ISTA Standard 1G

Non-Simulation Integrity Performance Tests

About ISTA Standard 1G

ISTA 1G is for packaged-products 150 lb. (68 kg) or less, and challenges the strength and robustness of the product and package combination to withstand transport hazards.

ISTA procedure 1G is similar to ISTA 1A. The primary difference is that the vibration method used for ISTA 1G is random, whereas 1A vibraton is fixed.


Test Procedure 1G is broken down into two categories: Vibration and Shock
  • Vibration is random displacement that complies with ASTM D4728. Rotary or vertical linear motion of the platform is acceptable.
  • Shock testing is broken down into three test types: Drop, Incline-Impact (Conbur), and Horizontal Impact. Drop testing is a free fall test and complies with ASTM-D5276. Incline-Impact (Conbur) testing complies with ASTM-D880, and Horizontal Impact testing is in compliance with ASTM-D4003.


When properly applied, ISTA procedure 1G will provide tangible benefits of:

  • Shortened packaged development time and confidence in product launch
  • Protection of products and profits with reduced damage and product loss
  • Economically balanced distribution costs
  • Customer satisfaction and continued business
