Industrial products from China are continually becoming the preferred materials and equipment for global manufacturing and service sectors.
InTouch carefully formulates its industrial products inspection processes to cover every key point essential to your business and customers. Here is a sample of a few of the inspections that InTouch uses in developing inspection protocols:
During Production Inspection Processes (DUPRO)
- Manufacturing Procedure Verification – Verify that industrial product supplier practices standard operating procedures on the production floor.
- Manufacturing Equipment – Verify that supplier maintains the necessary manufacturing equipment to guarantee timely delivery of your product.
- Raw Materials Verification – Check that supplier uses only specified grades and volume of raw materials.
- Coating and Finishing Materials – Verify that supplier adheres to specified coating and finishing materials.
Visual Inspection
- Color Comparison – Compare color of finished industrial product with approved samples or specified values in the Pantone color chart.
- Overall Appearance – Compare finished product with approved samples for any sign of deviation in overall appearance.
- Coat Inspection – Check thickness and quality of coating, and compare with approved samples, if present. Perform specific coat tests such as Rub Check, whenever applicable.
- Manufacturing Defects – Check for any sign of manufacturing defect giving emphasis on pre-identified critical parts under ambient lighting conditions.
- Product Uniformity – Verify that there is uniformity in overall appearance of finished products; a trait associated with superior product quality.
- Permanence of Marking – Verify that logos and related markings do not peel off from product when exposed to conditions above normal usage.
Functional Inspection
- Power Consumption and Efficiency – Verify power consumption, efficiency, and ratings of electrical industrial products.
- Rated Capacity Check – Verify rated capacity by using standard tests and parameters applicable to the product.
- Ease of Operation – Evaluate the likelihood that users of varied skill levels are able to operate the product effectively.
- Safety Features – Evaluate industrial product safety features, giving emphasis on clarity of instructions, and conspicuousness of safety mechanisms.
- Accelerated Life Testing – Evaluate effective service life of product using applicable accelerated life testing procedures.
- Corrosion Resistance – Evaluate the corrosion resistance using techniques applicable to product.
Performance Inspection for Electrical Industrial Products
- Leakage Current Test – Verify that the current that flows out of the equipment when a person touches it are below hazardous levels.
- Power Input Test – Determine the power requirement of equipment.
- Temperature Test – Check equipment temperature after running it continuously for a specified period. It should not exceed safe levels.
- Dielectric Voltage-Withstand Test – Verify the reliability of product’s electrical insulation system using the Hipot Test.
- Humidity Conditioning – Determine how product behaves after exposure to a controlled humid environment for a specified period.
- Strain Relief Test – Test integrity of electric cable by letting a specified amount of force pull it in both ends.
- Overload Test – Verify integrity of electrical system by subjecting the product to current above its normal rating.
- Impact Test – Evaluate strength and rigidity product when hit by an oncoming object of controlled weight and velocity.
- Drop Test – Evaluate product integrity when dropped from a specified height on a flat surface with pre-determined rigidity.
- Tip-over Check – Verify that product stability does not exceed standard limits.
Dimensional Inspection
- Individual Parts – Verify that parts dimensional measurement are within standard limits.
- Assembled Product – Check fully assembled product for nonconformance to standard dimensional measurement.
- Advanced Dimensional Testing – Perform advanced dimensional testing for industrial products that require high levels of precision. Whenever in-house testing is not applicable, the wide network of testing laboratories affiliated to InTouch may perform the necessary tests.
- Density – Measure relative density of product for compliance with agreed upon values; applicable mostly with raw materials.
- Weight – Measure weight of finished product and compare with approved values.
