  1. Selection List Standard Fields(Header Information) MTRL Code: 5 digit number assigned to a specific material Prefix: odd for metals, even for nonmetals Use Type: Functional or design “use” for material, i.e., adhesive, elastomer etc. Designation: Manufacturer’s nomencalture for test material Composition: Generic chemical makeup of material, i.e., epoxy, acrylic, etc. MAPTIS Presentation

  2. Selection List Standard Fields(Header Information, Continued) • Generic ID: Three alpha character pairs (6 characters) • 1st pair: Use Type • 2nd pair: Primary Composition • 3rd pair: Minor Composition • Min F (K): Minimum service/operating temperature from • manufacturer’s literature • Max F (K): Maximum service/operating temperature from • manufacturer’s literature • Specification: Designated when material is qualified to a • specification, can be multiple specs. MAPTIS Presentation

  3. Selection List Standard Fields(Test Data Information) • NHB/Type: Number for specific test per NASA-STD-6001 • 01 = Upward Propagation • 04 = Wire Insulation Flammability • 06 = Odor • 07 = Offgossging • 13 = Mechanical Impact • 17 = Promoted Combustion, etc. • Test NR: Distinct number assigned to each test series • - Prefix identifies test facility, e.g.M = MSFC, W = WSTF • Cure NR: Number that correlates with cure sequence • in cure table MAPTIS Presentation

  4. Selection List Standard Fields(Test Data Information, Continued) SMP NR Material Sample or specimen Number - 09 represents worst case record R: Rating assigned to each specific material test PCT OXY: Percent of oxygen in test chamber TEMP: Test temperature PRESS: Pressure in test chamber THK: Thickness of material test specimen Width: Width of test material sample Length: Length of test material sample MAPTIS Presentation

  5. Selection List Standard Fields(Test Data Information, Continued) Sample Wgt: Mass of material test specimen Class code: Material classification code: A = Material identification verified C = Material identification not verified Description: D = Descriptive information about material specimen Remark: R = Remark about test or configuration of specimen Temp: Temperature in test chamber MAPTIS Presentation

  6. Selection List Standard Fields(Test Data Information, Continued) Obsolete/Discontinued: Identifies material that are no longer produced by manufacturer Manufacturer/Supplier: The manufacturer and/or supplier of material Substrate Material: Identification ofMaterial used as a substrate, e.g., aluminum, fiberglass SUBSTR THK: Thickness of substrate material Other fields exist that are specific to each test type, i.e., flammability, offgassing, etc. MAPTIS Presentation

  7. Selection List Data Base Data Verification • Material Identification • Assign Material Code • Verify Manufacturer’s Designation • Verify Use Type • Verify Chemical Composition (Generic) • Minimum/Maximum Service Temperature • Establish Generic Identification Code • Specification(s) MAPTIS Presentation

  8. Selection List Data Base Data Verification • Manufacturer Identification • Verify Manufacturer, not Supplier • Address, Telephone and Facsimile Number • E-mail Address • New Test Data Temporarily Held in Preliminary Data Bases • Compare New Test Data with Historical Results • Research Anomalies in Test Results • Rating Criteria MAPTIS Presentation

  9. Selection List Data Base – Data Verification • Initial Data Review • Analyst Level • Engineer/Analyst Level • Final Review • NASA/NAS/CSC Team • Data Evaluated • Data Consistency Verified • Anomalies Resolved • Decision Made to Move Data to Selection List or to Hold MAPTIS Presentation

  10. Nonmetals Properties Data Base • Current Version • Source – Manufacturer’s Literature • Sparsely Populated • Separate Data Base • New Version • Source – Manufacturer’s Literature • 10 – 15 Major Properties • Selection List Data Base • Adhesives – 85% complete • Also Working Lubricants, Coatings, Plastics, Elastomers, Potting Compounds, Fabric, Tape, Film MAPTIS Presentation

  11. Metals Properties Data Base • Source Material • Mil-HDBK-5 • Aerospace Structural Metals Handbook • Alloys • Aluminum • Steel • Copper • Nickel/Cobalt • Titanium • Magnesium • Separate Data Base MAPTIS Presentation
