Also, the valve shall be opened or closed by a sensing device. 7.3 Test method of the amount of water use Installation conditions The installation conditions for testing the amount of water use are as follows. a) Connect water pipe with the washing valve of urinal so that water can be supplied by the hydraulic pressure (dynamic pressure) of 0.1 MPa. In case that it is possible to the same result of the amount of water use, measurement may be conducted without connecting the urinal. b) Urinals that can adjust the amount of water use shall be adjusted to the mark location of the amount of water use which the applicant guarantees. However, if there is no mark or mark is not clear, adjust the location as maximum as possible. If there is no mark or mark is not clear, the product is not recognized as the same flushing valve of 7.1 General Test procedure The test procedure is as follows. a) Operate the action similar to urinating once, and measure the amount of water pouring from 6

13 the flushing valve by putting the water in a flow meter or an appropriate container. The test time of the amount of water use in a urinal that can automatically adjust the amount of water use based on the time of urinating shall be 20 seconds as a basis. b) Repeat a) for 5 times, and calculated the amount of water use to 0.1 L unit, except the biggest value and the smallest value. This represents the amount of water use of the urinal. In case that the amount if automatically adjusted based on the use interval, the interval between tests shall be maintained suitably. c) If the calculation result according to b) exceeds 2.0 L, it shall be considered not to comply with the criteria. In this case, further tests may not be conducted. 7.4 Method to measure the sensing distance General a) Confirm the materials suggested by the applicant on the user characteristic factors that may influence on the sensing distance before measurement. Example influence. In case of reflective sensing type, the contrast between black and white may have an b) Ambient temperature and humidity shall be based on general conditions in the laboratory, and water pipe may not be connected. c) The sensing device shall be installed in accordance with the method suggested by the applicant, and remain for sufficient time to be saturated to surrounding environment. If there is no objection to judgment, ambient temperature and humidity can be based on general conditions in the laboratory, and there is no need to connect the water pipe. Also, in case of installing the sensing device stored in the test conditions, additional maintenance time is not required. d) When a user moves from outside the sensing distance toward the urinal at about 50 cm/s, the shortest distance between the front side of the sensing device at the time when the sensing display device first operates and the user shall present the sensing distance. If there is no sensing display device, a method suggested by the applicant can be appropriately used. e) The use shall move along the straight line perpendicular to the approximate center of the front side of the urinal Range of sensing distance The range of sensing distance shall be measured as follows. a) Set the minimum sensing distance in accordance with the method suggested by the applicant, and check whether the sensing device detects a user from 20 cm away and operates the flushing valve normally. If it is different based on the user characteristics, the sensing device shall be taken from the shortest distance. b) After testing in accordance with a), set the maximum sensing distance in accordance with the method suggested by the applicant, and check whether the sensing device detects a user from 60 cm away and operates the flushing valve normally. If it is different based on 7

14 the user characteristics, the sensing device shall be taken from the longest distance Reproducibility of the sensing distance The reproducibility of the sensing distance shall be measured as follows. a) Set the sensing distance between 30 cm and 50 cm randomly, and measure the sensing distance according to the movement of the user. The user characteristics shall be maintained constantly. b) Present the difference between the maximum and the minimum among results of 5 times of measurement as the reproducibility Change in the sensing distance Change in the sensing distance shall be measured as follows. a) Measure the sensing distance for 3 times each under the user characteristics which make the sensing distance the most and the least under the same conditions as in b) Present the difference between the most and the least conditions as change in the sensing distance. 8 Reasons for Certification Category Improvement of resource circulation a Energy saving b Reduction of global environmental pollution c Degree h Reduction of local environmental pollution d Reduction of harmful substances e Reduction of life environmental pollution f Reduction of noise and vibration g a b c d e f g h Resource saving, water saving, improvement of recyclability, recycling of effective resources, etc. Energy saving, use of renewable energy, etc. Reduction of greenhouse gas emission, reduction of ozone layer-depleting substance emission, etc. Reduction of air pollutants emission, reduction of water pollutants emission, reduction of soil pollutants emission, reduction of waste generation, improvement of biodegradation, etc. Reduction of the use of harmful substances, reduction of exposure to harmful substances for human body, etc. Reduction of indoor air pollutants emission, reduction of light pollution, etc. Low noise, reduction of vibration Only limited to products complying with 4.7 8

15 Annex A (normative) Method to evaluate odor of urinals by use of the urinal A.1 User s evaluation A.1.1 Summary This method is intended to evaluate odor of urinals where general users do not use water, by using a questionnaire with multiple items other than the purpose of evaluation for obscuring the evaluation purpose. A.1.2 General principles In order to minimize the effect of other factors other than the urinal to be evaluated on the result, the installation and maintenance conditions of relevant toilets shall comply with the following criteria. a) The user test must be conducted on more than two toilets. b) Urinals installed in the toilet must be composed of only urinals for testing. More than two urinals must be installed and used. c) Air freshener must not be used. d) The state of toilet use and hygiene management shall comply with the following criteria. However, if it is not possible to follow this principle, the certification deliberation committee shall determine the suitability. The environmental labeling certification authority must report the state of toilet use and hygiene management to the certification deliberation committee after conducting the user test through onsite confirmation. 1) The use frequency per 1 urinal shall be average 12 times per day. 2) Indoor environment shall be designed according to conditions for temperature, humidity and ventilation as shown in the Table A.1. However, the test can be conducted by selecting a day with similar conditions with the design conditions in the Table A.1, and the testing conditions are recorded in the testing results.
