Detection textiles needle type residues
1 Scope
This standard specifies the method using a metal detector needle machine needle in the textiles category or ferromagnetic metal residues.
This standard applies to through the production and processing of textile products. Raw materials, semi-finished products and other products may refer to use.
Principle 2
Principle of electromagnetic induction, so that the textile products in the category needle or ferromagnetic metal residues occur sensors so as to be detected.
3 Testing Equipment
3.1 Testing Equipment
According to detect the nature of the subject and the type of textile products related standards and form selection with appropriate sensitivity detection equipment.
3.1.1 transport metal needle machine. used textiles production and processing enterprises, textile products detected in needles left behind iron, iron and other ferromagnetic
Substances can also be used to detect the detection mechanism for textile products in categories needle or ferromagnetic metal residues. Common detection sensitivity (standard iron
Ball test card, also known as the standard needle test block) have. 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm and 3.0mm.
3.1.2 Desktop metal detector. for small pieces, thin pieces, bedding and other textile products in categories needle or ferromagnetic metal residues detection
Measurement. Common detection sensitivity (standard iron ball test card, also known as the standard needle test block) have. 1.0mm, 1.2mm, 1.5mm and
2.0mm.
3.1.3 hand-held metal detector. for the detection of small pieces, thin pieces of broken needles and other textile products in class or ferromagnetic metal residues may also be
Other auxiliary needle machine accurate detection of defective needle class or ferromagnetic metal residues. Common detection sensitivity (standard iron ball test card,
Also known as the standard needle test block) have. 0.8mm, 1.0mm and 1.2mm.
3.2 Operating Environment
3.2.1 Detection equipment should stay away from magnetic sources (such as large transformers, high voltage power lines, electric fans, motors, etc.) and local oscillator.
3.2.2 testing equipment around 1m or less without any ferromagnetic metal objects.
3.3 calibration requirements
3.3.1 each calibration, should be turned off, wipe testing equipment.
3.3.2 testing equipment to normal operation after startup, calibration.
3.3.3 testing equipment officially detection, calibration should be performed for the first time every time.
3.3.4 Detection equipment should be calibrated at least once a continuous work within 2h.
3.3.5 concludes, response testing equipment for the last calibration.
3.3.6 shall designate a person calibration and testing, staff shall not carry watches, cell phones, keys, metal buckle with a magnetic leader belts
Items.
3.3.7 Calibration with iron ball test card selected according to the detection sensitivity of the device or intended size thereof.
3.3.8 Calibration transport metal needle machine using 9 test method (see Appendix A) for calibration. Desktop can refer to the use of metal detectors.
3.3.9 hand-held metal detector after each boot, and issued a tweet appeared luminescent signal, the power to meet the requirements, or need to replace the
Source; standard iron ball test card placed in hand-held metal detector square meter surface of the effective height, can trigger the alarm sound, then meet
Testing requirements; otherwise requires inspection, repair and testing equipment, iron ball until the standard tests until the alarm card declined.
4 Sample Preparation
Samples were organized into easy to shape detection. If the height of the folded samples above the detection equipment gantry height, width greater than the effective
