After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received

12、the approval of the National Associations and the Official Services of the member countries of ASD, prior to its presentation to CEN. 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 November 2008,

13、 and conflicting national standards shall be withdrawn at the latest by November 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights.

14、 According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,

15、 Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. BS EN 3016:20084 1 Scope This standard specifies the characteristics of heat resisting steel, countersunk, load spreading washers for use in a

16、erospace applications at temperatures not exceeding 650 C. They are intended primarily for use under the head of bolts with strength classification up to 1 250 MPa. They are used to provide sufficient bearing area to prevent indentation of parent metals with low compressive strength at operating tem

17、peratures, thus ensuring no relaxation in the bolt load occurs. 2 Normative references The following referenced documents are indispensable for the application of this document.
