6 Usage on ductwork to provide lab data about which sealants and tapes last, and which are likely to fail, research was conducted at Lawrence berkeley national Laboratory Environmental Energy technologies division. Their major conclusion was that one should not use duct tape to seal ducts (specialty tapes are available for this purpose). (They defined duct tape as any fabric-based tape with rubber adhesive.) The testing done shows that under challenging but realistic conditions, duct tapes become brittle and may fail. 7 Commonly duct tape carries no safety certifications such as ul or Proposition 65, which means the tape can violently burn, produce toxic smoke, ingestion and contact toxicity, irregular mechanical strength, and low life expectancy for the adhesive on the tape. Its use in ducts has been prohibited by the state of California 8 and by building codes in most other places in the.

Lp record and later the compact disc (CD). 5, compact Cassettes contain two miniature spools, between which the magnetically coated, 1/8" wide polyester-type plastic film (magnetic tape) is passed and wound. 6 These spools and their attendant parts are held inside a protective plastic shell which is 4"x2.5"x0.5" at its largest dimensions. Two stereo pairs of tracks (four total) or two monaural audio tracks are available on the tape; one stereo pair or one monophonic track is played or recorded when the tape is moving in one direction and the second (pair) when moving in the other. This reversal is achieved either by manually flipping the cassette, or by the machine automatically changing the direction of tape movement auto-reverse when it detects that the tape has come to an end. 7 Contents History edit before the compact Cassette edit wollensak portable reel-to-reel tape recorder Cassettes of varying tape quality and playing time.
