Tatisteheff bJBJkCTi Asbestos -- Substitution of Other Rhodesian Chrysotil* Qrades fbr Grades C * G Id accordance with our proala* ut th* neeting of th* Opera ting Coanlttse of th* Conblnod Raw Material* Board yesterday, I aa happy to givd you th* following lnforaatioo whlsh you will no doubt wlah to paaa on to th* Ministry of Supply. C U/3 and C * G/4 Although sAppftea pf tb*s* grad*a appear aapl* both l'or th* United States and th* United Klngdas, th* War Production Board arranged last fall to have .10 tons osoh of VRA/3 and VRA/4 sent to th* United States for axperiaental purposes. Our aanufaotur*rs evaluated th*s* fibers and round than to be taloy and not *quiva lent to th* C * 0 grades, and stated that they would not us* then under any eireuastenees. In r*sp*ot to HVL/3 and Wih/iXX, our aanufaoturers founa that they w*r* not *ntlr*iy sultabl* for th*ir is*. On* aanuractur* agreed to tak* 50% HVL/3 in th* plao* of C * 0/3, but h* had no us* whatsoever for HVI/3XX. In th* spring of 1*43 th* War Production Board arranged ror a >napl of VRA/2. This fiber was very carefully axaalded by th* principal user of C * 0/2 In this oountry. Very careful tests were aade, and it was found that th* shrinkage as received, after crush ing and after opening, was considerably in excess of C a 0/2. 1b* card shrinkage, as wall as th* eere roving waste, was alaost aoubie, and to* tonsils strength wqs about bO% less* The War Production Board reels that in an snergenoy this fiber night be used as a sifestltute for C a U/2, but its value under any test, whether laboratory or production is' decidecuy less.  /* As regards HVl/2, manufacturer in this country endeavored to obtain a sample for test. I quota froa a lsttar rseolvad by ths War Production Board from this manufacturer. "As X mentioned to you whan t tha nesting on Friday, September 2$, Tumar 4 Navail aay proauoa soaa HVL/2 froa tha Havelock Kina, which aay ba usad in part as a substitute for C4G #2. They were going to experiment with this fibre and assess tha value of tha grads, and after tha production of HVl/2 becomes standardised, they will, no doubt, sand us a sample so wa can try it in our mill. "Vie received this information froa Ur. Shephard, of Tumar 4 Newell, during ths letter part of August, and on Septeaber 21, received a letter froa thea stating that supplies ox HVL/2 are "likely to oontinue, for soaa considerable tips, to suffer froa surface contamination, la feel sura that you will not wish to rsoslve any material which is not up to proper standard aad representative pf opettatpus supplies. Is therefore propose to leave tha order on our books for coeplsticn ss soon as ths position at our Ulnes makes this possible. This being so, t^e consignment will be invoiced at ths pries ruling -it date of shipment. "Is shall, no aoubt, rtoeive additional information from Turner 4 Newell as ths year progresses, end will keep you advised as soon as ws find out that this is a usable fibre in our production." The War Production Board states that until Turner 4 Newell see fit to eend these samples, tests can not be performed, but that as soon as ths samples of HVL/2 are aubm tted they will make .-itain that thee* are thoroughly tested by users in the Jnited Slates. cct Ur.
