의미와 목적
5.1 인화점 측정 통제된 실험실 조건에서 열 및 발화원에 대한 샘플 반응. It is only one of many characteristics to be considered when assessing the overall flammability hazard of a material.

5.2 Flash points are used by government regulators in transportation and safety regulations to define and classify flammable and combustible materials. For a precise definition of these classes, see the specific regulations involved.

5.3 Flash points can indicate the possible presence of highly volatile and flammable impurities or contaminants in a given liquid, such as the presence of residual solvents in solvent refined dry oils.

5.4 These balanced flash point test methods use smaller specimens (2 밀리리터) and shorter test times (1 분) compared to conventional non-equilibrium test methods such as test Method D56 and Test Method D93.

5.5 Test method D3828, Test method D8174 and ISO 3679 are similar test methods and use the same equipment.

범위
1.1 These test methods include procedures to determine whether A material flashes at a specified temperature when using a small closed cup device (flash/no flash method A) or to determine the minimum finite temperature at which the material flashes (방법 B). The test method is applicable to paints, enamels, lacquers, 광택, solvents and related products with flash points between 0°C and 110°C (32°F and 230°F) and viscosity below 15 000 mm 2/ 두번째 (cSt) ~에 25 ℃ (77 °F).

메모 1: Tests can be performed at higher or lower temperatures, but the accuracy has not been determined.

메모 2: More viscous materials can be tested according to Appendix A4.

메모 3: Organic peroxides can be tested in accordance with Appendix A5, which describes the applicable safety precautions.

메모 4: The United States Department of Labor (OSHA, Hazard Communications), the United States Department of Transportation (RSPA) and the United States Environmental Protection Agency (EPA) have designated test method D3278 as one of several acceptable methods for determining the flash point of liquids in their regulations.

1.2 SI 단위로 표현된 값은 표준값으로 간주되어야 합니다.. The values given in parentheses following SI units are for reference only and are not considered standard values.

1.3 This standard is used to measure and describe the reaction of materials, products or components to heat and flame under controlled conditions, but does not in itself contain all the factors required for fire hazard or fire risk assessment of materials, products or components under actual fire conditions.

1.4 이 표준은 모든 안전 문제를 다루기 위한 것이 아닙니다., 만약에 어떠한, 그 사용과 관련된. 적절한 안전을 확립하는 것은 이 표준 사용자의 책임입니다., 건강 및 환경 관행을 확인하고 사용 전 규제 제한의 적용 여부를 결정합니다..

1.5 본 국제 표준은 국제 표준 개발 원칙에 관한 결정에서 확립된 국제적으로 인정받는 표준화 원칙에 따라 개발되었습니다., 세계무역기구(WTO) 무역기술장벽위원회가 발행한 지침 및 권고사항.
