Quand un lot échoue à EN 1811 : replaquage, contre-essai et où se trouve vraiment la ligne de rebut

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/fr_fr/en1811-failed-batch-replate-or-scrap/" aria-label="En savoir plus sur When a Batch Fails EN 1811: Re-Plating, Retesting, and Where the Scrap Line Actually Is">Lire la suite</a>

Bague S925 dosée à 91,8 % d’argent : la règle 4/1000, la tolérance de soudure et quand ouvrir une réclamation

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/fr_fr/s925-assay-918-silver-tolerance/" aria-label="En savoir plus sur S925 Ring Assayed at 91.8% Silver: The 4/1000 Rule, the Solder Allowance, and When to Raise a Claim">Lire la suite</a>

Graver au laser votre nom de marque à côté du poinçon 925 : règles de placement, délais et coût unitaire sur une série de 10 000 bagues

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/fr_fr/laser-etching-925-hallmark-lead-time-cost/" aria-label="En savoir plus sur Laser Etching Your Brand Name Next to the 925 Stamp: Placement Rules, Lead Time, and Per-Unit Cost on a 10,000-Ring Run">Lire la suite</a>

Bronze qui Affleure sous le S925 Plaqué en Trois Mois : le Test de Réception, la Clause du BC et Qui Paie

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/fr_fr/vice-de-placage-qui-paie/" aria-label="En savoir plus sur Bronze Showing Through Plated S925 in Three Months: The Receiving Test, the PO Clause, and Who Pays">Lire la suite</a>

Poinçonnage britannique et UE pour la Joaillerie en Argent S925 : les Quatre Poinçons, le Bureau de Garantie et le Dossier qu'Attend votre Acheteur

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/fr_fr/poinconnage-uk-et-ue-argent-s925/" aria-label="En savoir plus sur UK and EU Hallmarking for S925 Silver Jewelry: The Four Marks, the Assay Office, and the File Your Buyer Expects">Lire la suite</a>
