Chai&an announced that Committee's draft specifications for carburetor and diesel fells have
been accepted. The specified sulfur con e t or not more than 1% in the case of carburetor
fuel cannot be (adhered to with respect to tar distillation plants. Since it would it .
be economical for these plants to lower ne 3 'content, since the necessary sulfuric acid
uspnotsbe obtaineAL, and since the quality would be lowered by too sisrp refirarig. WHAt'iiith
the boiling characteristics and octane rating (68, CFR, motor method), the spec was changed
to 5 content not over 2% for gasolines from tar distillation. Cetane no for diesel fuel
is 40, minimum .

for compensation)can be used.

readily available to interested persons in the GDR. It is therefore necessary that thb:
western business office of the Kammer der Technik supply final drafts (of standards) and tha
the DIN's for the GDR be published, for example, in "Chemische Technik". This polies is

In discussions of full qualities, it is noted that several firms using diesel fuel tales comp eine(
about filter stoppages and corrosion. Fault apparently lies in mixing synthextic wish tar-
distillation product. Not clear whether cokipg or corrosion caused stoppages. Com;Laints on
