Product Overview
Biochemazone Artificial Perspiration ISO 3160-2 – Stabilized BZ127 is a ready-to-use, sterile, stabilized acidic artificial sweat at pH 4.7 for the corrosion-resistance test of ISO 3160-2. The standard covers gold alloy coverings on watch cases and accessories, and the sweat exposure shows whether a covering tarnishes, oxidises or is penetrated – on the case itself and on bracelets permanently attached to it.
The Stabilized version contains a preservative / stabilizer system that keeps the solution free of microbial growth through repeated opening over a long test programme. If your protocol requires solution without preservative or stabilizer, order the not-stabilized version (BZ123) or the Powder Version Kit; BZ124 is an equivalent stabilized listing. Prepared with ISO 3696 compliant high-purity water under Biochemazone’s ISO 9001 / GMP quality system, every batch is standardised for composition and pH. Other pH values from 2 to 9 are supplied on request at no extra cost.
BZ127 is used by watch and jewellery manufacturers, electroplaters, PVD coaters and testing laboratories to qualify gold-plated and gold-covered cases, bracelets, clasps and accessories, and more widely as an aggressive acidic sweat for the corrosion testing of decorative coatings. See also Artificial Perspiration ISO 3160-2 with Pyruvic Acid, Buffered BZ617 and Simulated Perspiration ISO 2812-1, pH 4.7 BZ408.

Frequently Asked Questions
Why choose the stabilized version?
Corrosion tests on watch cases are often run in series over weeks. The stabilizer system keeps an opened bottle free of microbial growth, so the same lot can be used through the whole programme, and gives a 1-year shelf life unopened.
Is a not-stabilized ISO 3160-2 solution available?
Yes – Artificial Perspiration ISO 3160-2 – Not Stabilized BZ123 is the same pH 4.7 solution without preservative or stabilizer, with a 6-month shelf life unopened.
