For anyone looking to upgrade their test lab or quality-assurance facilities, NPE 2003 had plenty to offer. The show saw the debut of instruments and software for color measurement and a wide assortment of parts-inspection systems. Also showcased in Chicago were the latest instruments and software for testing a wide variety of end-use performance properties.
Color and appearance
New color instruments were plentiful, as was software that uses the internet to assist compounders and color users in specifying, communicating, and formulating color digitally and in real time. For example, X-Rite now offers an Internet module for its Color-Master quality-assurance and formulation software. Companies with many locations using the company’s instruments can access a single database via the web, even though the software is installed on a server at only one location.
As reported previously (E-Collaboration Is Coming [But More Slowly Than Expected]), new web-enabled software from GretagMacbeth provides “virtual calibration” so that different makes and models of instruments measure color to the same standards.
Both X-Rite and GretagMacbeth also unveiled new instruments. The Premier 8000 Series high-performance benchtop spectrophotometers from X-Rite are said to be the first to capture a digital image of a sample that can be viewed on a computer monitor before the instrument takes color measurements. These units can also measure samples in both vertical and horizontal orientations and are said to have excellent inter-instrument agreement.
GretagMacbeth’s new Color i 5, a sphere-based laboratory benchtop, is a mid-range system ($14,500) comparable in features to higher-end instruments (see Web-Enabled Color Measurement Harmonizes Different Instruments).
Datacolor introduced what’s said to be the industry’s first spectrophotometer designed to accurately measure metallic and pearlescent pigments as well as the new generation of diffraction-based special-effect pigments. Its MultiFX10 spectrophotometer measures these pigments at multiple angles because they look different when viewed from various perspectives. Datacolor also brought out a new line of laboratory-grade spectrophotometers (SF600X, SF450X, SF350X) in a range of prices and capabilities (see Three New Models of Lab Color Instruments).
Two new portable gloss meters (Micro-Gloss and Micro-Tri-Gloss) from Byk-Gardner have self-diagnostics that check the calibration values (see Portable Gloss Meters for Faster QC). And Minolta’s new pair of hand-held colorimeters (CR-400 and CR-410) have detachable, lightweight measuring heads (see Portable Colorimeters Fit in One Hand).
PocketSpec Technologies made its debut in this market with its $350 battery-powered, hand-held ColorQA color measurement device. It has a probe with an electro-optic sensor that permits quick quality checks of the color of molded parts (see Hand-Held Instrument for Quick Color QC).
DVT Corp. brought out what it calls the industry’s first ma chine-vision sensors with a built-in spectrophotometer for enhanced color recognition. SpectroCam is de signed for QC applications where small color variations are critical, such as auto interior parts.
For on-line color measurement and QC of products such as PVC profiles and films, X-Rite offers the new Teleflash spectrophotometer system. Measuring distance can be up to 5 ft, and the system tolerates small variations in measuring distance from sensor to sample. The system also has thermochromism compensation for color differences related to product temperature. That allows for color measurement without waiting for the product to cool and stabilize.

New mechanical testers
Two companies introduced new pendulum impact testers that can use either a Charpy or Izod configuration. Tinius Olsen showed its new Model IT 503 impact tester, which does not require changing the pendulum to perform the two tests. Instead, the operator attaches the appropriate striking “tup” on the pendulum and the proper specimen clamp or anvils on the base of the unit. The aerodynamically designed compound pendulum is said to give this tester maximum rigidity in the direction of the impact and to virtually eliminate any windage losses. A “low blow” feature provides an easy and reliable way to release the pendulum from a lower-than-usual height, allowing for testing at lower impact velocities and energy levels.
The Advanced Pendulum Impact device is Dynisco Polymer Test’s first Izod and Charpy impact tester. It is said to offer high rigidity and a pendulum arm with low-friction precision bearings—features that reportedly improve accuracy by avoiding unwanted energy dissipation. PLC control and menu-driven software are said to provide easy operation. It sells in the range of $25,000 to $35,000.
Com-Ten Industries’ new ball-screw-driven 700 Series variable-speed Universal materials testers have increased speed ranges. They can perform compression and tensile tests without the need for special adapters or cages.
Also new from Com-Ten is C-TAP Version 2 data-acquisition software, which includes more built-in formulas, ability to plot multiple tests on one chart, and a report-formatting wizard.
Com-Ten also offers the new ComTouch controller for automated test systems. It automatically detects sample failure and can return the tester to its original position. It measures force, deflection, and speed and can report peak or break results.
A new automatic notcher that handles up to 50 specimens is available from Ceast USA. Its Automatic Notchvis Plus utilizes a special cutting motion that reportedly reduces the friction and induced stress generated by traditional rotary notchers. Precision motor control lets you set a notch depth with resolution of 0.01 mm.
Rheological &thermal properties

The Ci series weather testers are approved by Ford Motor Co. and General Motors Corp. for conducting SAE J1885 and J1960 testing on interior and exterior automotive materials. These units reportedly use the latest water-cooled xenon-arc lamps to deliver consistent amounts of radiant exposure. Easily interchangeable glass filters tailor the light spectrum to match sunlight conditions in particular end-use environments. The new controls have increased memory and a library of standard and user-defined test programs.
Dynisco’s new LME lab mixing extruder is designed to extrude test samples from very small amounts of non-PVC developmental materials. Instead of a screw, the benchtop unit has a smooth, conical, heated rotor that processes just 5 to 10 g/hr. It sells for $10,000 to $12,000.
Dynisco also launched the LMM lab mixing molder, which uses the same plasticating rotor as the LME, but feeds the melt to a hand-operated compression mold for producing test-sample disks. This benchtop unit costs $10,000 to 12,000.
