Review of Standards. To keep abreast of progress in industry, Joint Australian/ New Zealand Standards are subject to periodic review and are kept up to date by the issue of amendments or new editions as necessary. It is important therefore that Standards users ensure that they are in possession of the latest edition, and any amendments thereto. Full details of all Joint Standards and related publications will be found in the Standards Australia and Standards New Zealand Catalogue of Publications; this information is supplemented each month by the magazines ‘The Australian Standard’ and ‘Standards New Zealand’, which subscribing members receive, and which give details of new publications, new editions and amendments, and of withdrawn Standards. Suggestions for improvements to Joint Standards, addressed to the head office of either Standards Australia or Standards New Zealand, are welcomed. Notification of any inaccuracy or ambiguity found in a Joint Australian/New Zealand Standard should be made without delay in order that the matter may be investigated and appropriate action taken.

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.

The Standard includes construction, testing and labelling requirements. Faceguards complying with this Standard are not intended to protect wearers against a severe blow from a .
