1.1 This specification covers factory-made propylene and polypropylene (PP) plastic-lined ferrous metal pipe and fittings, primarily intended for conveying corrosive liquids and gases. Requirements for materials, workmanship, dimensions, design, construction, working pressures and temperatures, test methods, and markings are included. Note 1-In this specification, propylene plastics cover those materials defined as both polypropylene plastics and propylene plastics in Definitions D883. Both materials are identified as "PP" on the product. Note that this is at variance with Abbreviations D1600, where PP is the abbreviation for polypropylene. Note 2-This specification does not include products coated with PP nor does it define the suitability of PP-lined components in chemical environments. 1.2 The ferrous piping products shall meet the requirements of the relevant specifications listed in 1.2.1. Nominal sizes from 1/2 through 12 in. in Class 125, 150, and 300-psi are covered. Note 3-The PP sealing faces may prevent achievement of the full pressure rating of the ferrous housings. For pressure limitations, the manufacturer should be consulted. Note 4-Flanged fittings are not available in sizes 1/2 and 3/4. 1.2.1 For Ferrous Pipe: ASTM Title of Specification Designation Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and A 53 Seamless (Types E and S) Seamless Carbon Steel Pipe for High-Temperature Service A 106 Electric-Resistance Welded Steel Pipe A 135 Electric-Welded Low-Carbon Steel Pipe for the Chemical A 587 Industry Seamless and Welded Austenitic Stainless Steel Pipe A 312 Electric-Resistance Welded Carbon and Alloy Steel Mechanical A 513 Tubing :et 1.2.2 For Ferrous Flanges: :bt ASTM Title of Specification Designation Gray Iron Castings A 48 Forgings, Carbon Steel, for Piping Components A 105 Gray Iron Castings for Valves, Flanges, and Pipe Fittings A 126 Forgings, Carbon Steel, for General-Purpose Piping A 181 Forged or Rolled Alloy-Steel Pipe Flanges, Forged Fittings, A 182 and Valves and Parts for High-Temperature Service Carbon-Steel Castings Suitable for Fusion Welding for High- A 216 Temperature Service (Grade WCB).

4.1 The extensive porosity present in pressed and sintered ferrous materials masks the effect of inclusions on mechanical properties. In contrast, the properties of material powder forged to near full density are strongly influenced by the composition, size, size distribution, and location of nonmetallic inclusions.4.2 The test for nonmetallic inclusions in powder forged steels is useful as the following:4.2.1 Characteristic to classify or differentiate one grade of powder from another.4.2.2 Means of quality comparison of powders intended for powder forging, lot to lot.4.3 Significant variations in nonmetallic inclusion content will occur if:4.3.1 The powder used to form the test specimen does not meet powder forging quality standards for nonmetallic inclusion content.4.3.2 Processing of the powder forged test specimen has been carried out under conditions that do not permit oxide reduction or allow oxidation of the test specimen, or both.1.1 This test method covers a metallographic method for determining the nonmetallic inclusion level of ferrous powders intended for powder forging (PF) applications.1.2 The test method covers repress powder forged test specimens in which there has been minimal lateral material flow (< 1 %). The core region of the powder forged test specimen shall contain no porosity detectable at 100×.1.3 This test method is not suitable for determining the nonmetallic inclusion level of powder forged test specimens that have been forged such that the core region contains porosity. At the magnification used for this test method, residual porosity is hard to distinguish from oxide inclusions. Too much residual porosity makes a meaningful assessment of the inclusion population impossible.1.4 The test method may be applied to materials that contain manganese sulfide (admixed or prealloyed), provided the near neighbor separation distance is changed from 30 μm to 15 μm.NOTE 1: The test method may be applied to powder forged parts where there has been a greater amount of material flow provided:The near neighbor separation distance is changed, orThe inclusion sizes agreed between the parties are adjusted for the amount of material flow.1.5 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This 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.
