The Israeli Standard Institute together with the MNI instigated 4 new natural gas standards in mid 2009, based on the pressure of the gas. The four standards are: (1) 5664-1 Natural gas transmission / general; (2) 5664-2 natural gas transmission system / further needs for steel pipe (everything that is over 16 bar pressure comes under 5664-1 or 2). Both these standards stem from the Dutch standard NEN 3650-1 and 3650-2 with relevant changes and additions made for the Israeli market); (3) 5664-3 natural gas distribution system, adopted from the US standard ASME B 31.8 with relevant changes, and (4) 5664-4 natural gas supply system, which deals with matters up to the consumer’s meter, with relevant changes and was adopted from the US standard NFPA 54. Sections 3 and 4 were adopted from British documents with the objective to attain the highest possible level of safety and greater technical definitions based on Israeli laws
