x1558. To Hs{Lord Ernest Hives - Chair}/Mr. Lidsey. HLL/AG.12.12.33. Laboratory Report No. L2900 Re: Viscosity Tests. We send herewith viscosity curves and cold test figures for the samples of oil submitted. Any viscosity figure quoted exceeding 2000 seconds cannot be regarded as accurate. In order that we may quote figures in the range 30°C to -10°C. we are obtaining another viscometer. We will therefore, supply you with such figures in due course. Hl. AC | ||
