Standards

The design and manufacture of the continuity tester for the inner coating of aluminum tubes usually comply with a series of national and international standards to ensure the accuracy and reliability of test results. Among them, common standards include YBB00162002 - 2015 Aluminum Pharmaceutical Soft Tubes, etc. These standards specify in detail the test methods, specimen preparation, test conditions, etc. for the continuity of the inner coating of aluminum tubes, providing a unified standard for the use of the tester.

Features

1. High Specialization: Specifically designed for continuous testing of the inner coating of aluminum tubes, compatible with common aluminum tube specifications of 8-45mm diameter and 35-250mm length, covering most industry application scenarios.

2. High Testing Accuracy: Current measurement accuracy reaches ±0.1mA, accurately identifying minute coating damage and ensuring reliable test results.

3. Flexible Adaptability: The test voltage is adjustable (e.g., DC 5V±0.5V), matching the testing needs of different coating materials and thicknesses.

4. Portable and Easy to Deploy: Compact and lightweight, it can be flexibly deployed in various scenarios such as production sites and laboratories.

5. Multi-Scenario Coverage: Supports full-process applications including raw material quality inspection, new product R&D assistance, and in-use product quality control, contributing to quality management.

Accessoriess

Multi-size aluminum tube clamps: Adaptable to aluminum tubes with diameters of 8-45mm and lengths of 35-250mm, ensuring stable sample clamping.

Standard calibration aluminum tubes: Aluminum tube samples with known coating conditions, used for periodic accuracy calibration of the equipment.

Internal coating electrode probe: The detection component that contacts the inner coating of the aluminum tube, ensuring stable transmission of electrical signals.

Data transmission cable: Connects the equipment to a computer, enabling the export and storage of test data.

Probe cleaning brush: Cleans the surface of the electrode probe to prevent coating residue from affecting detection accuracy.

Test Procedures

1. Equipment Preparation

Connect to AC 220V 50Hz power supply. Confirm the working environment (23℃±2℃, humidity ≤80%, non-condensing). After powering on and preheating, calibrate the equipment using a standard calibration aluminum tube.

2. Sample Preparation

Select the aluminum tube to be tested and clean its inner surface (remove impurities). Confirm that the dimensions are within the equipment's testing range.

3. Parameter Setting

Set the test voltage (e.g., DC 5V±0.5V) through the equipment interface, matching the coating material and thickness.

4. Sample Clamping

Fix the aluminum tube in the corresponding specification clamp, ensuring full contact between the electrode probe and the inner coating.

5. Start Testing

Run the testing program. The equipment automatically detects the electrical continuity of the coating and records the data.

6. Result Determination

Determine whether there are defects such as discontinuities or breaks in the coating based on the current data.

7. Post-processing

Remove the sample, clean the electrode probe, export the data, and generate a test report.
