Perforations

Standard Perforation Reference Codes

SAS International manufactures a series of standard perforation patterns. To aid your specification each pattern has a reference code.

For example D1505.

  • The first letter references the pitch of the perforation pattern, either: S (square pitch) or D (diagonal pitch)
  • The first two numerals reference the size of the hole
  • The second two numerals reference the open free area as a percentage

For example, D1505 = Diagonal pitch, 1.5mm hole, 5% free area.
