DEC STD 092-0

This document, "DEC STANDARD 092," is a comprehensive "FINISH AND COLOR STANDARD" issued by Digital Equipment Corporation. It is organized into multiple sections, designed to provide guidelines and requirements for the finishes and colors used on Digital products, with each section capable of standing alone as a separate standard.

The primary purpose of the standard is to ensure that all finish materials and finished parts meet Digital's quality specifications. It outlines procedures and requirements for Digital personnel and external vendors involved in the selection, application, and testing of finishes.

Key areas covered by the standard include:

• Introduction and General Requirements (Section 0): Defines the overall purpose, scope, and responsibilities of various internal groups (Systems Materials Engineering, Digital Materials Research Lab, Design Services) and external entities (Finish Applicators, Coating Material Suppliers) in adhering to the standard. It also lists referenced external and internal documents.
• Finish Standard for Applicators (Section 1): Provides detailed information for finish applicators, including Digital's finish numbering system, general finish rules, appearance quality criteria, and test panel information. The numbering system is a 3-4-3 format (e.g., 092-AXXY-CCC) specifying material group, surface variation, quality level (based on viewing distance), and color code.
• Finish Material Standard for Suppliers (Section 2): Defines the procedures and requirements for finish material suppliers, covering supplier approval, new material approval processes, requirements for sample evaluation (including compatibility with touch-up, silk screen, and decals), batch (lot) approval, and preparation for shipment.
• Finish Material Test Requirements (Section 3): Specifies the environmental, physical, and appearance quality tests and methods applied to finishes used on Digital parts. This includes tests for salt spray, humidity, corrosive vapors, solvent resistance, wear resistance (Taber abrasion), scratch hardness, flexibility, impact, adhesion, film thickness, gloss, color, and texture matching.
• Approved Finish Specifications (Section 4): Contains a complete list of all currently approved finish specifications for Digital products, categorized by type (paint, metal plating, conversion/oxide coatings), and provides a cross-reference for previously used numbering systems.
• Digital Color List (Section 5): Provides a comprehensive list of all approved Digital colors and their corresponding identification numbers.
• Digital-Approved Paint Suppliers and Material Identification (Section 6) & Plastic Color Control and Material Identification (Section 7): These sections, although not fully detailed in the provided excerpt, are listed as components of the standard, likely listing approved suppliers and color control for plastics.

In summary, DEC STD 092 is a foundational document that establishes the comprehensive framework for managing and ensuring the quality, consistency, and performance of all finishes and colors applied to Digital Equipment Corporation's products.
