Description (English):

La présente partie de la norme prescrit les exigences afférentes aux matériaux constitutifs et aux performances des articles d'orfèvrerie de table et décorative en métal argenté, fabriqués principalement à partir de métaux et destinés à être utilisés à table ou sur une table, ainsi que les méthodes d'essai. Des valeurs limites de composition sont fixées pour les métaux de base entrant dans la fabrication des articles d'orfèvrerie avant revêtement d'argent. La présente norme s'applique également aux objets décoratifs, tels que les vases et les trophées, et à d'autres articles tels que les pots, plats, théières et cafetières, plateaux et soupières, bougeoirs, seaux à champagne, etc. Les diverses exigences portent sur les articles d'orfèvrerie en laiton, cuivre, maillechort, étain et acier inoxydable, revêtus d'argent, ainsi que sur les accessoires coulés en métal argenté qui y sont associés. Les différentes épaisseurs des revêtements d'argent sont classées dans trois catégories : classes I, II et III. Ces revêtements peuvent également être protégés par une couche de vernis. La présente norme n'est applicable ni aux articles d'orfèvrerie entièrement fabriqués en métaux précieux, laiton, maillechort, étain, acier inoxydable, ni ceux fabriqués en céramique ou en verre.

Abstract

Overview

ISO 8442-3:1997 - Materials and articles in contact with foodstuffs - Cutlery and table holloware - Part 3: Requirements for silver-plated table and decorative holloware specifies material, construction, performance and testing requirements for silver‑plated tableware and decorative holloware intended for use at or on the dining table. It covers a wide range of items (jugs, trays, tea/coffee pots, tureens, candlesticks, vases, trophies, etc.) made principally from base metals and finished with a silver coating. The standard focuses on safety, durability and suitability for food contact rather than design or size.

Key topics and technical requirements

Scope & materials: Applies to silver‑plated holloware made from brass, copper, nickel‑silver, pewter and stainless steel; silver coatings must be at least 98.5% Ag. It does not apply to items made entirely of precious metals, ceramics or glass.
Silver coating classes & thickness:
- Three quality classes (First, Second, Third) with specified average thicknesses for functional and non‑functional surfaces (e.g., First class table holloware functional = 15 μm, non‑functional = 3 μm).
- Local thickness must be ≥ 60% of the average; measurement methods referenced include ISO 1463, ISO 2177, ISO 3497, ISO 3543.
Construction & finish: Surfaces must be free of cracks, burrs and gaps > 0.4 mm; seams watertight unless design requires otherwise.
Lacquered products: If lacquer is present, requirements include resistance to dishwashing (50 cycles), scratching (Annex C) and UV (Annex D).
Performance tests (Normative annexes C–K): Methods for resistance to scratching, UV, twisting, popping, load strength of vessels, strength of attachments, pouring behavior, handle temperature and leakage, and adhesion (heat/quench test: 250 °C ± 10 °C for 30 min ± 5 min, then quench).
Performance criteria: Limits for deformation, popping, attachment strength, stability (clearance limits by item width), pouring without dribbling, handle temperatures, and adhesion of plating.

Applications and who uses this standard

Manufacturers and finishers of silver‑plated tableware and decorative holloware - to design, plate and certify products.
Quality assurance and test laboratories - to perform mandated thickness, adhesion and mechanical performance tests.
Procurement and hospitality sectors - to specify durable, food‑safe silver‑plated items.
Regulatory bodies and importers - for compliance with food contact and durability requirements (references EC Directives 89/109 and 90/128 are noted).
