13、ation and storage Introduction This Japanese Industrial Standard has been prepared based on the first edition of IS0 6749 Earth-moving machinery-Preservation and storage pub- lished in 1984 without modifying the technical contents. 1 Scope This Standard specifies the general methods for preservation
14、 and removal of preservation materials from earth-moving machinery and its elements, and the categories of storage and transportation conditions. NOTE : The International Standard corresponding to this Standard is as fol- lows. In addition, symbols which denote the degree of correspondence in the co
15、ntents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21. IS0 6749 : 1984 Earth-moving machinery-Preservation and storage (IDTI 2 Field of application This Standard is applicable to newly-manufactured earth
16、- moving machines as well as to those already in use to be preserved. 3 Definitions For the purpose of this Standard, the following definitions apply: 3 . 1 preservation Set of operations to be carried out by the manufacturer, the user and others for the purpose of protecting a machine against the c

21、he manufacturer. 4.1.3 All materials used for the preservation of a machine and its elements shall conform to the specifications laid down in Standards or other appropriate technical documents specified in the order or contract of sale, and shall ensure conservation of a machine for the intended per
22、iod of preservation. 4.1.4 A machine shall be delivered for preservation treatment without any traces of corrosion on metal surfaces, or damage to paintwork, metallic, or other coatings. A used machine shall be reconditioned prior to preservation. 4.1.5 Preservation treatment shall be carried out in
23、 suitable conditions (ambient temperature, humidity) and with the correct materials which provide for the required quality of preservation while taking due care to ensure the safety of personnel and protection of the environment. 4.1.6 Each machine given the preservation treatment shall be provided
24、with instruc- tions for the removal of preservatives. These instructions may be included as a separate chapter in the operators manual. 4.1.7 The instructions for preservation and removal of preservatives shall be packed in a labelled waterproof envelope and attached to the machine in a conspicuous
25、place. 4.1.8 The instructions for removal of preservatives shall specify the categories of conditions for storage and transportation, the date of preservation, and the dura- tion of validity of preservation. The instructions shall also specify the methods for the removal of preservatives and reassem
26、bly of dismantled elements, a list of tools and appliances needed for these operations. 4.1.9 Operations of preservation and removal of preservatives shall be carried out with due regard for the general accident prevention measures specified, if necessary, by the national governing body having juris
27、diction. 4.1.10 Full details concerning preservation, packing and transportation shall be specified by the manufacturer in special instructions included with the machine documentation upon request, for example a) a method of lifting the machine for loading and/or unloading in order to keep preservat
28、ives intact; particular requirements, such as operations necessary when a machine is to be transferred from one mode of transportation to another which may require un- packing, including a procedure for re-preservation. b) 4.1.11 It is important to ensure that tyres, hoses, etc. are protected agains
29、t dam- age or deterioration by preservatives, by solvents used near them, and by exposure to the sun, moisture and other natural occurrences.
