--- Added "terms and definitions, symbols, abbreviations" (Chapter 3 of this section);

--- Added "mixed ingredients of the formula or production process changes, should be provided in accordance with this section new certificate of competency" requirements (This section 4.1);

--- Modify the grading and naming of polyethylene compound ingredients, delete PE63 material classification and naming, add "mixed the long-term hydrostatic strength curve at 80 °C does not allow inflection point before 5000h (t < 5000h) (part 4.3);

--- Deleted the design stress of PE63 material (part 4.4);

--- Modification of the properties of polyethylene compounds to be measured in the form of pellets and pipe in the determination of two parts, of which the granular material Determination of the mixed ingredients increased performance density, volatile content, moisture content, carbon black dispersion/pigment dispersion, the appearance of grade, gray Points, tensile nominal strain and yield stress requirements; measured in the form of pipe mixed material properties for the new requirements added, increased Requirements for butt fusion - bonding tensile strength, weatherability, resistance to rapid crack propagation (S4) and resistance to slow crack growth (part 4.5);

--- Polyethylene mixed material oxidation induction time of the test parameters and requirements from "200 °C, >= 20min" to "210 °C, >=20min "(part 4.5);

--- Increasing the "black mixture of carbon black in the average (initial) particle size range of 10nm ~ 25nm" requirements (Section 4.5);

--- Added "welding compatibility of polyethylene compounds" requirements (Section 4.6);

--- Added "health requirements" (Chapter 5 of this section);

--- Increasing the informative appendix "This part of ISO 4427-1.:2007 compared to the structural changes" (Appendix A of this section);

--- Increasing the informative appendix "This part and ISO 4427-1.:2007 technical differences and their causes" (Part B of this Appendix);

--- Polyethylene pipe system temperature stress reduction factor adjusted to Appendix C, an increase of 25 °C and 35 °C pressure reduction system and "When the temperature is less than 20 °C, the pressure reduction factor fT is 1.0" requirements (Appendix C of this section);

--- Increasing the informative appendix "mixed ingredients change" (Part D of this section);

--- Added a normative appendix "Determination of volatile content" (Appendix E of this section);

--- Added a normative appendix "weatherability" (Appendix F of this section).

This section uses the redrafted law to amend the use of ISO 4427-1.:2007 "plastic pipe system for water supply polyethylene (PE) pipe and pipe Part 1. General Principles.

This part of ISO 4427-1.:2007 compared to the structural adjustment. Appendix A lists the clauses and sections of this section ISO 4427-1.:2007 reg number control list.

This section compared with ISO 4427-1.:2007 there are technical differences. Relevant differences have been incorporated into the text and in the terms that they cover the margins are marked with a vertical single line (|). A list of these technical differences and their causes is given in Appendix B.
