Why Mechanization? The mechanization ensures precision in operation, time reduction, labour saving and reduction of drudgery associated with various farm operations as also economize the utilization of inputs and thereby harnessing the potential of available resources. If mechanization is necessary, what are the priorities?
Protocol for Testing of Agricultural Machinery. Farm machinery testing involves the determination of:. Functional performance characteristics of machine. Power requirement of a particular component of whole machine. Wear testing of some of soil engaging tools. External forces such as soil forces acting on soil engaging tools, and. Stresses developed in different parts of machine due to static or dynamic loading. Farm machinery manufacturers are very much concerned to know the above details about their products.
Tests conducted by various state and central agencies and institutions involve the functional performance tests, power measurement, durability test, wear test and forces acting on tillage tools. Proper planning and careful execution of tests is extremely important.
Wherever feasible, tests may be designed to permit statistical analysis of results to accelerate durability tests in the laboratory and functional tests in the field.
Testing of farm machines is useful to both buyers i. Testing encourages improvement in quality and functional suitability.
Testing of machines helps farmers in proper selection of implement, suitable power source and required adjustments in machines. It helps manufacturers in commercial publicity of product, better design and sales promotion. Comparable data for similar machines is available to manufacturers, which help them in improving the design of their product. Different countries have established various organizations and institutions, which test the farm equipment, supplied by the manufacturers and submit the confidential reports.
The foremost duties of such organizations are to first develop the standard test codes for different types of farm machines, which forms the basis for testing of the machines. Government of India has established Bureau of Indian Standards, which does the job of preparing standard test codes. Bureau of Indian Standards, Manak Bhavan, 9 Bahadur Shah Zafar Marg, New Delhi has develop standard codes for agricultural tractors and power tillers, agricultural produce processing equipment, crop production equipment, farm transport equipment, forestry and plantation crop machinery, harvesting and threshing equipment, horticultural equipment, soil working equipment and sowing, fertilizer and manure application equipment.
International Organization for Standardization ISO was formed in with headquarter at Geneva, Switzerland to promote the development of standardization and related activities with a view to facilitate international exchange of goods and services and to develop cooperation in the share of intellectual, scientific, technological and economic activities.
In all following six standards were issued:. Site news.

Беккер молчал. - Ja. Дверь слегка приоткрылась, и на него уставилось круглое немецкое лицо. Дэвид приветливо улыбнулся. Он не знал, как зовут этого человека.
- Халохот улыбнулся. - Может считать себя покойником. И он задвигал крошечными металлическими контактами на кончиках пальцев, стремясь как можно быстрее сообщить американским заказчикам хорошую новость. Скоро, подумал он, совсем .
Сьюзан не оставляло подозрение, что в компьютере шефа кроется нечто, чему в один прекрасный день суждено изменить весь мир. Да, я была с ним слишком сурова, - подумала Сьюзан. Ее мысли были прерваны внезапным звуковым сигналом входной двери Третьего узла.
- Она вздохнула. - Быть может, придется ждать, пока Дэвид не найдет копию Танкадо. Стратмор посмотрел на нее неодобрительно.
Яростная волна гнева захлестнула. Она снова услышала голос Дэвида: Я люблю. Беги.
