3、SI 03-1999 Foreword This Product Assessment Specification, PAS020, has been published to provide an interim specification in the absence of a dedicated British Standard. This Product Assessment Specification is not to be regarded as a British Standard. It will be withdrawn upon publication of its co

4、ntent in, or as, a British Standard. The Product Assessment Specification is based upon BS6800:1986 Specification for home and personal security devices. Specific technical requirements have been developed through consultation with a balance of interested organizations with regard to audible persona

5、l attack alarms. In preparing this specification, cognisance was given to the possible variety of shapes, sizes, methods of operation and power sourcing of such devices. Consequently, performance and information requirements were developed which could take account of various configurations without i

6、mposing undue restriction on the design freedom, so as to include products which perform their function and have user appeal. Acknowledgement is given to the following organizations who were consulted in the development of this specification: Besborough Marketing Bodyguard Security The British Retai

Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages1 to 4,

11、an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on theinside front cover.PAS020:1997 BSI 03-1999 1 1 Scope This Product Assessment Specification defines a minimum perfor

12、mance level for hand-held audible personal attack alarms intended for use by individuals who are mature, reasonably physically fit and are under threat of personal attack. This Product Assessment Specification applies to audible personal attack alarms which are capable of activation operation by one

13、 hand. NOTEAn audible personal attack alarm is, when operated, intended to startle and disorientate a would-be assailant and provide a distraction so that the user may make an escape. It is not intended to be used to provide a distress signal for attracting attention to a mishap. Although the signal

14、 may induce fear of detection and the intervention of others, this is an opportune secondary function. An audible personal attack alarm should not be expected to provide a complete safeguard against attack and users should always take suitable precautions to reduce the risk of attack. 2 Normative re

15、ferences This Product Assessment Specification incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed on the inside back cover. For dated references, only the edition c

16、ited applies; any subsequent amendments to or revisions of the cited publication apply to this Product Assessment Specification only when incorporated in the reference by amendment or revision. For undated references the latest edition of the cited publication applies, together with any amendments.

17、3 Definitions 3.1 audible personal attack alarm (APAA) device powered by gas or battery which, when activated by the user, emits an audible alarm 3.2 operated condition state of an APAA after activation which produces an audible alarm 3.3 activation specific action by the user to operate an APAA 3.4

18、 de-activation specific action which stops the operation of the audible alarm 4 Design 4.1 An APAA operating by the controlled release of a compressed propellant gas and incorporating metal or plastics aerosol dispensers shall conform to the performance requirements of BS3914 or BS5597 respectively.

19、 4.2 An APAA shall not emit toxic or irritant substances likely to cause injury. 4.3 Propellants used in aerosol devices shall not be flammable. NOTEThey should not be harmful to the environment. 4.4 The polarity of the battery shall be indicated within the battery compartment. 4.5 Any cord fitted t

20、o, or used to operate, the APAA shall: a) not be made from elasticated material; b) when measured, while applying a force of (4 0.5)N, have a length when extended of not more than 300mm; c) not contain any loop that fits over a 120mm diameter cylinder; d) have a “break link” to prevent its use as a

21、restraint by an assailant. 4.6 An APAA shall not imitate the shape of an offensive weapon. 4.7 An APAA shall be of a design which is comfortable and easy to hold securely, and which can be activated by one hand. 4.8 Devices activated by cord pulling shall also incorporate activation by pressing a bu

22、tton or similar. 4.9 Where there is dual means of activation, one means of activation shall be by one hand. 4.10 The means of activation shall be so positioned as to avoid accidental operation. 5 Performance 5.1 An APAA shall conform to the requirements of5.2 and5.3 after removal from each of the fo

23、llowing environments: a) dry heat (+ 50 2)C, for not less than 4 h; b) cold (0 2)C, for not less than 4h; c) damp heat (+ 40 2)C, 90% r.h.to 96% r.h., for not less than 4h. NOTE 1Separate samples can be used for each environment. NOTE 2It should be recognized that the performance of aerosol devices

24、may be adversely affected following prolonged exposure to low temperatures (seeclause7). 5.2 A device in the operated condition shall provide an arithmetical mean sound pressure level of not less than 90dB(A).PAS020:1997 2 BSI 03-1999 It shall be measured with a sound level meter conforming to BSEN6

25、0804 or BSEN60651 at30 intervals from15 to165, within a horizontal arc of radius 1m 20mm in front of the device when the device is mounted vertically on a solid surface. Its centre shall be at a height of 1.2m 20mm, in a free-field, under test conditions of (20 5)C and a wind speed of no more than 8

37、. Such a declaration is not to be confused with third party certification of conformity, which may also be desirable.PAS020:1997 BSI 03-1999 3 Annex A (informative) Recommended wording and advice for use in promotional literature A.1 The following wording, or equivalent, is recommended: “Use of an A

38、PAA should not be relied on as the sole means of preventing attack; it should be used in conjunction with precautionary measures that reduce the risks. Although many of us fear meeting a problem, the risks are very low. With forethought and informed judgement these risks can be reduced further”. A.2

39、 The following advice should be given: always carry the alarm ready for use; plan your route/journey; tell someone where you are going; use well lit roads avoid badly lit short-cuts, deserted stations, etc.; wear appropriate clothing; be alert. When using vehicles: always carry the alarm ready for u

40、se; park in well-lit areas; lock doors and close windows after entering vehicle; hide all bags or valuables; make sure the vehicle is roadworthy; have vehicle key ready on returning to vehicle; be alert.4 blankPAS020:1997 BSI 03-1999 List of references (see clause2) Normative references BSI publicat
