TITLE: FMVSS INTERPRETATION

TEXT: Thank you for your letters of January 16, 1969, and February 3, 1969, concerning safety glazing in motor vehicles.

Referring to your request to use marking as described in the second paragraph of your letter, I believe you have confused the two-digit manufacturer's code number specified in Docket 23 with the model number specified in Section 6 of USASI Standard 226.1-1965.

Federal Motor Vehicle Safety Standard No. 205, Glazing Materials incorporates USASI Standard 226.1-1955 by reference. Marking of the glazing materials must comply with Section 6, Marking of Safety Glazing Materials. Included in this marking is the requirement for a model number related to a detailed description of a specific glazing material. The example,(Illegible Word), is a model number assigned by you in accordance with foot note #24 at the bottom of page 29 of(Illegible Word) Standard 226.1-1986.

The two-digit manufacturer's code number that follows the "LOT" symbol is used, at the option of the glass manufacturer, as an alternative method of complying with that certification requirements specified in Standard No. 205. This "DOT" symbol followed by a two-digit manufacturer's code number should be added to the marking you should in your letter.

Following are my answers to the questions asked in your letters

Question (1) Must we add the symbol "DOT" somewhere in the above marking"?

Question (2) Can you agree with the proposed marking without taking into consideration that our clear laminated M.I.B glass has been approved, or are was compelled to submit our coloured glass to a laboratory and ask for a new approval?

Question (3) If you extend our AS.1-M.11 approval to the said AS3-26 type, as we hope, is this extension valid for all the American States, including those affiliated to the A.A.M.V.A.? If so, do you advise all the States of this extension or shall we do it?

Answer to Question (1) Only if you wish to avail yourself of the alternative method of certification specified in Standard No. 205 Amendment (33 P2 14152).

Answer to Questions (2) and (3) The approval of glazing materials to which you refer is a State approval independent of the U.S. Federal government. Those questions should be directed to the individual States or A.A.N.V.A. for answer.

I am taking the liberty of assigning a two-digit manufacturer's code number to your company on the assumption that you wish to avail yourself of the alternative method of certification.

Splintex Balge S.A. is assigned number 24. This number should appear after the characters "DOT" when you certify your glazing materials by the alternative means published in the Federal Register, Vol. 33, No. 183 - Thursday, September 19, 1968, (enclosed).

I am sorry for the delay in answering your initial letter.

Sincerely,

Enclosure

Gentlemen,

We are manufacturers of safety glass, namely for the automobile industry, and have had several safety glass types approved, the last ones being:

1/4" mm thick H.I. laminated: Splintex Gilly HI/AS1-M11.

7/32" mm thick H.I. laminated: Splintex Gilly HI/AS1-M12.

We supply a constructor of busses with laminated glass pieces placed along edges of the roof, as shown on the attached picture. This laminated glass is 1/4" thick and is composed of a H.I. interlayer but also two coloured ones with finally just 2 light transmittance. We have in hand information you sent to our customer (Title 23 - Chapter II/Dockets n degree 23 and 29 - Notice(Illegible Word) May we beg you, on this ground, if we may use, for the described glass, an AS3-28 marking with a two digit code number, for example M15; if so, our marking would be

SPLINTEX Height in accordance with U.S.A.S.I.

GILLY Height in accordance with U.S.A.S.I.

AS.3-26-M.15 requirements.

LAMINATED

Our other questions are:

1) Must we add the symbol "DOT" somewhere in the above marking?

2) Can you agree with the proposed marking without more, taking in consideration that our clear laminated H.I. 1/4" glass has been approved, or are we compelled to submit our coloured glass to a laboratory and ask for a new approval?

3) If you extend our AS.1-M.11 approval to the said AS3-26 type, as we hope, is this extension valid for all the American States including those affiliated to the A.A.M.V.A.? If so, do you advise all the States of this extension or shall we do it?

As this is a very important and urgent question, we beg you for a prompt air-mail answer and hope you will give us full details about the other steps we should have to undertake.

Awaiting your kind news and thanking you beforehand for all your help, we remain, Gentlemen,

Very truly yours.
