EN 13317:2002+A1:2006 (E) 4 Introduction The manhole cover assembly, the subject of this standard, seals the manhole which gives access to the inside of the tank compartment for manufacturing, cleaning, and inspection, and forms an integr

23、al part of a loading, unloading or venting function. NOTE Cover plates used to seal manholes are not the subject of this standard. The manhole cover assembly, which comprises the manhole cover and gaskets and may include devices to secure it to the tank shell neckring, may also provide the mounting

24、points for equipment such as: fill hole cover; pressure limiting device(s); level detection equipment; vapour transfer valve; pressure and vacuum breather vent. EN 13317:2002+A1:2006 (E) 5 1 Scope This European Standard covers the manhole cover assembly and specifies the performance requirements, di

25、mensions and tests necessary to verify the compliance of the equipment to this standard. The equipment specified by this standard is suitable for use with liquid petroleum products and other dangerous substances of Class 3 of ADR - European Agreement concerning the International Carriage of Dangerou

26、s Goods by Road (flammable liquids) which have a vapour pressure not exceeding 110 kPa at 50 C including petrol, and which have no-sub-classification as toxic or corrosive. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. T

27、hese normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, 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 un

35、ssembly seals the manhole that gives access to the inside of the tank or compartment. The manhole cover assembly may provide aperture(s) to allow the installation of other equipment. 5 Design characteristics 5.1 Leak tightness 5.1.1 Pressure tightness When closed, the manhole cover assembly shall be

36、 designed to be vapour and liquid tight in any orientation, at any positive or negative pressure within the maximum allowable working pressure range of the tank compartment to which it shall be fitted. 5.1.2 Drop test Each type of manhole cover assembly shall be structurally capable of withstanding,

37、 without leakage or permanent deformation that would affect its structural integrity, a drop test as described in 6.3.3. 5.2 Temperature range Unless otherwise specified, the design temperature range shall be 20 C to 50 C. Where the manhole cover assembly is subjected to more severe conditions, the

38、design temperature range shall be extended to 40 C or +70 C as applicable. 5.3 Materials of construction !Metallic materials shall meet the requirements of EN 13094:2004, 5.2.“ The manufacturer shall provide with the equipment a full material specification for those parts that may come into contact

39、with the dangerous substances specified in the scope. EN 13317:2002+A1:2006 (E) 7 5.4 Dimensional characteristics The nominal diameter of the manhole shall be 500 mm. The critical dimensions for the mounting face attachment are specified in annex B. The height of any part of the manhole cover assemb

40、ly, including auxiliary equipment, must not exceed 150 mm above the mounting face. Examples of auxiliary equipment include: fill hole cover (in the closed position); pressure and vacuum breather vent; vapour transfer valve; emergency pressure relief valve (in open position); level detection equipmen

41、t. 5.5 Electrical resistance The electrical resistance between any conductive part of the manhole cover assembly which may come into contact with the dangerous substances and the manhole cover neckring shall not exceed 106. Provision shall be made for the bonding of the manhole cover neckring to the

42、 tank such that the electrical resistance between the two shall not exceed 10 . 6 Tests 6.1 General Two classes of tests are required, production tests and type tests. Testing methods and procedures shall comply with the requirements of !deleted text“ !EN 12266-1“ and EN 12266-2 except as specified

43、or amended within this standard. 6.2 Production tests 6.2.1 General The number, frequency and sampling methods of production test samples shall not be less than those specified within ISO 2859-1, (AQL of 2,5). Production tests shall comprise: seat tightness test (see A.4 of !deleted text“ !EN 12266-

46、.3.1 General A minimum of 2 production samples of each model type shall be type tested to demonstrate the performance and mechanical strength of the design. NOTE Devices having one design, size and set pressure are considered to be of one model type. Unless otherwise noted, all type tests shall be p

47、erformed at maximum and minimum design temperatures. Type tests shall comprise: seat tightness test; drop test. 6.3.2 Seat tightness test The seat tightness test shall be performed in accordance with the requirements of the production test with the following addition: test pressure: 200 kPa. 6.3.3 D

48、rop test The function of the drop test is to submit tank top equipment to the dynamic forces that can result if the tank rolls onto its side. The test shall be carried out only under ambient conditions. NOTE When testing assemblies that contain devices which are designed to vent at pressures less th
