1 ASTM Consensus Standards The Latest in Packaging Testing Presented by: Dhuanne Dodrill President Rollprint Packaging Products, Inc.

2 ASTM Overview Established in 1898 Voluntary, Full-Consensus Standards 141 Technical Committees 12,000 Standards Each standard is reviewed and balloted every five years

3 ASTM Overview ASTM Standards consist of: Test Methods Specifications Practices Guides Terminology

4 ASTM Overview Test Methods must have a precision and bias statement Subjected to properly conducted Inter-Laboratory Studies (ILS) that statistically determine repeatability and reproducibility and demonstrate that the test method can be validated Formal Process that requires: Accuracy Precision Repeatability (within lab precision) Reproducibility (between lab precision) Robustness or Ruggedness Range and/or Limit of Detection

5 ASTM Committee F02 F02: Flexible Barrier Packaging Focused on flexible barrier packaging including component barrier materials, their properties, and package design, development and production Flexible is defined as any package with at least one flexible component that can be bent or folded back upon itself Includes papers, nonwovens, plastic films, and metal foils, used alone, treated or in various combinations

6 ASTM Committee F02 6 subcommittees F02.10 Permeation F02.15 Chemical/Safety Properties F02.2 Physical Properties F02.40 Package Integrity F02.50 Package Design and Development F02.90 Executive

7 F88 Seal Strength Tensile type seal strength test Uses constant rate-of-jaw separation testing equipment Procedure 1 inch wide test specimens are cut Sealed area of the specimen is placed approximately equidistance between the grips Pulled apart with a grip separation rate of 8 to 12 inches/minute Report: Peak value and/or average value Mode of failure

8 F88 Seal Strength Testing Modes of Seal Failure

9 Interferences F88 Seal Strength Testing

10 F88 Seal Strength Testing Inter-Laboratory Study Involved 6 laboratories 14 models of test equipment from 8 manufactures Studied the effect of technique Crosshead speed Sample orientation Tail orientation or bending component effects

11 F88 Seal Strength Testing Crosshead speed no effect on results Evaluated in the range of 8 to 12 inches/minute

12 F88 Seal Strength Testing Sample orientation with respect to the moving crosshead has no effect on results

13 F88 Seal Strength Testing Tail orientation is important Impacts Seal Strength 90 lowest value 180 highest value Impacts Variation Unsupported least 180 most

14 Accelerated Aging and Climatic Stressing F1980 Accelerated Aging Guide Assumes the Arrhenius reaction rate function applies to the chemical reactions involved in the deterioration of materials Hold package at elevated temperature and set humidity Used for establishing expiry dates

15 Accelerated Aging and Climatic Stressing Proposed Standard on Climatic Stressing Geared towards products that are shipped next day or 2- day air Current standards result in excessive or severe climatic stressing and cause failures that would not occur in an overnight/2-day distribution environment ASTM D4332 ISO 2233 ISTA Simulation Tests (3A)

16 Accelerated Aging and Climatic Stressing Proposed Standard on Climatic Stressing Based upon: Information on shipping, handling, and storage environments Current industry practices Published studies Protocol Cold (-20 C at ambient humidity) for 4 hours Hot/Dry (50 C and 25%RH) for 4 hours Warm/Humid (30 C and 90% RH) for 4 hours Return test specimens to ambient for 24 hours between subjecting to subsequent climatic exposure

17 Integrity Testing Dye Penetration Proposed Standard for Detecting Leaks in Nonporous Packaging Dye penetrant solution based on surface tension: 25 dynes/cm or less Method A: evaluates seal integrity

18 Integrity Testing Dye Penetration Proposed Standard for Detecting Leaks in Nonporous Packaging Dye penetrant solution based on surface tension: 25 dynes/cm or less Method A: evaluates seal integrity Method B: evaluates sheet integrity

19 Integrity Testing F2227: CO 2 Tracer Gas F2338: Vacuum Decay F2391: Helium Tracer Gas Proposed: Pressure Decay Proposed: Airborne Ultrasound Proposed: O 2 Analysis Using Headspace Sampling

20 F2097 Design Guide Compendium of commonly used test methods and standards Organized into eight categories Safety Barrier Durability Package Integrity and Seal Strength Visibility and Appearance Processing Printed Ink Distribution

21 F2097 Design Guide Quick Reference Guide Summary of each referenced method Description Applicability How Used Compliance Testing Characterization & Evaluation

ASTM B117 Testing Quality Control

ASTM B117 Testing Quality Control ASTM B117 Testing, also known as a Standard Practice for Operating Salt Spray (Fog), is used to analyze relative corrosion for specimens of metals and coated metals exposed
