This comparison and analysis reveals that the current direction and activity in ISO is in progress and presents logical ways of updating Korean standards in the future. Finally, the current activity of upgrading Korean standards in the Korean TC 108/SC 4 is introduced.

  • It is increasingly important to ensure that a given vibration test specification of a particular machinery component is appropriately established by considering its real environmental conditions. Vibration test standards for electrical components are well documented, for example in an IEC 60068 series, while standards for machinery components are rarely found except a few military standards. Thus many vibration tests are performed based on the military standards. However, a test based on these military standards often results in over-testing, and under-testing in some cases due to the different environmental conditions. Also, these standards require an appropriate tailoring that may not be easily accomplished. In this paper, various international and military standards are compared and investigated to obtain test specifications relevant for machinery components. Also appropriate tailoring methods are demonstrated through a case study.

  • Objective:The objective of this study is to review the exposure limits in the legislation, guidelines, and standards for human vibration in Korea. Background: There have been relatively less interests in vibration than other risk factors in Korea. However, the importance of vibration is increasing as industry and everyday life are more mechanized. Method: Various enforcements were examined including legislation, guidelines, and standards for whole-body vibration and localized vibration. Results: No exposure limits were found in legislation, guidelines, and standards for the human vibration in Korea. Conclusion: It is important to introduce new duties regarding vibration risks to the general duties. Further studies are expected on the vibration exposure limits appropriate for Korean people and job conditions. Application: The results from this study would be of help to induce more interests in human vibration to the occupational health and safety professionals of Korea.

  • The vibration sensitivities of optical cavities depending on the support area were investigated, both numerically and experimentally. We performed numerical simulations with two models: one with total constraint of the support area, and the other with only vertical constraint. An optimal support condition insensitive to the support's area could be found by numerical simulation. The support area was determined in the experiment by a Viton rubber pad. The vertical, transverse, and longitudinal vibration sensitivities were measured experimentally. The experimental result agreed with the numerical simulation of a sliding model (only vertical constraint).

  • The standards of acceptable limit and compensation is one of the most important things in environmental noise and vibration disputes resolution. In this paper, review on the present acceptable limit level and compensation standard in National Environmental Dispute Resolution Commission is introduced. Discordance of standards between in the regulation law and in the dispute resolution commission and it's improvement are discussed. Abnormal reasoning for compensation standards is pointed out from a author's private view.

  • Noise and vibration generated at construction sites become serious issues because of bigger construction projects and growing use of heavy equipment. Especially in downtown construction, noise and vibration easily exceed the legal standards that can suffer the most of surrounding residents. The number of complaints by the residents who are exposed to the noise increases as their consciousness grows. However, the Korean regulations for the construction noise and vibration only present the overall limits for target areas and times zones, and this make it difficult to take effective measures. Also in rural area, disputes between construction sites and residents arise, but the dispute resolution or taking measures are difficult because clear standards concerning cause-and-effect, estimation of effective levels, calculation of damages, and future precautions and examples lack. This paper describes legal standards regarding the noise and vibration and presents judging standards for the physical damages. This paper also introduces example public complaints that happened at Daewoo construction sites to describe the problems in the existing law and further to enable smooth construction progresses by emphasizing the seriousness of public complaints.

  • Effect of hand-transmitted vibration on human discomfort and health was reviewed. Since the effect by hand tool was more serious than those by any other vibration environments, western countries have protected hand tool workers by regulations. International organization for standardization legislate standard, ISO 5349, at 1979 for the measurement and evaluation of the effect. Afterwards, more than twenty standards on hand-arm vibration were enacted to Protect any damage of hand tool users. Even though Korea Standards adopted ISO 5349 in 2001, it is required an action plan should be applied to all of work environments, especially to the workers using pneumatic tool workwers such as miners, construction workers, and etc.
