The sealing cavity can be used to adjust the total weight. Painted cast iron weight has a chip-resistant paint that is corrosion-resistant and conforms to NIST Handbook 105-1 standards. A sealable adjusting cavity allows the weight to be fractionally adjusted to meet individual specifications. The weight meets NIST Class F specification 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.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. ## Features - Metric and U.S. customary grip-handle test weight for testing field standards and industrial devices - Painted cast iron weight has chip-resistant paint that resists corrosion and conforms to NIST Handbook 105-1 standard - Sealable adjusting cavity for adjusting total weight - Meets National Institute of Standards and Technology (NIST) Class F specification for commercial "Legal-for-Trade" weighing operations ## Images ![Rice Lake 12817 Cast Iron Painted Grip Handle Test Weight, 100kg Mass, NIST Class F - Image 1](https://m.media-amazon.com/images/I/91vtZfhW0HL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ YES, these are excellent, extremely accurate weights. NO, they are not Certified. *by R***Z on Reviewed in the United States on January 16, 2018* I have 2 Rice Lake Weights and 1 Troemner. The Rice Lake seems to be better quality. 1 of my Rice Lake weights is NIST certified(the ones sold here are NOT certified.) The 10KG that I purchased is amazingly accurate, certified at 10.0000217kg. Crazy accurate. I will buy more of these for sure. The surface of the weights is quite good on Rice Lake, but it's cast iron so expect a rough texture. ### ⭐⭐⭐⭐⭐ These things are a great implement for strength training *by G***T on Reviewed in the United States on August 14, 2018* I purchased these scale weights to work on various grip and strength training exercises. By using magnets and smaller weight plates, I can increase the overall weight to accommodate different exercises. I am very happy with these. ### ⭐⭐⭐⭐⭐ Accurate weight! *by J***Y on Reviewed in the United States on December 15, 2017* Calibrated my scale so my ebay package weights are within 0.2 oz of post office scale readings. ☺ (And that tiny discrepancy is probably because my floor isn't perfectly level or due to vibrations from my furnace.) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/103404505-rice-lake-12817-cast-iron-painted-grip-handle-test-weight](https://www.desertcart.pt/products/103404505-rice-lake-12817-cast-iron-painted-grip-handle-test-weight) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-22*
