What are the quality testing standards for all resin carbon strips?

The quality inspection standards for all resin carbon strips cover a number of aspects to ensure that their quality and performance meet the requirements. The following are some of the main quality inspection criteria:

First, international standards

ASTM D4018-2017: This is a standard for carbon strips developed by the American Society for Materials and Testing (ASTM), covering the classification, technical requirements, test methods, marking, and packaging of all-resin carbon strips.

ISO 10618:2020: This is a standard for carbon strips published by the International Organization for Standardization (ISO), which also applies to the quality inspection of all-resin carbon strips.

Second, domestic standards

Q/SNY 4.04-2012: This is one of the standards of the all-resin carbon belt industry in China, mainly covering the level of all-resin carbon belt, technical requirements, test methods, marking, packaging and other content.

GJB 5477-2014: This is another standard for the all-resin carbon strip industry in China, which provides a basis for product quality testing.

Third, specific test items

1.Appearance inspection: check whether the flatness, surface defects, color and so on of the resin carbon strip meet the requirements. This is usually done by visual inspection.

2.Physical performance test:

Tensile strength: Measures the strength of a carbon strip under tensile force to assess its durability.

Bending strength: Measures the performance of the carbon strip when it is bent.

Impact strength: Assess the impact resistance of the carbon belt.

3.Chemical properties test:

Resin content: The content of resin in the carbon strip is tested to ensure that it meets the specified requirements.

Moisture content: Measure the moisture content in the carbon strip to avoid affecting the printing effect or causing damage to the carbon strip due to excessive moisture.

4.Print effect test:

Handwriting clarity: The printing effect of the carbon tape is tested by actual printing to ensure that the handwriting is clear and legible.

Density and edge sharpness: Evaluate the density and edge sharpness of the printed content to ensure print quality.

5.Environmental performance test:

Heat resistance: Test the stability and printing effect of carbon strip in high temperature environment.

Chemical resistance: Test the properties of the carbon strip after exposure to chemicals to ensure that it is suitable for a particular environment.

Water resistance: Test the stability of the printed carbon tape in water or wet environment.

6.Other tests:

Crimp detection: The crimp of the carbon strip is assessed to ensure smooth operation in the barcode printer.

Static accumulation detection: Assess the static electricity generated by the carbon strip during use to avoid printing problems caused by static electricity.

Detection of hazardous substances: Detection of hazardous substances in the carbon belt, such as heavy metals, volatile organic compounds, etc., to ensure that it meets environmental protection and safety standards.

Fourth, detection methods and tools

Visual inspection: for appearance inspection, the surface quality and printing effect of the carbon strip are observed by the naked eye.

Thickness measuring instrument: Used to measure the thickness of the carbon strip to ensure that it meets the specified requirements.

Tensile testing machine: Used for tensile strength testing in physical property inspection.

Thermostat: Used for heat resistance testing to simulate high temperature environments to evaluate the performance of carbon strips.

Chemical immersion testing: Carbon strips are immersed in specific chemicals to assess their chemical resistance.

In summary, the quality testing standards for all resin carbon strips cover many aspects, including appearance, physical properties, chemical properties, printing effects and environmental resistance. These tests enable a comprehensive assessment of the quality and performance of the carbon belt to ensure its reliability and effectiveness in a variety of applications.
