TRIPLEX safety glass is either named TOUGHENED or LAMINATED depending on the manufacturing process, but in addition the description PLATE has been introduced after the war for laminated windscreens (initially) intended for the USA.

The date coding will be explained on basis of these three descriptions: TOUGHENED, LAMINATED and PLATE.

The "TP" or "LP" designation may refer to Triple Plate or Laminated Plate, being composed of two layers of glass with the plastic film in between to prevent break-up of the glass if it is smashed.

The term "Toughened" may refer to hardened and tempered safety glass, which is the type that breaks into a million pieces smaller then your fingernail if it is smashed.

It is indicated by the dots over the word TRIPLEX as shown at left.

This is where two dots over "T" and one dot over "X" means August.

The next two pictures have "SUNDYM" with dots under the 2nd and 6th letters, which may be 6 2=8 for the 8th year of a decade.
