의미와 목적
5.1 이 테스트 방법은 느린 가열 속도를 사용하여 시편 전체에 균일한 온도를 제공합니다.. Slow heating rates are required due to low thermal conductivity of certain liquids such as paints, 수지, and related products and poor convective heat transfer in products with high viscosity. Since the sample was heated at a reduced rate, a long time interval between each determination was used to re-determine the saturation concentration of steam in the air space above the sample after each flash test.

메모 1: ISO 1523 is used in the United Nations Recommendation on the Transport of Dangerous Goods and similar regulations in the International Civil Aviation Organization (ICAO) rules and the International Maritime Dangerous Goods (IMDG) Rules. Test method D3941 is similar to ISO 1523 for use in United States Department of Transportation (USDOT) 규정. The International Civil Aviation Organization and International Maritime Dangerous Goods Rules are used for the transshipment of hazardous materials to other countries through the United States.

범위
1.1 The test method consists of the determination of the flash point of a liquid in which the sample and the air/steam mixture above it are approximately in temperature equilibrium.

1.2 This test method is limited to a temperature range of 0 to 110°C (32 to 230°F).

1.4 경고 – Mercury has been designated by many regulatory agencies as a hazardous substance that may cause serious medical problems. 수은 또는 그 증기는 건강에 해롭고 재료를 부식시키는 것으로 나타났습니다.. Be careful when handling mercury and mercury-containing products. 자세한 내용은, see the applicable Product Safety Data Sheet (SDS). It is possible for local or national laws to prohibit the sale of mercury or products containing mercury, 아니면 둘다. Users need to determine the legality of sales in their location.
