Isiqondwa kanjani isigaba sesibili SESINGENISO

Isigaba sesibili sesingeniso singezansi:
Lesi sigaba sigcizelela ukuthi izinga libuye libhekelele ukuvikelwa ezingozini, okuhlanganisa izingozi zikagesi, zemishini, ezishisayo, zomlilo kanye nemisebe, esimweni sokusetshenziswa okuvamile ngokuhambisana nemiyalelo yokusetshenziswa komkhiqizi, kanye nasendaweni izimo ezingavamile ezingase zilindelwe ngesikhathi sokusetshenziswa, futhi esimweni sokuphazamiseka kazibuthe kagesi okuthinta ukusebenza komshini. Ukusetshenziswa okuvamile lapha ngokuvamile kubhekisela ekusetshenzisweni ngokuhambisana nezidingo zemanyuwali, ukusetshenziswa okungavamile kwemishini yokupheka yasekhishini njengokusebenza okuchichimayo, njengegedlela likagesi emanzini ukwengeza ngaphezu kokuba amanzi eqile athinta ukuphepha kukagesi; ngaphezu kwezinto zikagesi ekuphazamisekeni kozibuthe, kungase kuqale noma kuvule ngokuzenzakalelayo umsebenzi oyingozi, okuholela engozini, njengegrinder yenyama kagesi ebanjwa ngesandla, lapho umsebenzisi ebambe isandla, kodwa engazange ayivule. umsebenzi, umsebenzisi uzokwazi ukuqala umsebenzi, kodwa umsebenzisi ngeke akwazi ukuqala umsebenzi. Ngenxa yokuphazamiseka kazibuthe, ikhanda eliziqalayo elizungezayo, kuzoba ukulimala komshini okuyingozi kakhulu. Kuyagcizelelwa futhi lapha ukuthi ukuvikelwa kwezingozi “kuyizinga elamukelekayo emhlabeni jikelele”; khona-ke kudingekile ukusho ukuthi imikhiqizo ehambisana naleli zinga ayiphephile ngokuphelele, futhi nokuphepha kwayo kuhlobene. Asikwazi ukubeka phambili izimfuneko ezithile ezingelona iqiniso ngenxa yokuphepha komkhiqizo. Liyini “izinga elamukelekayo emhlabeni wonke”? Ngokwabantu abavamile, kuyinkolelo evamile ukuthi umkhiqizo ungaqinisekisa ukuthi izinga elithile lokuphepha lanele, ukuthi leli zinga lokuphepha, empeleni, izinga lalezi zidingo lifinyelelwa, okungukuthi, ukufinyelela ” izinga elamukelekayo emhlabeni wonke”, phela leli zinga lizinga lamazwe ngamazwe. Sisebenzisa isibonelo esidlulele kancane ukuze sifanekise, insimbi, ngesikhathi sokusebenzisa umsebenzisi ingase ingazinzi ngenxa yokubamba, kusukela ezandleni zokuwa, ukuwa kungase kushaye unyawo, ukushaya unyawo kuwuhlobo lokulimala, kodwa empeleni, akudingekile ukuba sicabangele ukugwema lolu hlobo lokulimala, ngoba lolu hlobo lokulimala alulona “izinga elamukelekayo emhlabeni wonke”, ukugwema lolu hlobo lokulimala kudlula “izinga elamukelekayo emhlabeni jikelele”. Ukugwema ukulimala okunjalo kudlula “izinga elamukelekayo emhlabeni jikelele”. Kungaba okungenangqondo ukudinga insimbi ukuba iwe ezinyaweni zomuntu ngaphandle kokumlimaza. Ukwakhiwa kwamazinga nakho kudinga ukucabangela umsebenzi wangempela womkhiqizo, izindleko zokukhiqiza, izinga lenqubo yokukhiqiza, izinga lesayensi nobuchwepheshe, kanye nezinga lengqondo yomsebenzisi. Ngeke kube ngenxa yokuphepha, okwenza izindleko zemishini ziphezulu kakhulu, okuholela ekutheni abathengi bangakwazi ukukhokhela; noma ukubeka phambili kungenakwenzeka ukufeza izidingo zokuphepha; kungase kube ngenxa yokuphepha, umkhiqizo ulahlekelwa ingxenye yomsebenzi; noma umsebenzisi ngokwakhe ungumuntu ochwepheshe kakhulu, abadingi izinga eliphezulu lokuphepha, futhi kanjalo nokumosha izindleko.

This paragraph emphasizes that the standard also takes into account the protection against hazards, including electrical, mechanical, thermal, fire and radiation hazards, in the case of normal use in accordance with the manufacturer’s instructions for use, as well as in the case of abnormal conditions that may be expected in the course of use, and in the case of electromagnetic interference affecting the operation of the appliance. Normal use here usually refers to use in accordance with the requirements of the manual, abnormal use of the kitchen cooking appliances such as overflow operation, such as electric kettle in the water to add more than the excess water affects the electrical safety; in addition to appliances in the electromagnetic interference, it may be arbitrarily start or open the dangerous function, which leads to the danger of, such as hand-held electric meat grinder, when the user held in the hand, but did not turn on the function, the user will be able to start the function, but the user will not be able to start the function. Due to electromagnetic interference, self-started rotating head, will be very dangerous mechanical injury. It is also emphasized here that the hazard protection is an “internationally acceptable level”; then it is necessary to mention that products complying with this standard are not completely safe, and their safety is also relative. We cannot put forward some unrealistic requirements for the sake of product safety. What is “internationally acceptable level”? In layman’s terms, it is a common belief that the product can ensure a certain level of safety is enough, as to what extent this level of safety, in fact, is the standard of these requirements are met, that is, to achieve the “internationally acceptable level”, after all, this standard is an international standard. We use a slightly extreme example to illustrate, an iron, in the process of using the user may be unstable because of the grip, from the hands of the fall, the fall may hit the foot, hit the foot is a kind of injury, but in fact, we do not need to consider avoiding this kind of injury, because this kind of injury is not an “internationally acceptable level”, avoiding this kind of injury exceeds the “internationally acceptable level”. Avoidance of such injuries exceeds the “internationally acceptable level”. It would be unrealistic to require an iron to fall on a person’s feet without injuring them. The formulation of standards also needs to take into account the actual function of the product, the manufacturing cost, manufacturing process level, the level of science and technology, as well as the user’s cognitive level. Can not be for the sake of safety, making the cost of appliances is too high, resulting in consumers can not afford to spend; or put forward simply impossible to fulfill the safety requirements; may be for the sake of safety, the product loses part of the function; or the user itself is a very professional people, do not need such a high level of safety, and thus a waste of costs.
