Achieving optimal test results with your ISO 17707 Shoe Flexural Stiffness Tester from Gester Instruments requires a thorough understanding of the tester and adherence to best practices. This guide will walk you through the essential steps to ensure accurate and repeatable results.

Introduction

The ISO 17707 standard is an internationally recognized specification that outlines the methods for measuring shoe flexural stiffness. This standard is crucial for assessing the durability and comfort of footwear, making it a vital metric for manufacturers, researchers, and quality assurance professionals. Gester Instruments is known for providing reliable testing equipment and procedures that help ensure compliance with these standards.

Understanding ISO 17707 Standards

Brief Overview of ISO 17707

ISO 17707 specifies the methods for measuring flexural stiffness of footwear, which is a critical measure of a shoe's ability to withstand repeated bending without deforming excessively. This standard covers the testing procedures and parameters that ensure consistent and comparable results across different laboratories and testing facilities.

Significance of Adhering to Standards

Adhering to ISO 17707 standards is essential for ensuring that your test results are reliable and comparable to those obtained by other laboratories. This consistency is particularly important when conducting international comparisons or when benchmarking against industry standards.

Setting Up the Gester Flex Tester

Setup Process

The initial step in testing is to properly set up the ISO 17707 Shoe Flexural Stiffness Tester. Here are the steps to follow:

1. Safeguard the Tester: Ensure the tester is in a stable environment with proper lighting and minimal vibrations.
2. Power On: Turn on the tester and check if all components, such as the load cell and sensors, are functioning correctly.
3. Attach Calibration Weight: Place the calibration weight on the load cell to ensure accurate measurements.
4. Adjust Sample Positioning: Ensure the sample position aligns with the specified location on the tester. Proper alignment is crucial for obtaining consistent results.

Calibration Steps

Calibrating the tester is a critical step to ensure accurate and reliable results. Here are the recommended calibration processes:

1. Initial Calibration: Perform an initial calibration before starting any tests. This ensures that the tester is set correctly and starts the test in the right state.
2. Daily Calibration: Calibrate the tester at the beginning of each testing session to maintain consistency in measurements.
3. Bi-weekly Calibration: Conduct a more thorough calibration every two weeks to ensure long-term accuracy.

Consistency Tips

To maintain consistency in your tests, follow these tips:

• Regular Maintenance: Regularly clean and maintain the tester to prevent any buildup of dust or debris that could impact readings.
• Consistent Sample Preparation: Ensure that all samples are prepared in the same manner before testing.
• Standard Conditions: Maintain consistent environmental conditions, such as temperature and humidity, during testing.

Test Procedure

Conducting Tests

The test procedure for the ISO 17707 Shoe Flexural Stiffness Tester involves several steps. Here's a breakdown of the process:

1. Loading the Sample: Insert the shoe sample into the testing device according to the manufacturer's guidelines.
2. Securing the Sample: Ensure the sample is securely positioned and aligned correctly.
3. Applying Load: Apply the specified load to the sample using the load cell. The load should be distributed evenly to avoid any skew in the measurements.
4. Recording Data: Once the load is applied, record the resulting flexural stiffness values. This data will be used for analysis later.

Key Parameters

Several key parameters are critical for obtaining accurate test results:

• Load Cell Settings: Ensure the load cell is set to the correct value as per the ISO 17707 standard.
• Sample Positioning: Proper positioning of the sample is crucial. Misalignment can lead to inaccurate results.
• Environmental Conditions: Maintain consistent temperature and humidity during testing to avoid variations in test outcomes.

Best Practices

To ensure your tests yield consistent and accurate results, follow these best practices:

• Operator Skill Level: Ensure the operator is trained and experienced in operating the tester.
• Regular Calibration: Maintain regular calibration schedules to prevent drift over time.
• Sample Consistency: Ensure all samples are prepared and positioned identically.

Maintenance and Calibration

Regular Maintenance Tasks

Maintaining the tester is essential for ensuring its longevity and accuracy. Here are some recommended maintenance tasks:

1. Cleaning: Regularly clean the tester to remove any dust or debris that could interfere with the measurements.
2. Component Inspection: Inspect all components, including the load cell and sensors, for any signs of wear or damage.
3. Documentation: Keep detailed records of all maintenance activities, including calibrations and inspections.

Calibration Procedures

Calibration is a critical process that involves checking and adjusting the tester's accuracy. Here are the recommended procedures:

1. Initial Calibration: Perform an initial calibration before the first test.
2. Daily Calibration: Calibrate the tester daily to ensure consistent accuracy.
3. Bi-weekly Calibration: Conduct a more thorough calibration every two weeks.

Importance of Calibrations

Regular calibrations are essential to ensure that the tester continues to produce accurate results over time. Drift and wear can occur, even with regular usage, which can affect the accuracy of your measurements.

Analyzing Test Results

Interpreting Results

Once the tests are completed, the next step is to analyze the results. Here's how to interpret the data:

1. Data Review: Review the recorded results to ensure they are within the expected range.
2. Anomaly Detection: Check for any anomalies in the data that might indicate a problem with the tester or the sample.
3. Trends and Patterns: Look for trends and patterns in the data to identify any systematic issues.

Identifying Anomalies

Common anomalies that might occur during testing include:

• Inconsistent Load Cell Readings: If the load cell readings are inconsistent, it could indicate a problem with the load cell itself or with the sample positioning.
• High Variability in Results: If there is high variability in the results, it might indicate inconsistency in sample preparation or alignment.

Common Issues and Solutions

Best Practices for Test Repeatability

Tips for Consistent Results

To achieve repeatable results, follow these best practices:

1. Standard Procedure: Ensure that the testing procedure is standardized across all tests. This includes sample preparation, positioning, and measurement conditions.
2. Through Training: Train operators to follow the standard procedures consistently.
3. Regular Calibration: Maintain regular calibration schedules to ensure accuracy.

Factors Impacting Repeatability

Several factors can impact the repeatability of your tests:

• Sample Variability: Variations in sample preparation or positioning can lead to inconsistent results.
• Environmental Conditions: Changes in temperature or humidity can impact the test results. Ensure a stable testing environment.
