Consistency is the key to accurate and repeatable test results. Variations in the test setup, test procedure, environmental conditions, and operator input can all affect the test results.
• Make sure that the appropriate gauge length, test speed, type and capacity of load cell, and grip and grip jaw selection are appropriate.
• Insert the specimen in the grips correctly and clamp it securely. Manual wedge grips are difficult to tighten consistently even with the same operator. You can minimize this variation by using pneumatic grips that always grip at the same pressure.
• Control the temperature and humidity to standard laboratory conditions or record the actual conditions when a test is performed.
• Ensure that your testing system and accessories are regularly serviced and calibrated to keep them at the peak of efficiency.
