| Troemner Alloy 8 Stainless Steel Precision Weights | |
| Troemner Alloy 8 Stainless Steel OIML Precision Weights | |
Troemner Alloy 8 Stainless Steel Precision Metric Weights are available in Troemner UltraClass, and ANSI/ASTM E617 Classes 0, 1, 2, 3 and 4. Troemner Alloy 8 Stainless Steel Precision Avoirdupois Weights are available in ANSI/ASTM E617 Classes 1, 2, 3, and 4. ANSI/ASTM Class weights meet or exceed specifications as defined in the ANSI/ASTM E617 standard. The weights are manufactured of the finest stainless steels available including Troemner Alloy 8 Stainless Steel, which was developed by Troemner and is available exclusively through Troemner. This unique material possesses low magnetic susceptibility, uniform consistency and high resistance to corrosion. It is the finest grade of stainless steel available and is similar to material originally specified in the manufacture of state primary standards.
Weight specifications are designed so the specifications on surface finish, markings, construction, material density and magnetic properties get more restrictive as the weight tolerances get smaller in order to enable the weight to maintain its tolerance over time. These weights are designed for your most demanding weighing applications.
**Caution** Class 0 weights have extremely small tolerances and are intended to be used as primary reference standards with direct traceability to national reference standards. They should be used in extremely stable environments and handled with the highest level of care. Otherwise, due to their one-piece design, Class 0 weights will not maintain their measured value within the tolerance class. One may be tempted to purchase the weights with the tightest tolerances in order to reduce measurement uncertainty. However, frequency of use, care, handling and environmental conditions all play a major role in the long term stability of weights and these factors should be considered before purchasing Class 0 weights.
Why UltraClass?
Troemner
UltraClass weights are the most precise two-piece weights available
with weight tolerances 50% greater than ANSI/ASTM E617 Class 1 tolerances.
Troemner UltraClass weights combine high precision with the advantage
of two-piece construction (1g and larger) avoiding costly replacement
issues associated with one-piece weights.
Suggested
Applications
Class 0 weights are intended to be used in metrology laboratories
where the stability of the environment and careful handling are
assured. Although very stable, one-piece construction Class 0 weights
have no method of adjustment and are not suitable for general laboratory
use.
Troemner UltraClass
weights can be also be used as reference standards as well as calibrating
Class I balances as specified in OIML R 76. Troemner UltraClass
weights can also be used to calibrate Class 1 weights.
Class 1 weights
can be used to calibrate certain Class I and Class II balances and
scales as specified in OIML R 76. Class 1 weights can also be used
to calibrate Class 2 weights.
Class 2 weights
can be used to calibrate weighing instruments for important commercial
transactions like gold and precious stones. They can also be used
to calibrate Class 3 weights.
Class 3 weights
can be used for calibrating balances with moderate precision, with
a readability as low as 0.1 g to 0.01 g.
Class 4 weights
can be used for calibration of semi-analytical balances and for
student use.
Ordering

| NVLAP Weight Calibration Certificate | NVLAP
Weight Calibration Certificate is a detailed, multi-page weight
certificate designed to meet all of your ISO (including ISO/IEC
17025), FDA, GMP, GLP, DOD, ANSI/NCSL Z540-1, and nuclear requirements.
The NIST-administered National Voluntary Laboratory Accreditation
Program (NVLAP Lab Code 105013-0) approves all procedures for
this detailed weight certificate. The measurement process follows
the recommendations of NIST Handbook 145. |
|
| Traceable Weight Certificate | Traceable
Weight Certificate - designed for those laboratories and companies
that require traceability, but do not need to meet any stringent
regulatory requirements. In contrast to NVLAP or UKAS calibration
procedures, the Traceable Weight Certificate measurement process
is based on a single standard and utilizes one series of comparisons. |
|
| Statement of Accuracy | New
weights and weight sets supplied without weight certificates
come with Troemner's Statement of Accuracy which provides the
nominal value, type of weight, material / density and weight
class. Note: There is no NIST traceability supplied with
this statement. The Statement of Accuracy is not suitable for
quality or regulatory requirements. Troemner's Statement of
Accuracy is only available with the purchase of new weights.
Troemner's Brass Weights are not supplied with a Statement of
Accuracy. |
