General Information
Cast Iron Class 6 Slotted Weights are used in a variety of applications such
as pressure, torque, and tensile strength testing. Cast Iron Class 6 Slotted
Weights are typically used with a hanger that also has its weight calibrated
so the hanger can be used as part of the overall weight under test. Several
Cast Iron Class 6 Slotted Weights may be used together to build up from a
minimum weight to a maximum test load. The hanger weight selected should be
able to accommodate the total load needed.
Tolerances
Cast Iron Slotted Weights are adjusted to ANSI/ASTM E617 Class 6. Please see
the Tolerance Chart within the Mass Standards Handbook for specific
information on the tolerance of each weight.
Construction and General Shape
Troemner's Cast Iron Slotted Weights are manufactured from a high quality
iron that meets ANSI/ASTM E617 hardness requirements. Castings also meet
ANSI/ASTM E617 surface roughness requirements and are free of cracks, pits
and sharp edges. There are adjusting cavities in each weight above 2 kg / 5
lb. Weights below 2 kg / 5 lb are adjusted by removing material from the
underside of the weight. Each weight has the nominal value cast into the
topside of the weight. Weights are protected by a durable coat of paint –
gold for metric and silver for avoirdupois – to protect the casting from
rusting. Weights 50 kg / 100 lb and above are provided with two handles on
opposite ends to aid in lifting. For dimensions of Cast Iron Grip Handle Weights, please see the dimension tables below.

Hangers
Cast Iron Slotted Weights are typically used with a hanger that also has
its weight calibrated so the hanger can be used as part of the overall weight
under test. Weight hangers are available in a variety of lengths and weight
capacities. Hangers are calibrated to a mass value, and also have a capacity
of how much weight can be loaded onto them. The length of each hanger is
listed in the Ordering Tables below. To determine which hanger will
accommodate your weights, use the stem height of the hanger as the maximum
height, then use the thickness dimension of each weight along with the
quantity you intend to place on the hanger to determine the total height of
your stack of weights. The height of your stack of weights should be less
than the length of the hanger. The dimension of the hook opening is 1/2
inch.
Surface Finish
All surfaces shall be smooth and free of scratches, dents and pores as
outlined in ANSI/ASTM E617. Paint will be hard and resistant to chipping.
Color codings (gold for metric and silver for avoirdupois) shall be used to
differentiate the weights. For ANSI/ASTM E617 surface finish specifications
see the Mass Standards Handbook on the web site.
Ordering a Certificate With Your Weight or Weight Set
The following certificates are available to meet your traceability and
compliance needs. Complete information on our calibration certificates and
samples of certificates are located in the Mass Calibration and Certificate
Options section of the web site.
