NKKK conducts sampling, quality determination and other survey and measuring of raw materials for iron production.For a mechanical sampler or other sampling instrument newly equipped or remodeled in a plant, we carry out accuracy-check by the client's requirements.NKKK participates in the Sampling Committee of Japan Iron and Steel Federation, JIS/ISO-TC102 Iron Ore Committee and in the Sampling Committee of Center for Coal Utilization, Japan, JIS/ISO-TC27 Coal and Coke Committee. We cooperate in establishing the Japanese Industrial Standard as an expert member of the Sampling Method Committee and of Analysis Committee of iron ore, coal and coke, and other materials. Both committees belong to the Industrial Science & Technology Policy and Environment Bureau of the Ministry of Economy, Trade and Industry of Japan.
The items surveyed and measured by the Association cover the following:
- Iron ore, iron ore pellet, iron sand
- Coal and coke
- Ferroalloy, pig iron
- Steel scrap
- Fluorspar (metallurgical grade)
Inspection and Measuring of Raw Materials of Non-ferrous Metals
Non-ferrous metals include a wide scope of materials ranging from copper, lead, zinc, nickel, chrome, manganese and bauxite in the form of ores, concentrates, semi-products or alloys.
NKKK undertakes consistent supervision from unloading to analysis.
NKKK participates in the Sampling and the Analysis Committees of Japan Mining Industry Association, JIS/ISO-TC183 as a member of Domestic Committee directed by the Industrial Science & Technology Policy and Environment Bureau of the Ministry of Economy, Trade and Industry of Japan.
