Overview
ISO 3883:1977 - Office machines: Line and character capacity of address masters is an early International Standard that defines minimum capacities for address masters (address plates/supports) used in addressing systems for office machines. Published in 1977, it was a first attempt to rationalize the variety of address-master capacities used by postal, mailing and office-equipment systems worldwide.
Key topics and requirements
- Scope: Specifies the minimum line and character capacity required for address masters used with office machines and addressing systems.
- Minimum capacities (technical requirements):
- Lines per master: Not less than six lines of text.
- Line pitch: 4.233 mm (1/6 in) line pitch.
- Characters per line: Not less than 30 characters per line.
- Character pitch: 2.54 mm (0.10 in) character pitch.
- Purpose: To provide a baseline dimensional and capacity requirement for address plates, helping manufacturers and users achieve consistency across different addressing equipment.
- Context: Developed by ISO/TC 95 (Office machines) as a first-step standard toward rationalization of address-master dimensions and capacities.
Applications
ISO 3883:1977 is useful for:
- Manufacturers of address plates, address masters and office mailing equipment who need to design components compatible with common addressing systems.
- Engineers and designers of automated addressing, mailing, and labeling machines specifying minimum address-master dimensions for reliable operation.
- Procurement teams and specification writers who include standards-based requirements in tenders and purchasing documents for postal and office machinery.
- Mailing houses and postal operators seeking interoperability between address masters, printers and inserters.
- Standards committees and technical documentation authors referencing historical or baseline requirements for address formats.
Practical value
- Ensures interoperability between addressing devices and address plates by prescribing minimum line and character capacity.
- Simplifies equipment design decisions when selecting address-master sizes for new machines or retrofits.
- Provides a clear baseline for legacy systems maintenance and for aligning older equipment with standardized addressing dimensions.
