1. Scope
1.1 This test method covers the determination by Tag Open-Cup Apparatus of the flash point and fire point of liquids having flash points between −18 and 165°C (0 and 325°F) and fire points up to 325°F. 1.2 This test method, when applied to paints and resin solutions that tend to skin over or that are very viscous, gives less reproducible results than when applied to solvents. N OTE 1—In order to conserve time and sample, the fire point of a material may be determined by the Tag Open-Cup Method by continuing the heating of the specimen to its fire point. Fire points may also be determined by Test Method D92, which should be used for fire points beyond the scope of this test method. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 This standard should be used to measure and describe the properties ofmaterials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk ofmaterials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements ofa fire risk assessment which takes into account all ofthe factors pertinent to an assessment ofthe fire hazard ofa particular end use. 1.5 Warning—Mercury has been designated by many regu- latory agencies as a hazardous material that can cause central nervous system, kidney and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Safety Data Sheet (SDS) for details and EPA’s website, http://www.epa.gov/ mercury/faq.htm, for additional information. Users should be aware that selling mercury and/or mercury containing prod- ucts into your state or country may be prohibited by law.1.6 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 appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.7 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
8. Assembly and Preparation of Apparatus
8.1 Place the tester in a level position on a solid table free of vibration, in a location free of perceptible draft, and in a dim light. Maintain a room temperature of 24 6 3°C (75 6 5°F) throughout the test. Other room temperatures may be specified on agreement between buyer and seller. N OTE 2—For materials with vapors or products of pyrolysis that are objectionable, it is permissible to place the apparatus with shield in a fume hood with the ventilation turned off. The ventilation can then be turned on at completion of the test, or when and if fumes become objectionable. 8.2 Adjust the horizontal and vertical positions of the taper so that the jet passes on the circumference of a circle having a radius of at least 6 in. (150 mm). The jet should pass across the center of the cup at right angles to a diameter passing through the thermometer and in a plane 1 ⁄ 8 in. (3.2 mm) above the upper edge of the cup as measured from the center of the orifice. 8.3 Using the leveling device as a gage, adjust the height of the taper so that the center of the orifice is exactly 1 ⁄ 8 in. (3.2 mm) above the top edge of the glass cup when it is in place. It is imperative that this adjustment be made as accurately as possible. Raising or lowering the taper can be achieved by bending it slightly or preferably by adding and removing thin metal shims as required from between the taper and the vertical supporting member of the swivel holder. 8.4 With the glass cup in place in the bath, adjust the thermometer holder so that the thermometer is supported firmly in a vertical position halfway between the center and edge of the cup and on a line passing through the center of the cup and the pivot of the taper. Place the thermometer so that the bottom of the bulb is 1 ⁄ 4 in. (6.4 mm) from the inner bottom of the cup. 8.5 Set the draft shield around the tester so that the sides form right angles with each other and the tester is well toward the back of the shield.
