摘要:

AbstractA new Intermediate Scale Heat Release Rate Test Method is being developed primarily for testing assemblies in the vertical mode. Using the oxygen consumption calorimetry methodology and exhaust collection systems that already exist in many laboratories in the US and around the world, the apparatus is very economical to install. The sample size lends itself to reptitive testing in a short period of time. Sample preparation is generally quick and easy. Further development of the method should progress now that the method has been introduced at ASTM and will be introduced formally into ISO in the near future. There has been a favorable response by several laboratories who are considering construction of the apparatus. Additional assemblies tests are already underway and additional data will be presented in the near future.

摘要:

AbstractThis paper outlines the flammability test methods and requirements for electric cables specified in some Japanese standards. Only two different methods of a small‐scale flame test as specified in Clause 28 of JIS C 3005 are applied to electric cables for general use, and whether or not the flammability test should be conducted and which method should be adopted depends on the type of cables, both of which are specified in each separate standard. Cables for electrical equipment of ships have to pass another small‐scale flame test as prescribed in Section 6.7 of JIS C 3410. A flame test method for flame‐retardant telecommunication cables has been introduced in JIS C 3521. This specifies a vertical open tray flame test on grouped cables, almost in accordance with IEEE Standard 383. In addition to the method for a vertical open tray flame test, one for a vertical closed duct flame test on grouped cables is also specified in a Japanese Cable Makers' Association Standard, i.e. JCS 366. Some flame‐retardance requirements for electric cables in Japan are listed and di

摘要:

AbstractIn the study of smoke suppressants the measurement of gross amount of smoke from a given sample is essential. However, smoke being a complex phenomenon, its measurement with optical methods presents practical problems. The paper describes a flow system for the measurement of smoke production. Effectiveness of smoke‐suppressant formulations for poly(vinyl chloride) as assessed in a flow system is reported. Results of experiments conducted to probe and establish the capability of smoke measurement in a flow system using a helium–neon laser are discus

摘要:

AbstractThis paper reports an experimental study on the physical properties of a sprinkler water spray. The mass flux density, shape of spray pattern, size distribution and velocity of water droplets discharged from two types of 15 mm orifice sprinkler heads were measured. Three operating flow conditions of the sprinkler system, including one specified for the Ordinary Hazard class under the LPC rules for sprinkler design, were set. The sprinkler head was installed above finished floor levels of either 2 m or 2.2 m. The median droplet size was found to be related to the water pressure and the orifice diameter of the sprinkler head as proposed by Dundas. The droplet size distribution function can be fitted by a Rosin–Rammler functio

摘要:

AbstractA small‐scale enclosure was constructed for characterizing the contribution of interior finish wall‐lining materials to fire growth in compartments. The enclosure was based upon refinements to a design devised by scientists at the National Institute for Standards and Technology for quarter‐scale modelling of room fire tests on interior‐finish materials. A large volume of evidence is presented demonstrating how this small‐scale enclosure could provide the information about surface flammability, heat release, smoke generation and contribution to fire growth that is required for a reasonable assessment of the fire performance of interior wall‐finis
