適用范圍：This test method measures the color of clear liquids. It is applicable only to materials whose color-producing bodies have light-absorption characteristics similar to those of the platinum cobalt color standards used. (See Test Method D 1209 and Note 1.) The values stated in SI units are to be regarded as the standard. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazards statements see 7.1 and Note 2. Note 1 -Although this test method and ISO 6271-1997 differ in some details, data obtained using either are technically equivalent.
