Artificial Eccrine for Corrosion Testing

 The following text provides an overview of various formulations of artificial perspiration used for corrosion and chemical resistance testing of wearables and other products that are in prolonged contact with human sweat. These formulations are designed to simulate the corrosive effects of sweat on various materials and surfaces and to determine their resistance to corrosion, tarnishing, oxidation, discoloration, and other forms of wear and tear caused by prolonged exposure to sweat. The text also includes relevant standards and test procedures for the use of these formulations in specific applications, such as testing builders’ hardware finishes, ophthalmic optics, shoe upper leather, and automotive trim materials and components.

BS EN 1811:2011 Artificial Perspiration for Nickel Release

This particular formulation, with a pH level of 6.5, has been developed to promote the release of Nickel from post assemblies that are inserted into pierced areas of the human body. Additionally, it is suitable for articles intended for direct and prolonged contact with the skin. It’s important to note that this European Standard does not apply to spectacle frames and sunglasses. Custom pH levels and stabilized versions of this formulation are also available upon request.

ISO 3160 Artificial Perspiration for Corrosion Resistance for Gold Alloy

This particular test has been specifically designed to evaluate the extent of corrosion resistance that gold alloy coatings offer to watch cases and accessories, including bracelets that are permanently attached to the case. The test solution, which has a pH value of 4.7, adheres to the standards laid out in ISO 3160 specifications. It’s worth noting that customized pH values and stabilized versions of the solution are also available, depending on the requirements of the testing process. The test evaluates the level of tarnishing, oxidation, and surface penetration that these coatings can withstand, allowing manufacturers to determine the effectiveness of their products in real-world conditions.

ANSI-BHMA A156.18 Artificial Perspiration For Testing Builders Hardware and Finishes

This synthetic sweat is specially crafted to examine the quality of various base materials as per the regulations established by the Builder’s Hardware Association. However, it’s important to note that this particular compound is not available in a stabilized form. Nonetheless, if you need a bespoke pH level to suit your specific testing requirements, we would be delighted to offer this service to you.

GMW14334 Artificial Perspiration for Chemical Resistance of Automotive Trim Materials and Components

The acid and alkaline perspiration solutions are meticulously prepared following the test procedure outlined in GMW14334. These solutions are specifically formulated to evaluate the chemical resistance of various automotive trim materials and components.

DIN EN 60068-2-70 & IEC 60068-2-70 Artificial Perspiration for Abrasion Resistance of Markings and Letterings Caused by Rubbing of Fingers and Hands

This formula is utilized to assess the durability of markings and lettering on both flat and curved surfaces when exposed to potential abrasion from manual actuation and keyboard use. Additionally, it serves to determine resistance to fluid contamination under typical usage conditions.

ISO 12870 Artificial Perspiration for Ophthalmic Optics – Spectacle Frames

This test method is utilized to evaluate the perspiration resistance of unglazed eyeglass frames suitable for use with prescription lenses, as well as rimless, semi-rimless, and folding frames. The method also applies to frames constructed from natural organic materials, but it does not apply to custom-made frames or products designed solely for personal eye protection.

ASTM Method D2322-00 Artificial Perspiration For Resistance to Grain Cracking, Area Loss, and Flexibility of Shoe Upper Leather

ASTM method D2322-00 determines the resistance of shoe upper leather to artificial perspiration, including grain cracking, area loss, and flexibility. Custom versions with pH and stability adjustments are available.

In conclusion, the text provides valuable insights into the importance of using artificial perspiration formulations for testing products and materials that come into prolonged contact with human sweat. This is essential to ensure their corrosion and chemical resistance and to prevent harmful effects on human health. The knowledge of the corrosive effects of sweat and the use of artificial perspiration formulations can prevent tarnishing, loss of gloss, shrinkage, cracking, and discoloration of wearables and other products, thereby ensuring their longevity and safety.

pH can be customized on request as per the customer’s project requirement without any additional cost.
