Quality Standards And Testing Methods For Hardware Accessories
Quality standards and testing methods of Hardware Powerfitting
The quality standards of hardware accessories mainly include materials, craftsmanship, load-bearing capacity, sealing, brand and reputation, while the testing methods cover multiple aspects such as appearance testing, component analysis, corrosion resistance testing, weather resistance testing, and coating thickness and adhesion determination.
1. Quality standards
Material:
Common hardware materials include stainless steel, copper, zinc alloy, etc.
Stainless steel has the advantages of rust resistance and corrosion resistance, and is suitable for use in humid environments.
Copper hardware has good texture and is durable, but the price is relatively high.
Zinc alloy has a lower cost and a variety of styles.
Craftsmanship:
The surface of high-quality hardware should be smooth and flat, without burrs, scratches and defects.
The corners of the handle should be rounded to avoid scratching the hand.
The opening and closing of the hinge should be smooth without jamming.
Load-bearing capacity:
The load-bearing capacity of hardware accessories must meet the use requirements. For example, the slide rail needs to be able to bear a large weight and slide smoothly.
Sealing property:
For hardware accessories that need to be sealed, such as faucets, their sealing performance needs to be checked to prevent water leakage.
Brand and reputation:
Well-known brands are usually more secure in terms of quality control and after-sales service.
II. Testing methods
Appearance inspection:
Check whether there are scratches, pores, pits, flash, sharp edges, burrs and other defects on the surface of hardware accessories.
The actual object must be completely consistent with the logo, and the packaging must not be damaged.
Composition analysis:
Through chemical composition analysis, ensure that the materials of hardware accessories meet the regulations and do not contain substances harmful to the human body.
Corrosion resistance test:
Carry out neutral salt spray test of coating, acetic acid accelerated salt spray test, etc. to evaluate the corrosion resistance of hardware accessories.
Weather resistance test:
Through artificial xenon lamp accelerated weathering test, simulate various climatic conditions and evaluate the weather resistance of hardware accessories.
Coating thickness and adhesion measurement:
Measure the thickness of the coating and evaluate whether its adhesion is strong enough.
Other tests:
Depending on the specific type and use requirements of hardware accessories, hardness testing, size inspection, combination assembly inspection and tooth pattern inspection may also be required.
In summary, the quality standards and testing methods of hardware accessories involve many aspects, and it is crucial to ensure the quality and safety performance of hardware accessories.
