The scope and rationale of this project are the following:
• Add requirement that the apparent ring tensile strength test be conducted at 73.4°F (23°C) only.
• Revised X1.1, X1.2 and X1.3 for clarity, fixing X1.3 which incorrectly states that the only SDR mentioned in Table 1 is SDR 9.
• Revise X3 to remove eight instances of mandatory language.
• Reduce frequency of recommended quick burst test at elevated temperatures in X3.
