Certified Door Hardware: Quality Integrity Declaration
Certification Compliance Framework
1, Certified Manufacturer's Non-certified Products
Produced under identical quality systems but without third-party certification marks
2, Certified Product Definition
Compliance verified through random batch sampling (per EN 1906:2012 Clause 8.2)
Maintains Grade 3/4 performance thresholds across full production runs
Quality Alert: Electroplating Nonconformance for Ferrous Components
Standard Rework Protocol
1.Nonconformance Identification
Failed components undergo ASTM B117 salt spray testing (72hrs minimum)
2. Full-Strip Reprocessing
Certified stripping using EN 12540-compliant chemical baths
Three-stage ultrasonic cleaning (DI water > Alkaline > Acidic)
3. Re-plating Verification
Cross-section microscopy to validate base metal integrity
Adhesion testing per ISO 2819 (≥8MPa required)
Unapproved Shortcut Practice
Illegitimate Process Flow:
Contravenes RoHS Directive 2011/65/EU Article 4(1)
Electroplating Nonconformance for Iron-Based Components
This document addresses issues related to internal components (iron-based parts) that require processing, electroplating, inspection, and assembly prior to installation. However, nonconforming electroplating results frequently occur during production.
Standard Nonconformance Handling Process:
1, Return defective components to the plating vendor.
2, The vendor must professionally strip all defective plating layers, perform thorough cleaning, and re-plate the components.
Unapproved Shortcut Practice:
Some suppliers occasionally use prohibited chemical agents to locally remove defective plating areas without full stripping, followed by direct re-plating. This method evades detection during routine inspections and standard salt spray testing (e.g., ASTM B117).

Simple and clean is universally recognized beauty
Simple and clean is universally recognized beauty.
On the market, some simple product clean but without beauty. Cause by the less refined of production process, and its related process control which can be sure to achieve it.
At the moment of serious homogenization of products, this is one of the open secrets that distinguishes us from others.
