Standard Test Method for Burning Quality of Kerosene
SIGNIFICANCE AND USE
5.1 Since the information provided by this test method is largely qualitative in nature, specific limits covering the following characteristics are required in referring to this test method in specifications for kerosene:
5.1.1 Duration of the test: 16 h is understood, if not otherwise specified;
5.1.2 Permissible change in flame shape and dimensions during the test;
5.1.3 Description of the acceptable appearance of the chimney deposit.
SCOPE
1.1 This test method covers the qualitative determination of the burning properties of kerosene to be used for illuminating purposes. (Warning—Combustible. Vapor harmful.)
Note 1: The corresponding Energy Institute (IP) test method is IP 10 which features a quantitative evaluation of the wick-char-forming tendencies of the kerosene, whereas Test Method D187 features a qualitative performance evaluation of the kerosene. Both test methods subject the kerosene to somewhat more severe operating conditions than would be experienced in typical designated applications.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific warning statements appear throughout the test method.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

However, kerosinekerosene burning tests can be conducted in any part of a room that is adequately ventilated and reasonably free
of drafts. When necessary, the test lamp should be surrounded with a suitable circular shield to protect from drafts. The circular
shield is to be constructed of draft-proof material of about 600 mm 600 mm diameter and height.

quantity of a given bulk product tank, batch, shipment, and so forth, at the time and place of sampling.

9.2 Thus, the sampling procedures employed are to ensure initial procurement of a representative sample and also preclude
subsequent contamination or deterioration of the sample during handling prior to testing. To this end, kerosinekerosene samples
for burning quality testing are to be obtained and handled in strict accordance with Practice
