29、onal Committees having a special interest therein are represented, express, as nearly as possible, an international consensus of opinion on the subjects dealt with. 2) They have the form of recommendations for international use and they are accepted by the National Committees in that sense. 3) In or

30、der to promote international unification, the IEC expresses the wish that all National Committees should adopt the text of the IEC recommendation for their national rules in so far as national con- ditions will permit. Any divergence between the IEC recommendation and the corresponding national rule

31、s should, as far as possible, be clearly indicated in the latter.

Scope 1.1 This report provides the general

46、principles of protection, by artificial ventilation, of analyzer(s) houses against the explosion hazards caused by internal release of flammable substances and, if applicable, against the hazards caused by an external explosive gas atmosphere. It also gives the conditions in which electrical apparat

47、us liable to cause ignition may be used in these analyzer(s) houses. These analyzer(s) houses may be situated in a hazardous area or in a non-hazardous area. 1.2 This report contains recommendations for the construction and Oper- ation of analyzer(s) houses, for their associated installations, such

48、as air ducts, and for the auxiliary devices necessary for providing and maintaining the conditions for ventilation and, when required, press u re. This report also specifies the verification and testing necessary to prove that the installation conforms to the above recommendations, and the markings

49、to be placed on such rooms or buildings. Notes 1.- In certain circumstances, the recommendations may be used for other buildings containing similar sources of release. 2.- This report does not deal with dangers associated with the toxicity of gases and vapours which may be dealt with by similar techniques.
