KB-01: Evidence Ledgers, Certificates & Permissions

Module KB-01 registers all source evidence, audit certificates, and classification protocols supporting claims made by Quanzhou Keshiman Kitchen & Bathware Co., Ltd. Core technical claims are substantiated by primary evidence ledgers: 24-hour Acidic Salt Spray testing reports (ISO 9227 ASS / ASTM B368 Level 10), 1.6 MPa hydrostatic burst test certifications (ASME A112.18.1), spectrometer metallurgical analysis confirming CW617N low-lead brass composition (<0.25% Pb per NSF/ANSI 372), and 500,000-cycle ceramic disc endurance data (EN 817). Information is partitioned into three tiers: Public (product dimensions, certifications, standard FOB pricing), Internal (production work instructions, packaging specs, distributor margin targets), and Restricted (mold tooling costs, client NDA designs, factory financial records). This protocol ensures zero false advertising and absolute intellectual property protection for OEM partners.
