About Rice Lake 12504 20 Piece Stainless Steel
The Rice Lake metric, stainless steel test weight set meets National Institute of Standards and Technology (NIST) Class F specifications, and is designed for calibrating other weights, or electronic balances and scales. The weight set is constructed of stainless steel for stability, resistance to corrosion, and low magnetic susceptibility. The weight meets NIST Class F specifications for commercial "Legal-for-Trade" weighing operations often required by state and local weights and measures officials, device installers and service technicians. Class F weights can be used to test the accuracy of most Class III scales, all scales of Class III L or IIII, and scales not marked with a class designation. NIST Class F weights are manufactured to specifications of NIST HB-105-1. The set of 20 weights includes two each 20g, 2g, 200mg, 20mg, and 2mg weights, and one each 50g, 10g, 5g, 1g, 500mg, 100mg, 50mg, 10mg, 5mg, and 1mg weight, tweezers, and a protective case. Calibration weights are used to measure the weight or mass of an object using a balance or scale, or to calibrate other weights or instruments. Calibration weights can be certified or uncertified. Certified weights meet strict guidelines for accuracy and can usually be recertified. Certified weights are used in labs where a high degree of accuracy and repeatability is required. Uncertified weights are used where a lower degree of accuracy is required, including student laboratories, rough weighting operations, and measuring force. Hooked and slotted weights are often used to measure pressure, torque, and tensile strength, and to demonstrate basic laws of physics. Calibration weights differ from lab weights, which are general purpose weights used to hold an object in place, similar to a paperweight. Science education products incorporate applied math and science principles into classroom projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology. Rice Lake Weighing Systems manufactures weight-related and process-control equipment for use in research, scientific, and quality control labs. The company, which was founded in 1946 and is headquartered in Rice Lake, WI, meets International Organization for Standardization (ISO) 9001:2008 standards, and is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) to ISO/IEC 17025:2005.
