The Military Handbook (1995) of the Netherlands states: “Displaying the white flag means that one wants to negotiate with the adverse party (for example about a cease-fire) or that one wants to surrender.” 
Netherlands, Handboek Militair, Ministerie van Defensie, 1995, p. 7-40; see also p. 7-37.
The Military Manual (2005) of the Netherlands states:
The white flag indicates that the party flying the flag wishes to parley. This party must cease firing. The bearer of the white flag, and those accompanying this person, have a right to physical inviolability. The receiving party need not cease fire over the whole sector. The white flag is also accepted as the customary indication of a wish to surrender.
