(CONTINUATION of explanations to Norm DIN 476)
PADS, INDEX CARDS, BOOKLETS
With tear-off pads and duplicate-books, the pages detached must be in
norm size, so the pad or duplicate-book will be taller or wider than the
norm.
Index cards without tabs are in exact norm sizes (A4, A5, A6, A?). Index
cards with tabs are larger by the size of the tab.
Boaklets. wallets. and files are naturally wider than the norm-format sheets
to be inserted in them. Their sizes should as far as possible be chosen from
the four ranges.
FURTHER AIMS FOR NORM FORMATS
Since for some special purposes no norm sizes are yet fixed, the ranges A
to D define limits for norms for (for example) sheets of paper. envelopes,
office furniture. type areas. printing stock sizes. etc. The aim for these cir
cumstances is to establish special norms later.
NORM FORMATS ABROAD

tries: Switzerland, Austria, Hungary, Czechoslovakia, Holland, and Belgium.
