11、ydrocarbons (alkanes), lacking significant amounts of aromatic hydrocarbons, and suitable for use in medicines or food. 1.2.2 Class 2 Circuit: The portion of the wiring system between the load side of a Class 2 power source and the connected equipment. A Class 2 power source is limited to 0 to 20 vo

14、tri dishes with sterile nutrient agar shall be distributed in 20 sampling pairs on the floor of a testing room. One of each of the pairs shall be uncovered and exposed to the air in the room for five minutes and then covered. Immediately following this, the un-exposed Petri dishes of each of the pai

15、rs shall be uncovered and then exposed to a blanket of fog from the generator being tested and used according to its user operating instructions that covers the floor of the room for 5 minutes. The fog shall be dense enough that some of the Petri dishes are obscured from view when viewed by a person

16、 at two meters distance with standard room illumination from above at a level of 300 to 400 lux. The dishes shall then be covered. All 40 Petri dishes shall be allowed to incubate at 20 degrees C for three days and then the Petri dishes shall be evaluated for bacteria and fungus growth. The Petri di

17、shes exposed to the fog shall not have significantly larger fungus or bacterial colonies than the Petri dishes not exposed to the fog. The null hypothesis shall be that there is no significant difference between the two means of the two sets of samples. The null hypothesis shall not be rejected if t

18、he mean for the fog exposed samples is below the mean for the non-fog exposed samples, or if the mean is higher but the probability of the difference being attributable to chance is above 0.9. The fog generator produces an aerosol that is acceptable if the null hypothesis is not rejected. 2.2.6.2.2

19、The test described in 2.2.6.2.1 shall be judged to be unnecessary and it shall be permissible to judge the aerosol reasonably free from being a vector for viable micro-organisms if (a) the water is heated to 80 degrees C or above and held at that temperature for at least 5 minutes or if it is heated

20、 to 70 degrees C or above and held for at least 30 minutes before fog is generated; (b) the user operating instructions cite the importance of this temperature and holding period and caution the user not to attempt to generate fog with water at a lower temperature or water that has not been held for

21、 the full length of time for that temperature; and (c) the fog generators user operating instructions state that only potable water shall be used in the fog generator. 2.2.6.3 Fog generators that use unheated water and no glycol, glycerin, or mineral oil The hygiene of the aerosols produced by fog g

22、enerators that produce fogs of water without heating the water shall be evaluated per clauses 2.2.6.3.1 and 2.2.6.3.2. 2.2.6.3.1 Forty covered Petri dishes with sterile nutrient agar shall be distributed in 20 sampling pairs on the floor of a testing room. One of each of the pairs shall be uncovered

23、 and exposed to the air in the room for five minutes and then covered. Immediately following this, the un-exposed Petri dishes of each of the pairs shall be uncovered and then exposed to a blanket of fog from the generator being tested and used according to its user operating instructions that cover

The fog shall be dense enough that it can be seen to be wafting over the Petri dishes when viewed by a person at two meters distance with standard room illumination from above at a level of 300 to 400 lux. The dishes shall then be covered. All 40 Petri dishes s

25、hall be allowed to incubate at 20 degrees C for three days and then the Petri dishes shall be evaluated for bacteria and fungus growth.

In addition, the user operating instructions must state these requirements that the water be potable and free of legionella pneumophila and that, if a hol

32、that are to be marked on the product, printed on an instruction sheet, or in some other way conveyed to the end-user or service person. Annex B gives French translations for these warning phrases. It shall be acceptable to present the warnings in other languages besides English and French if the int

33、ended audience does not read English or French, as long as the translations adequately convey the same information and sense of urgency and importance as the English warnings and cautions. 2.2.8 User operating instructions User operating instructions or user manuals shall be provided with the product and shall conform to the current edition of ANSI E1.14. It shall be acceptable to publish the user manual in a language in addition to English if the intended audience does not read English. That second language shall be the language of the intended audience. 2017 ESTA 8 F&S/2007-3004r5a
