1 Introduction  to the Israeli Standard  
This Israeli Standard is the international Standard ISO 8770 (second edition) of November 2003, approved as 
an Israeli Standard with modifications and additions.  
 
The Hebrew text lists the following:  
- The Standards’ applicability with modifications and ad ditions  
- Details of the modifications and additions  to the international Standards’ sections  
 
The Hebrew part is followed by the International Standard verbatim  
 
This Standard is part of a series of Standards dealing with polyethylene pipes and fittings.  
The parts of the series are:  
SI 4476 part 1  - Polyethylene pipes and fittings: waste discharge systems (cold and hot) in buildings – 
requirements  
SI 4476 part 2  - Polyethylene pipes and fittings:  high -density polyethylene pipes in drain and drainspout  
systems – insta llation instructions  
 
The Standard’s applicability  (section 1 of the international Standard with modifications and additions)  
Note:  
The modifications and additions in this section are shown in a different font . 
This Standard  specifies requiremen ts for pipes, fittings and systems of pipes and fittings made of polyethylene 
possess ing 1 a solid  wall that serve for the discharge of waste  (cold and hot) within buildings.  
This Standard does not apply to underground piping, except for the section connec ting to the building’s 
sewer , to which this Standard applies . 
This Standard also specifies the parameters for the testing methods mentioned in this Standard.  
This Standard applies to PE pipes and to fittings and to their connectors, designed for the follow ing uses:  
a. Waste discharge piping for carrying domestic waste (cold and hot);  
b. Venting piping connected to a;  
c. Rainwater draining piping within the building.  
This Standard applies to  pipes and fittings designed  to be connected by means of elastomeric  sealing rings, 
tangent  welding or electric welding.  
                                                
1 Translator’s note: the Hebr ew is in the singular, implying that it’s the PE that has a solid wall, not the pipes etc.  SI 4476 part 1  (200 6)
