3.3 Major factors which may have an impact on the development of the markets
The major factors which will influence the market for international standards developed under the auspices of TC 108 are:
・increasing internationalization of trade,
・increasing concern for the environment,
・increasing reliance on machinery, vehicles and stationary structures concern for the impact of vibration and shock on human health,
・increasing impact of machinery and structural failures on the public-at-large
・the increasing concern for public health and safety.
4. Benefits expected from the work of the ISO/TC
Technical standards produced under the auspices of TC 108 and its subcommittees directly impact public safety and the environment from the viewpoint of safer, less intrusive, higher quality dynamically designed vehicles, machines and structures. These standards will provide guidance as to the adequacy of basic design under the dynamic loads faced in daily operation and the effects of usage, time and the environment on the condition of machines and structures. The results of the TC 108 standards should help pave the way to:
・quieter and safer machines, buildings, civil structures, and vehicles,
・higher quality of life from lower exposure levels to vibration and shock
・lower environmental vibration levels e.g. saving culturally important structures
・lower noise pollution from the radiation of sound by structures.
・more reliable machines resulting from proper balancing and condition monitoring of machines
・increased life for machines and structures due to improved condition assessment, diagnostics and prognostics
・improved public health and reduction in job-related injuries due better evaluation and assessment of the effects of vibration and shock on humans
・improved public safety due to better assessment methods for the condition of structures
The photographs depicted in Figures 1 and 2 dramatically demonstrate the consequences of ignoring or poorly accounting for the dynamic forces at work in our environment. Figure 1 shows "Galloping Gertie", a bridge over the Tacoma Narrows located in the Northwest of the United States as it collapses in 1940 from a wind-excited fundamental structural bridge resonance. Figure 2 shows a cracked rotor located in a power generation plant. Fortunately, no loss of life resulted in either incident but great economic dislocation was the result.

Although these examples show two worst case scenarios, standardization of mechanical vibration and shock measurement and evaluation involve a broad range of issues pertaining to public safety, quality of life, cultural heritage, the environment and the economy. The stakes are large and the constituencies are broad and involve consumers, industry, and Government in the protection of the public interest.
The value of standardization, in general, was validated recently in a poll of engineers. When asked to name the greatest mechanical engineering achievements of the 20thcentury, a survey of 1400 engineers conducted by the American Society of Mechanical Engineers placed engineering standards and codes in the top ten. This is noteworthy especially when compared with such other life altering achievements on the list as the airplane, the automobile, Apollo spacecraft, and air conditioning to name a few. To date, ninety-two International standards have been issued under the auspices of TC 108 and over one hundred are in various stages of review.
