13、his European Standard has been drawn up by CEN/TC 15, Inland navigation vessels, whose secretariat is held by the German Institute for Standardization (DIN).

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 1994, and conflicting national standards shall be withdrawn at the latest by May 1994. In acc
15、ordance with the CENKENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

17、rmative) Mast lower part CEN EN*929 93 34045B OOZOLY bY1 = Introduction Since push barges do not generally have their own masts fitted with the lights required for push-tows, the masts are carried on the push vessel and fitted to the barges when the vessels are connected. Therefore, the mounting att
18、achments should be of a uniform type, have the same dimensions and fit the lower part of the mast so that work may be carried out quickly, easily and safely even in bad visibility conditions and in each weather situation. In addition, the mounting attachments ensure that the masts, and therefore the
19、 push-tow light, are correctly seated which is of fundamental importance for safety in shipping traffic. 1 Scope This standard applies to mounting attachments for demountable masts with an integral mast lower part for the placing of light on push barges. It specifies construction, dimensions, manufa
20、cture, arrangement and means of attachment. 2 Normative references This European Standard 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 hereafter. For dated re
21、ferences, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. IS0 2768-1 General tolerances - lerances for linear an

23、 Standard, the following definitions apply: 3.1 Mounting attachent A device comprising a mast stand and mast clamp which are arranged on the barge in such a way that they can maintain a signal mast in the specified position. 3.2 Mast stand A device fixed to the deck which accepts the lower part of t
24、he signal mast and secures it against rotation about the vertical mast axis. 3.3 Mast clamp A device which secures the top of the lower portion of the signal mast. 3.4 Mast lower part The lower part of the signal mast which is inserted into the mounting attachment. 4 Technical requirements Dimension
25、s in millimetres. General tolerances: IS0 2768-c. The requirements relate to construction, dimensions, design, arrangement and means of attachment. 4.1 Dimensions The mounting attachment is not expected to conform to the design illustrated here; compliance is only required in the case of the dimensi
26、ons specified. 4.2 Mast stand Smooth edges 4.3 Mast clamp The clamp is shown to be attached using screws and nuts/wing nuts. Any equivalent means of attachment is permitted provided that the mast is held securely. Only captive screws, nuts or wing nuts shall be delivery conditions used. CEN EN*727 9
27、3 m 3404589 0072015 588 = fige 4 EN 929: 1993 4.4 Mounting attachment The mounting attachment consists of the mast stand and a mast clamp. The mast stand shall be positioned so that the signal mast bearing pins are precisely aligned parallel to the longitudinal and transverse axes of the vessel. In
28、addition, the mast stand and mast clamp shall be arranged in such a way that the axis of the lower part of the signal mast is perpendicular to the design waterline plane. The arrangement illustrated in figure 3 is an example of this. 4.5 Mounting attachment arrangement on the push barge The mounting
29、 attachments shall be arranged on the push barge as shown in figure 4. The mounting attachments fitted to the vessel sides shall be arranged so that the masts may be mounted parallel to the longitudinal vertical plane of the vessel. For safety reasons, they shall not be positioned within the clear w
30、idth of the walkway and shall be arranged to ensure an easy mounting of the mast. The attachments fitted in the centre of the vessel may be rotated by 90 (e.g. in restricted conditions) so that the masts may be mounted parallel to the transverse vertical plane of the vessel. 4.6 Mast Only the dimens
31、ions of the lower end of the mast (mast lower part) are specified in annex A. The upper part of the mast, its height, the navigation light arrangement and other characteristics are not covered by this standard. They are governed by the shipping regulations of the corresponding navigation zone. 5 Mat
32、erial Weldable steel as specified in EN 10025. The screws, nuts or bolts used for the clamp shall be made of stainless steel or other non-corrodible materials. 6 Testing For the purposes of this standard, test the technical requirements as specified in this standard by visual examination and measure
33、ment. 7 Designation A mounting attachment for demountable signal masts comprising mast stand (figure 1) and mast clamp (figure 2) shall have the following designation: Mounting attachment EN 929 CEN EN*929 93 = 3404589 0092036 414 Page 5 EN 929 : 1993 l- cc- 281, 160 b Figure 1.
