31、han 25 percent of the inside diameter of four-sided cans or of the distance from the front to back (apex of triangle to center of base) of triangular cans. 4.5 A waste can, when the cover is closed, shall prevent continued combustion of the contents should ignition occur from any cause. Projections,

32、 ridges, or other obstructions that might interfere with the closing of the cover shall be eliminated. 4.6 A waste can cover may be opened by hand or by a foot-operated lever. 4.7 The cover shall close by gravity and shall be prevented from opening more than 60 degrees from the closed position. 4.8

33、The form of the can shall prevent any appreciable area of the side or rear wall from being in close proximity to a room wall. Waste cans with at sides or back or both shall be marked in accordance with 17.1B. Revised 4.8 effective April 4, 2016 4.9 The form and assembly of a waste can shall be such

34、that dripping of oil to the oor is prevented. 4.10 A waste can shall be provided with supports to space the bottom not less than 3 inches (76 mm) nor more than 4 inches (102 mm) above the oor and in a manner that will provide free circulation of air beneath the can. See Can Supports, Section 14. 4.1

35、1 A waste can shall be provided with handles to make it readily portable in an upright position. 4.12 Conventional designs of cans illustrating forms of construction that are in compliance with these requirements are illustrated in Figures 4.1, 4.2, and 4.3.

39、 be made of galvanized sheet steel, terne plate, or of corrosion resistant metal. Uncoated steel may be used if cans are galvanized after forming. 5.2 The minimum thickness of metal used for the body, bottom, and cover shall not be less than that specied in Table 5.1. In the case of coated sheets, t

40、he thickness shall be that measured under the coating.

42、the full piece as rolled. Thickness is to be determined on the sheet not less than 3/8 inch (9.5 mm) from a cut edge and not less than 3/4 inch (19.1 mm) from a mill edge. 5.4 A coating of galvanized sheet steel shall comply with the coating designation G60 or A60 in Table 1 of the Standard Specicat

43、ion for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot-Dip Process, ANSI/ASTM A653/A653M. Not less than 40 percent of the zinc shall be on either side, as determined by the single-spot test described in ANSI/ASTM A653/A653M. The coating shall be free from l

44、umps, blisters, dross, and ux, and shall not ake or peel when formed. 5.4 revised December 15, 2004 5.5 The weight of coating on terne-coated sheet steel shall be at least as specied for coating designation LT35 in Table 1 of the Standard Specication for Steel Sheet, Terne (Lead-Tin Alloy) Coated by

45、 the Hot-Dip Process, ASTM A308. That is, the triple-spot coating weight shall not be less than 0.35 ounce per square foot (0.107 kg/m 2 ) and the single-spot coating weight shall not be less than 0.25 ounce per square foot (0.076 kg/m 2 ). 5.5 revised December 15, 2004 5.5.1 The weight of a galvani

46、zed coating may be determined by any method. However, in case of question, coating weight shall be established in accordance with the Standard Test Method for Weight (Mass) of Coating on Iron and Steel Articles With Zinc or Zinc-Alloy Coatings, ASTM A90/A90M. 5.5.1 revised December 15, 2004 5.6 Meta
