NOTE Some components are dealt with in other parts of this standard.
This standard applies to legs, support rams and rams used at ambient temperatures from –10 °C to 60 °C.
This standard identifies and takes account of:
- Possible hazards which may be caused by the operation of legs, support rams and rams;
- Areas and operating conditions which may create such hazards;
- Hazardous situations which may cause injury or may be damaging to health.
This standard describes methods for the reduction of these hazards.
A list of hazards covered appears in clause 4.
This standard is applicable to all legs, support rams and rams placed on the market for the first time and which are manufactured after the date on which this standard was published.
This European standard does not establish the additional requirements for:
- Specially corrosive environments;
- Hazards occurring during construction, transportation, decommissioning;
- Earthquake.

Ta standard določa varnostne zahteve za stojke in potisne cilindre, ko se uporabljajo po navodilih proizvajalca ali pooblaščenega predstavnika. Primeri, ki jih zajema standard, vključujejo stojke, podporne potisne cilindre in potisne cilindre z mehanskimi podaljški, notranje ventile in varnostne pripomočke, tesnila, hidravlične priključke (do prve cevke ali ventila vrste B glej 3. del) in njihove dvižne točke, ne vključuje pa zaščitnih cevk in ovojev, zunanjih ventilov ter hidravličnih in elektrohidravličnih krmilnih sistemov. Ta standard velja za stojke, podporne potisne cilindre in potisne cilindre, ki se uporabljajo pri temperaturi okolja med -10 °C in 60 °C. Ta standard ugotavlja in upošteva: morebitne nevarnosti, ki jih lahko povzroči delovanje stojk, podpornih potisnih cilindrov in potisnih cilindrov; - področja in pogoje delovanja, ki lahko povzročijo takšne nevarnosti; - nevarne razmere, ki lahko povzročijo škodo ali škodujejo zdravju. Ta standard opisuje metode za zmanjševanje takšnih nevarnosti. Seznam zajetih nevarnosti se nahaja v Klavzuli 4. Ta standard velja za vse stojke, podporne potisne cilindre in potisne cilindre, ki so prvič dani v promet in so narejeni po datumu izdaje tega standarda. Ta evropski standard ne vzpostavlja dodatnih varnostnih zahtev za: - posebej korozivna okolja; - nevarnosti, ki se pojavljajo med konstrukcijo, prevozom, izločitvijo iz uporabe; - potres.
