General Information
Troemner ANSI/ASTM Class 5 Calibration Weights are designed for routine scale and balance calibration where moderate accuracy is required. Class 5 weights are a practical choice for general-purpose calibration, quality control, production environments, and routine testing of industrial or commercial weighing equipment.
Class 5 weights provide reliable accuracy for applications that do not require the tighter tolerances of Class 0, Class 1, Class 2, Class 3, or Class 4 weights. They are well suited for everyday scale verification, maintenance checks, and field calibration where durability and practical handling are important.
As weight classes increase numerically, the allowable tolerance generally becomes larger. Class 5 weights are therefore not intended for high-precision analytical balance calibration, but they are commonly used for routine scale testing and calibration.
Why Class 5?
ANSI/ASTM Class 5 weights offer a balance between accuracy, durability, and cost. They are commonly used when a scale or balance needs to be checked regularly, but the application does not require laboratory-level reference standards.
Class 5 weights are useful for testing bench scales, counting scales, shipping scales, platform scales, receiving scales, production scales, and other moderate-accuracy weighing instruments. They are often selected for industrial facilities, warehouses, shipping departments, food processing, manufacturing, quality control departments, and service technicians.
Tolerance Class
ANSI/ASTM Class 5 weights have larger tolerances than Classes 0 through 4. This makes them better suited for routine calibration and scale checking rather than high-precision laboratory reference work.
For exact tolerances by denomination, refer to the applicable ANSI/ASTM E617 tolerance chart or the Troemner Mass Standards Handbook. Tolerance requirements vary by nominal weight value and class.
Construction and General Shape
Troemner Class 5 calibration weights are available in a variety of styles depending on the weight size and application. Smaller weights may be supplied in cylindrical, flat, or sheet-metal style designs, while larger weights may be supplied in grip-handle, slotted, hanger, or heavy-capacity designs.
The construction of the weight depends on the specific model, nominal value, and product style. Many Class 5 weights are designed for convenient handling in routine calibration environments. Larger weights may include handles, slots, or lifting features to make placement on the scale easier and safer.
Class 5 weights are typically marked with their nominal value for easy identification. Markings, finish, adjustment method, and construction style may vary depending on the specific weight design.
Surface Finish
Class 5 weights are manufactured to meet the applicable ANSI/ASTM E617 requirements for their class. Surface finish requirements for Class 5 are less restrictive than higher-precision reference classes, but the weights are still designed to provide dependable performance for routine calibration and testing.
Depending on the model, Class 5 weights may be supplied in stainless steel, cast iron, or other suitable materials designed for scale calibration use. Material and finish should be selected based on the environment, frequency of use, and scale capacity.
Suggested Applications
Class 5 weights are recommended for general scale calibration and routine testing applications, including:
- Bench scales
- Platform scales
- Shipping and receiving scales
- Counting scales
- Production scales
- Industrial scales
- Warehouse scales
- Quality control checks
- Field service calibration
- Routine scale verification
Class 5 weights are especially useful where the scale readability and accuracy requirements do not justify the use of tighter-tolerance Class 1, Class 2, Class 3, or Class 4 weights.
Material Specifications
Material selection for Class 5 weights depends on the specific weight style and capacity. Smaller precision-style Class 5 weights may be made from stainless steel, while larger test weights may be available in cast iron or other durable materials suitable for industrial scale testing.
When choosing Class 5 weights, consider the following:
- Scale capacity
- Scale readability
- Required tolerance
- Frequency of use
- Handling method
- Environment
- Need for a certificate of calibration
- Storage and protection requirements
Certificates
Troemner Class 5 weights may be available with calibration certificates depending on the specific part number and configuration. A certificate provides documentation of the measured value and traceability, which is important for quality systems, audits, and calibration programs.
For regulated environments or formal calibration programs, select the appropriate certificate option at the time of purchase.
Presentation
Troemner weight sets are typically supplied in protective cases or storage boxes depending on the size and configuration of the set. Individual weights may or may not include a case, depending on the model.
Protective cases help keep weights organized, clean, and protected from damage when not in use. Proper handling and storage help maintain the accuracy and long-term stability of the weights.
Caution: Weight cases are not intended to be used as shipping containers. When sending weights out for calibration, the weights and cases should be overpacked in a larger protective carton or shipping container to prevent damage during transit.
Summary
Troemner ANSI/ASTM Class 5 Calibration Weights are ideal for routine scale calibration, general testing, and industrial weighing applications. They provide dependable accuracy for everyday use while offering a more economical option than higher-precision calibration weight classes.
Class 5 weights are a good choice for users who need reliable calibration tools for moderate-accuracy weighing equipment.
