Когда партия не проходит EN 1811: перепокрывание, переиспытания и где на самом деле граница списания

Short answer: Sometimes, but not on the same evidence. A failed EN 1811 batch can be stripped and re-plated when the nickel comes from the coating system itself: a nickel strike or underplate, a contaminated plating bath, or a coating that is too thin at an edge. It should be scrapped when the nickel sits ... <a title="When a Batch Fails EN 1811: Re-Plating, Retesting, and Where the Scrap Line Actually Is" class="read-more" href="https://amarajeweiry.com/ru/en1811-failed-batch-replate-or-scrap/" aria-label="Прочитать больше о When a Batch Fails EN 1811: Re-Plating, Retesting, and Where the Scrap Line Actually Is">Читать далее</a>

Кольцо S925 с пробой 91,8% серебра: правило 4/1000, допуск на припой и когда подавать рекламацию

At 91.8% silver, an S925 ring is three parts per thousand away from two different verdicts. Under 15 U.S.C. § 296, a 925 mark allows a 4/1000 deviation on the solder-free silver, so the floor is 921‰; at 918‰ the ring fails by 3/1000 and the result supports a claim. If the laboratory assayed the ... <a title="S925 Ring Assayed at 91.8% Silver: The 4/1000 Rule, the Solder Allowance, and When to Raise a Claim" class="read-more" href="https://amarajeweiry.com/ru/s925-assay-918-silver-tolerance/" aria-label="Прочитать больше о S925 Ring Assayed at 91.8% Silver: The 4/1000 Rule, the Solder Allowance, and When to Raise a Claim">Читать далее</a>

Лазерная гравировка вашего бренда рядом с клеймом 925: правила размещения, срок и цена за единицу на серии 10 000 колец

Short answer: On a 10,000-unit S925 ring run, laser etching your brand name adds days rather than weeks, and a small per-piece charge once the mark file and fixture exist – but placement is a legal decision before it is a design one. Under the National Gold and Silver Stamping Act, 15 U.S.C. § 297(b), ... <a title="Laser Etching Your Brand Name Next to the 925 Stamp: Placement Rules, Lead Time, and Per-Unit Cost on a 10,000-Ring Run" class="read-more" href="https://amarajeweiry.com/ru/laser-etching-925-hallmark-lead-time-cost/" aria-label="Прочитать больше о Laser Etching Your Brand Name Next to the 925 Stamp: Placement Rules, Lead Time, and Per-Unit Cost on a 10,000-Ring Run">Читать далее</a>

Бронза, проступающая сквозь S925 с покрытием за три месяца: входной тест, пункт PO и кто платит

Direct answer: Bronze showing through a plated S925 chain three months into retail is not proof of wearer abuse, and it is not automatically a plating defect either. Color alone cannot separate the two, because a silver sulfide film reads yellow-brown before it reads black, while a brass substrate that was marked 925 reads bronze ... <a title="Bronze Showing Through Plated S925 in Three Months: The Receiving Test, the PO Clause, and Who Pays" class="read-more" href="https://amarajeweiry.com/ru/%D0%B4%D0%B5%D1%84%D0%B5%D0%BA%D1%82-%D0%BF%D0%BE%D0%BA%D1%80%D1%8B%D1%82%D0%B8%D1%8F-%D0%BA%D1%82%D0%BE-%D0%BF%D0%BB%D0%B0%D1%82%D0%B8%D1%82/" aria-label="Прочитать больше о Bronze Showing Through Plated S925 in Three Months: The Receiving Test, the PO Clause, and Who Pays">Читать далее</a>

Клеймение UK и EU для ювелирных изделий из серебра S925: четыре клейма, пробирная палата и досье, которого ждёт ваш покупатель

Short answer: A US or EU retail chain will not review an S925 silver line until four folders exist: commercial documents (licence, tax ID, insurance, NDA), a compliance pack (third-party test reports for nickel release, lead, cadmium and REACH or CPSIA limits), quality records (AQL inspection results, fineness and plating data), and UK/EU hallmarking evidence. ... <a title="UK and EU Hallmarking for S925 Silver Jewelry: The Four Marks, the Assay Office, and the File Your Buyer Expects" class="read-more" href="https://amarajeweiry.com/ru/%D0%BA%D0%BB%D0%B5%D0%B9%D0%BC%D0%B5%D0%BD%D0%B8%D0%B5-uk-%D0%B8-eu-%D1%81%D0%B5%D1%80%D0%B5%D0%B1%D1%80%D0%BE-s925/" aria-label="Прочитать больше о UK and EU Hallmarking for S925 Silver Jewelry: The Four Marks, the Assay Office, and the File Your Buyer Expects">Читать далее</a>
