Abstract

DIN 680:2008-02 defines standardised dimensions, tolerances and naming conventions for windowed envelopes used for business mail. It covers envelope formats (C-series related to document and insert formats), window shape and placement, recommended window material and finishing details (for example corner rounding and backing), and requirements for envelopes intended for machine insertion. The standard references related DIN documents that specify paper sizes, business-letter formats and envelope constructions.

Scope

This standard specifies the outer formats, allowable limit dimensions, window sizes and exact window positions for window envelopes (Fensterbriefhüllen) in forms U (envelopes) and T (mailing bags) that are intended to receive business letters and documents according to the relevant business-letter formats. It applies to envelopes intended for manual and machine insertion and gives requirements for window backing, window transparency, and edge finishing where relevant to postal handling and automated processing.

Key topics and requirements

• Standard envelope formats tied to ISO/DIN paper sizes (C-series) and folding/insert forms (Form A / Form B).
• Precise window dimensions and positional coordinates relative to the envelope edges (including limit and nominal dimensions).
• Designation and naming convention for window envelopes (e.g., "U C4 B", "T C4 A").
• Material and workmanship requirements for the window patch: transparent, non-reflective, dimensionally stable under humidity, and well-bonded.
• Recommendations on window corner rounding and adhesives consistent with machine processing and postal requirements.
• Requirements for envelopes intended for mechanised insertion in accordance with DIN 678-2 and related machine-handling specifications.
• Normative references and cross-references to related DIN standards for paper sizes, business-letter layout and envelope construction.

Typical use and users

Manufacturers of envelopes and window patch materials, paper converters, print houses and stationery suppliers use this standard to design and produce window envelopes compatible with business-letter formats and postal/machine handling. Postal operators, office-systems manufacturers (filing and inserting machines), procurement teams and standards committees consult DIN 680 when specifying envelope products for business mail and automated mailing systems.
