Forged or Rolled 8 and 9 % Nickel Alloy

A522/A522M

  Steel Flanges, Fittings, Valves, and Parts

  for Low-Temperature Service

Forgings, Carbon and Alloy Steel, for Pipe Flanges,

A694/A694M

  Fittings, Valves, and Parts for High-Pressure
  Transmission Service

Flanges, Forged, Carbon and Alloy Steel for Low

A707/A707M

  Temperature Service

Forgings, Carbon Steel, for Piping Components with

A727/A727M

  Inherent Notch Toughness

Forgings, Titanium-Stabilized Carbon Steel, for

A836/A836M

  Glass-Lined Piping and Pressure Vessel Service

1.2In case of conflict between a requirement of the individual product specification and a requirement of this general requirement specification, the requirements of the individual product specification shall prevail over those of this specification.

1.3By mutual agreement between the purchaser and the supplier, additional requirements may be specified (see Section 4.1.2). The acceptance of any such additional requirements shall be dependent on negotiations with the supplier and must be included in the order as agreed upon between the purchaser and supplier.

1.4The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text and the tables, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply, unless the “M” designation (SI) of the product specification is specified in the order.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
