3、permitted without license from IHS -,-,- S 3033 : 1997 Foreword This translation has been made based on the original Japanese Industrial Standard established by the Minister of International Trade and Industry through deliberations at Japanese Industrial Standards Committee in accordance with the In
4、dustrial Standardization Law. Now that the environmental standard value of nitrogen oxides emission concentration comes to the difficult level to be achieved, the Environment Agency has started to lay down and instruct “The NOx reduction guiding principle“ and “The low NOx combustion appliance recog
5、nizing principle“ for the purpose of reducing NOx emitted from the facilities and appliances of small size not subjected to the restriction by the Air Pollution Control Law such as burning appliance for commercial service, household burning appliance, etc. in addition to the fixed origin of generati
6、on and mobile origin of generation restricted so far by the law. In the wake of this policy, for the household oil burning appliances, the autonomous criteria for nitrogen dioxide emission rate in the exhaust gas from open type forced ventilating oil burning space heater was determined in advance of
7、 other oil burning appliances to seek the reduction of nitrogen dioxide, and moreover in the aspect of air pollution, the reduction of NOx rate emitted not only in indoor but also in outdoor has been required, so that Japan Industrial Association of Gas and Kerosene Appliances set up the voluntary c
8、riteria for the nitrogen oxide emission rate with regard to NOx at a whole not limiting only to nitrogen dioxide. In addition, JIS S 3032 Measurement method of NOx emission rate for open type forced ventilating oil burning space heaters was developed in 1994 to establish the measurement method. The
9、development at this time was aiming at contributing to the guarantee of the safety of national lives and the preservation of environment by setting up the measurement method of nitrogen oxide emission rate for the open type natural ventilating oil burning space heaters popularized widely in their nu
10、mber of units following the open type forced ventilating oil burning space heaters.

14、7 Measurement method of NOx emission rate for open type natural ventilating oil burning space heaters Introduction This Japanese Industrial Standard is developed in order to establish the measurement method of NOx emission rate for open type natural ventilating oil burning space heaters for the purp
15、ose of seeking the reduction of NOx emission rate. 1 Scope This Japanese Industrial Standard specifies the measurement method of NOx emission rate emitted from the open type natural ventilating oil burning space heaters the fuel consumption(l) of which is 600 g/h or less (hereafter referred to as “s
16、pace heater“). Note (l) Fuel consumption is indicated with the maximum burning fuel rate per hour under the normal burning condition. This shall be a rate of the fuel burning in one heat chamber or nozzle. 2 Normative references The following standards contain provisions which, through reference in
17、this Standard, constitute provisions of this Standard. The most recent editions of the standards indicated below shall be applied.
