GB/T 10358-2008Oilseed residues -- Determination of moisture and volatile matter content (English PDF)

Foreword

This standard is identical with ISO 771. 1977 "Determination of oilseed moisture and volatile matter content" (in English).

For ease of use, this standard made the following editorial changes.

--- "This International Standard" be replaced by "this standard";

"." --- With a decimal point instead of a comma as the decimal point, "";

--- Delete international standards foreword.

This standard is GB/T 10358-1989 "oilseed moisture and volatile matter determination," the amendment.

This standard compared with GB/T 10358-1989 main changes are as follows.

--- Added "normative references", "Notes" and "Test Report", etc;

--- Increased the result of the determination of the claim;

--- Regulate the use of the expression values, quantities and units.

From the date of implementation of this standard instead of GB/T 10358-1989.

The standard proposed by the National Food Authority.

This standard by the National Standardization Technical Committee OILS.

This standard is mainly drafted by. People's Republic of China Hubei Exit Inspection and Quarantine.
