What is OIML?
OIML (International Organization of Legal Metrology) has standardized the measurements in world trade. Other significant organizations like The International Bureau of Weights and Measures (BIPM) and International Organization for Standardization (ISO) recommend OIML.
The relevance of OIML test weights in weighing solutions.
- OIML certified test weights are ideal for regular balance testing carried in labs and production.
- OIML test weights are known for their distinct features such as being robust, durable and having adjusting cavity.
- There are several classes of these weights. They are E1, E2, F1, F2, M1, M2 and M3. All the products of these classes meet the requirements of OIML.
ASTM
ASTM (American Society for Testing and Materials) has systematically arranged the required standards in calibration and measurement. ASTM standards are accepted and are followed in several states of U.S.A.
The relevance of ASTM test weights in weighing solutions.
- ASTM certified test weights offer low magnetic permeability and high corrosion resistance.
- While the sizes of these weights range from 1mg to 2kg, there are available in 1-4 classes.
- ASTM test weights are bound to maintain the standards prescribed by ASTM.
What do OIML and ASTM standards mean to the companies around the world?
- Any business is run with the virtue of trust. The trust factor becomes vital as it can make or break businesses.
- Since it is widely accepted that the OIML and ASTM certified products perform better, reputed companies opt to provide these products.
- When it comes to testing weights, there are manufacturers available in every corner of the world. However, the trust factor is balanced between the buyers and sellers using OIML and ASTM certified products.
- Both OIML and ASTM are now regarded as the benchmark of quality all over the world.
Hi-Weigh
With its footprint in food processing, lab solutions, livestock farming, transport, medical and supermarket fields, Hi-Weigh touts as being one stop for purchasing. This Shanghai-based firm promises easy shipment facilities. Above all, Hi-Weigh offers OIML and ASTM certified test weights. Being an organisation that specailizes in weighing systems, it is improving constantly to meet ever-growing needs for standard weights.
The test weights offered by Hi-Weigh are as follows:
- SSE2 E2 S.S Test Weight: This test weight is made using stainless steel and belongs to class E2 and has a capacity of 1mg-20Kg. It has a density of 7.96g/cm3 and contains magnetization of ≤8μt. Along with the necessary accessories, this weight set is packaged in an aluminium box. Not limiting to the same model, Hi-Weigh offers other models in the same series.
- SSF1 F1 Class Precision Weights: Manufactured for calibration of balances and scales, these F1 class weights are available in the OIML and ASTM classes. Its prominent features include a density of 7.9g/cm3, Magnetization of ≤25μt and a standard capacity of 1mg-20Kg.
- SSB OIML F1 Class Heavy Capacity Test Weight: Heavy capacity test weights are manufactured in capacities of 50kg, 100kg, 200kg, 500kg, and 1000kg. Available in OIML F1 class, these test weights hold magnetization of ≤25μt.
- SSF2 F2 Class Precision Calibration Weights: Offered in OIML and ASTM classes, SSF2 Precision Calibration Weights come in various models and capacities. Its features include density of 7.9g/cm3, the magnetization of ≤80μt.
- SSB F2 Class Heavy Capacity Test Weight: These robust test weights are manufactured in capacities of 50kg, 100kg, 200kg, 500kg, and 1000kg. Consumers can opt for either OIML or ASTM class test weights in this category. The F2 test weights have a magnetization of is ≤80μt and density of 7.9g/cm3.
- SSM1 M1 Class Precision Knob Weights: These knob weights are designed by Hi-Weigh to meet the standards requires in industrial scales and balances. While its magnetization is ≤250μt, these knob weights are of 7.9g/cm3 density.
Along with class S test weights, Hi-Weigh offers the below products:
- IWS Cast Iron Grip Handle Weight: Cast steel material goes into the process of manufacturing these OIML standard shaped weights. Having a capacity range of 5kg-20kg, these M1 class handle weights promise high quality and performance.
- IW M1-M2 Class Cast Iron Test Weight: These iron weights come packed with an additional 500kg crate and are processed into a smooth surface. The capacity of these iron weights ranges from 1kg to 20kg. While meeting the standards of OIML, they are designed for calibration of industrial scales.
The reason for the growing use of OIML and ASTM certified test weights should be obvious by now. Only proved quality and performance can keep the worldwide trade alive and kicking.
