced by more than 50% the head acceleration values in the drop test in accordance to Australian Standard AS/NZS 4499.1-3:1997 protective headgear for cricket. Further experimental and computer simulation analysis are recommended to select suitable materials for the neck guards with satisfactory levels of protection and impact-attenuation capabilities for users. 1 INTRODUCTION head and facial injuries (Ranson et al. 2013).

  • Armour & Weapons in the Middle Ages
    & I, Ube 1bome Hnttquarg Series ARMOUR AND WEAPONS IN THE MIDDLE AGES t Digitized by the Internet Archive in 2014 https://archive.org/details/armourweaponsinmashd PREFACE There are outward and visible signs that interest in armour and arms, so far from abating, is steadily growing. When- ever any examples of ancient military equipment appear n in sale-rooms a keen and eager throng of buyers invariably | assembles ; while one has only to note the earnest and ' critical visitors to museums at the present time, and to compare them with the apathetic onlookers of a few years J ago, to realize that the new generation has awakened to j j the lure of a fascinating study. Assuredly where once a single person evinced a taste for studying armour many | now are deeply interested. t The books dealing with the subject are unfortunately ' either obsolete, like the works of Meyrick, Planche, Fos- broke, Stothard, and others who flourished during the last L century, or, if recent, are beyond the means of many would-be students. My own book British and Foreign Arms and Armour is now out of print, while the monographs of I Charles ffoulkes, the Rev. Charles Boutell, and | Mr Mr Starkie Gardner are the only reasonably priced volumes j now obtainable. It seemed, therefore, desirable to issue a small handbook which, while not professing in the least to be comprehensive, would contain sufficient matter to give the young student, y the ' man in the street,' and the large and increasing number of persons who take an intelligent interest in the past just j that broad outline which would enable them to understand more exhaustive tomes upon armour and weapons, and 5 ARMOUR AND WEAPONS possibly also to satisfy those who merely wish to glean sufficient information to enable them to discern inac- curacies in brasses, effigies, etc., where the mind of the medieval workman—at all times a subject of the greatest interest—has led him to introduce features which were not in his originals, or details which he could not possibly have seen.

Having regard to the nature of the Museum (especially the vast field of Naval and Military History which it covers), the limited space, and the consequent necessity of having at times to' remove certain objects in order to exhibit others, it was found quite impos- sible to classify the numerous exhibits under groups or collections : but the index, which has been added, is of an exhaustive nature and will assist the Visitor in readily finding the objects of special interest. I would point out that the value of a work of this kind lies in its accuracy, and should any mistakes have crept into its pages in the course of compilation and printing, I hope they will be pointed out to me, that they may be rectified in future editions.
