Per i tubi flessibili assemblati con ambedue i raccordi del tipo di curve a 45°, 90° oppure raccordi ad occhio, è necessario indicare l’angolo<br />

relativo tra gli stessi, cioè l’orientamento da determinarsi come indicato nella figura. Mantenendo il tubo in posizione orrizzontale, partendo<br />

dall’occhio dell’osservatore disporre il raccordo più lontano in posizione verticale, misurando in senso orario, l’angolo compreso tra il<br />

raccordo più vicino e la verticale del raccordo opposto. Conforme a ISO 1436 - ISO 17165-1.<br />

For assembled hoses with both fittings type elbow 45°, 90° and banjo fittings, it’s necessary to state the relative angle between therm, this<br />

means the orientation to be estabilished as shown in the figure. Keep the hose in a horizontal position then, starting from the eye of the<br />

observer, place the furthest fitting in a vertical position and measure the angle between the nearest fitting and the vertical of the opposite<br />

one in a clockwise direction. In conformity with ISO 1436 - ISO 17165-1.<br />
