18、eliability of the boilers not included in the boilers and the small boilers specified in the Boiler and Pressure Vessel Safety Regulation (Labor Ministry Ordi- nance No. 33, September 1972) based on the Industrial Safety and Health Law (Law No. 57, 1972) and which are used for domestic hot-water sup
19、ply and heating, In this revision, the criteria for water quality was revised in order to correspond to the revised Ministry Ordinance related to Water Works Law, and “annex (norma- tive) Interim standard of JIS S 3021 Oil burning water boilers” was established as an interim measure. 1 This Japanese
20、 Industrial Standard specifies the oil burning water boil- ers (hereafter referred to as “boiler”) used for hot-water supply, heating, etc. which use kerosene, light oil or heavy oil as fuel, whose working pressure is 0.1 MPa or lower and heating surface area is 4 m2 or smaller. Scope 2 Normative re
21、ferences The standards listed in attached table 1 contain provi- sions which, through reference in this Standard, constitute provisions of this Standard. The most recent editions of the standards (including amendments) shall be applied. 3 Classification 3.1 Classification according to burning system
22、s The classification of boilers according to burning systems shall be “pot type”, “pressure spray type”, “rotary va- porization type” and “carburetion type” specified in 4 . 1 of JIS S 3030. 3 . 2 The classification of boilers ac- cording to draft systems shall be as specified in 4 . 2 of JIS S 3030

35、 Ignition is easy and the use of dangerous materials of high inflammability such as alcohol or dangerous operation are unnecessary. Operation at each part is smooth and correct without any harmful deficiency in its use. Knobs, etc. shall not easily deform during use and shall be free from any ab- no
36、rmality in operation. When the temperature rises abnormally as a result of abnormal combustion, the combustion of burner stops automatically. Operation is easy and not likely to result in danger. Operation of flame extinction is done easily and securely. With regard to the boiler with peephole, it d
37、oes not come to a condition impos- sible to confirm a state of combustion as a result of adherence of lamp black on the peephole during the combustion in a normal handling. Boiler equipped with combustion controller is, at each combustion rate, unlikely to generate abnormally large flame, produce se
