There are increasing developments and uses of sorptive building materials for the reduction of indoor air pollutants and odors, and test method for reduction performance of them has been required. For formaldehyde reduction performance test of those materials, JIS A 1905 was established Feb 2007, and Feb. 2008 JIS A 1906 was for VOCs. Our group has developed the air flow control unit for small chambers in order to evaluate reduction performance of sorptive building materials. JIS A 1905 explains the two methods (Part.1-constant concentration supplying method and Part.2-emission material method) for reduction performance test, but differences of test methods might provide different result values even if the same material was tested. In this paper, when changed area ratios (i.e. loading factor) of specimens under the same test method, it was investigated what differences would be made in performance values. As a result, sorption flux showed different values by differences of area ratios, but did nominal and steady values under the same area conditions. When the same sorptive material was tested, reduction performance values gained from JIS A 1905-1 showed approximately three times higher scores in compared with JIS A 1905-2.

Recently, there are increasing developments and uses of sorptive and degradation building materials, and test method for reduction performance of them is being required. For reduction performance test of those materials, JIS A 1905-1, 2 were established Feb. 2007, but ISO and KS is not yet. Our group has developed the air flow control unit for 20L small chamber to evaluate reduction performance of sorptive building materials. JIS A 1905 explains the two methods (Part. 1 and Part.2) for reduction performance test, but differences in methods might provide different result values, even if the same material was investigated. In addition, when changed area ratios (i.e, loading factor) of specimens under the same test method, it was examined what differences would be made in performance values. As a result, when changed area ratios of specimens, sorption flux showed different values but equivalent ventilation rate did nominal and steady values. When the same sorptive material tested, reduction performance values gained from constant concentration supplying method (JIS A 1905-1) showed approximately two times higher scores in compared with emission material method (JIS A 1905-2).

For emission tests from adhesives, glass or SUS plates have been generally used as a base material. Applied on a glass plate, due to the fast hardening and decay of volatile chemicals, it is difficult to assure the uniform quality for specimens preparing and curing, which would deteriorate the test repeatability. Our research group has made the concept of a more appropriate and effective method for emission test on adhesives and suggested the specimen using the calcium silicate (SiCaO3) board (CSB) as the base material substituted for glass or SUS plate. This paper would include 1) VOCs emission tests of CSB itself to decide a base material substituting for glass and SUS plates, 2) Test repeatability with new CSB specimens, and 3) VOCs emission tests from four kinds of adhesives. As results, undesired contaminants from CSB itself were not detected or little if any. Extension of emission decay time and improvement of test repeatability were confirmed in comparison to the glass plate specimens. The differences in emission property over test period were observed respectively depending on adhesive type.

In Korea, the small chamber method complying with KS (Korean Standard) M ISO 16000-9, ISO 16000-9 and JIS A 1901 is usually used for emission test from building materials. Recently, there are increasing develpment and use of sorptive and degradation building materials, and test method of reduction performance of them is being required. In Japan, JIS A 1905-1, 2 was established Feb. 2007, but ISO and KS is not yet. Our group has developed the air flow control unit for 20L small chamber to evaluate reduction perfomance of sorptive building materials. Chamber performance was verified through measuring the air velocity near the surface of the test specimen and mass transfer coefficient when using the newly developed unit. At the end of this paper, chamber test results of two types of sorptive building materials were stated.

Japan established the Small-chamber method (JIS A1901) in 2003. This method can measure to determine the emission of volatile organic compounds and aldehydes for building products. But, Semi Volatile Organic Compounds (SVOC) cannot be measured by JIS A 1901 method because of low volatility and high boiling point. Accordingly, in 2008, the determination of the emission of semi volatile organic compounds for building products was established in Japan. On the other hand, this chemical material contained in various building products as plasticizers and flame retardants, and this material causes negative effects for the human body. According to the study of house dust in Sweden, concentration of DEHP and BBzP in house dust was associated with doctor-diagnosed rhinitis and asthma. Phthalate ester tends to adhere to house dust, measurement of concentration of Phthalate ester in house dust was needed. Specially, Korea houses were used very much polyvinyl sheet as floor products and floor heating system. Therefore, this study investigated concentration of Phthalate ester in house dusts in Korea. As a results, all investigated house dusts of Korea were higher concentration of DEHP in house dust than the 50 Percentile in Germany. Some house dusts of Korea were showed higher than the 95 Percentile in Germany.
