11、rsedes BS3066:1981 which is withdrawn. Matters concerning safety cannot be too strongly emphasized and it is a prime requirement that a safe tool should be offered to the user. Since publication of the original specification, the design of chisels and manufacturing techniques employed have continued

12、 to improve. It is not the intention of this standard to impose restrictions on the types of materials from which chisels may be manufactured, and so inhibit development in this direction, but greater importance is placed on tests and testing procedures. It should be recognized that cold chisels and

13、 allied tools are prone to work hardening and that the hardness values quoted in Table 13 to Table 15 apply only at the time of manufacture. In so far as the user is concerned, reports on accidents continue to indicate that such accidents occur as a result of abnormal usage and failure to maintain t

14、ools in a safe condition. A responsibility is therefore placed on the users, in their own interests, to ensure that their tools are properly maintained. A leaflet on safety recommendations is available from manufacturers. An extract is reproduced asAnnex A. Fitted hand guards are available on select

15、ed chisels and allied tools, as optional extras. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal oblig

16、ations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages1 to 18, 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 t

18、 bolsters; floorboard chisels; plugging chisels; concrete or moil points; parallel pin punches; taper punches (including nail and reaper punches); centre punches. 2 References 2.1 Normative references This British Standard incorporates, by dated or undated reference, provisions from other publicatio

19、ns. These normative references are made at the appropriate places in the text and the cited publications are listed on the inside back cover. For dated references, only the edition cited applies; any subsequent amendments to or revisions of the cited publication apply to this British Standard only w

20、hen incorporated in the reference by amendment or revision. For undated references, the latest edition of the cited publication applies, together with any amendments. 2.2 Informative references This British Standard refer to other publications that provide information or guidance. Editions of these

21、publications current at the time of issue of this standard are listed on the inside back cover, but reference should be made to the latest editions. 3 Material Chisels and allied tools shall be manufactured from carbon or alloy steels. Carbon steel tools shall be manufactured in accordance with the

22、requirements ofTable 1. In alloy steel tools, sulfur, phosphorus and residual elements shall comply with the requirements of BS970-2:1988, except that the main alloying element shall be not less than0.9%(m/m). Chisels and allied tools shall not be manufactured from free cutting or semi-free cutting

23、steel. Hand grips shall be manufactured from high impact plastics material, natural rubber 70 hardness or from other suitable material capable of meeting the requirements of clause8.

Round sections may be knurled if required. Head types shall be of those

25、 shown inFigure 1 toFigure 11. Tools of body section below13mm shall have chamfered type head. Tools of 13 mm body section and above shall have either a domed anti-mushroom type head or a conical head. The conical head dimensions shall be as stated inTable 2toTable 9andTable 11toTable 12. NOTEIt is

26、permissible for tools of 13 mm body section to have a chamfered head. Illustrations of typical hand guards are shown inFigure 12. 4.2 Dimensions 4.2.1 Dimensions, other than length, shall be in accordance with the Table 2toTable 12. Unless otherwise agreed between the purchaser and the manufacturer,

27、 lengths of chisels and allied tools shall be as stated inTable 2 toTable 12. Unless otherwise agreed between the purchaser and manufacturer, tolerances shall be in accordance with BS4114:1967. 4.2.2 The designating size of chisels and bolsters shall be the nominal width of the cutting edge, and len

28、gth where appropriate. 4.2.3 Concrete or moil points shall be designated by length and section (seeTable 9). 4.2.4 For oval section steels the body section dimensions referred to inTable 2 toTable 9 are major axis dimensions. The minor axis shall be not less than half the major axis. 4.2.5 Punches s

29、hall be designated by the point diameter. 4.2.6 Hand guards shall be so dimensioned that they are a tight fit on the tool shaft and provide protection to the users hand from misdirected hammer blows. They shall be designed to provide a comfortable grip. 5 Heat treatment and hardness 5.1 General Both

30、 plain carbon and alloy steel tools shall be through-hardened, followed by tempering or stress relieving, to achieve the hardness values given in Table 13 andTable 14 when tested in accordance with8.1. 5.2 Hardness zone at the cutting edge/tool points 5.2.1 Chisels and bolsters The tool blade shall

31、be heat treated to give readings within the hardness range specified inTable 13 over the appropriate minimum distance from the extreme cutting end as given inTable 15. 5.2.2 Concrete points The hardness zone for concrete or moil points shall be calculated on the body section (seeTable 9) substituted

32、 for the cutting edge size inTable 15. 5.2.3 Punches The blade shall be heat treated to give readings within the range specified inTable 14 and the hardened zone shall extend from the tool point (working end) to a minimum point5mm into the body section. 5.3 Hardness zone at the head 5.3.1 Chisels, b
