A Story from the Testing Lab: What is 100% on the TAPPI Brightness Scale?

The first paper brightness tester utilizing directional geometry, the GE Reflection Meter, was developed and introduced to the Pulp and Paper Industry in the early 1930's.  Because of the difficulty of producing instrument which agreed with each other within the limits of visual discrimination, the Institute of Paper Chemistry (Appleton, WI) established a "Brightness Standardization System" whereby all newly manufactured brightness testers were matched geometrically, photometrically and spectrally to a master instrument. 

The basis for the 100% brightness point was magnesium oxide. This was chosen since it was the 'whitest' substance available at the time. Since magnesium oxide was very unstable and yellows over a relatively short period of time, more stable opal glass and paper standards were used to transfer this calibration from magnesium oxide to the instruments.  Therefore, calibrated opal glass and paper standards were issued on a monthly subscription basis to allow brightness tester users to maintain close agreement with the IPC master.

TAPPI Test Method T452, which was based on the GE Reflection Meter, was adopted by TAPPI in 1948.  Subsequently, brightness testers conforming to TAPPI T452 have been manufactured by Martin Sweets Company, Diano Corporation and Technidyne Corporation.

A Story from the Testing Lab: Preventative Maintenance

Technidyne has offered Preventative Maintenance (PM) on its instruments since 1985.  This is similar to routine maintenance on your car to make sure it runs well and for years to come.  During a PM visit the instrument 'current' state is checked, the instrument has routine maintenance performed (cleaning, checking voltages, etc.). Finally, the instrument is calibrated and rechecked for its 'as left' data.  Also, during PM visits general maintenance questions can be asked and features can be demonstrated. 

A customer skipped their annual PM visit which made them a non-active PM customer.  Six months later a primary instrument went down on Saturday morning with no backup instrument on-site.  Active PM Customers receive loaner equipment at no charge.  Since they were no longer an active PM customer they had to rent the loaner and pay a higher repair costs.  PM is normally performed during a scheduled trip which includes multiple customers who can then share these costs.  Also, PM customers get reduced rates on parts and labor for repairs.  By skipping this one visit ended up costing this customer an additional $4,500 for the loaner and repair.   

By skipping the normal PM, this customer paid for the repair and loaner.  The additional cost would have paid for PM on all of their instruments that year and could have prevented the failure which cost them even more time and money.

Contact our Service Department for more information on the most economical approach to maintaining your equipment.

Agent for Mexico Updates Training

Saul Calderon of INASII S.A. DE C.V. (INGENIERA ASESORIA Y SERVICIOS DE INSTRUMENTACION IDUSTRIAL), Technidyne's exclusive sales and service agent in Mexico, was in for updated training this week.

Mr. Calderon received the latest training techniques on classic Technidyne instruments like the Micro S-5, Color Touch 2, Color Touch PC.  He also received information and training on many new products that will be released to the Pulp and Paper Industry in the coming months.

Technidyne and INASII have worked together for a number of years.  INASII also represents IGT, Testprint, AVS, emtec and AFG instrumentation.  They also provide service and preventative maintenance on a variety of other equipment including Lorentzen & Wettre.

A Story from the Testing Lab: Calibration Standards

Many years ago we received a typical phone call from a customer that was struggling to get their 10-year-old brightness tester to calibrate. We talked them through the calibration procedure. They seemed to understand the steps and process. They calibrated, check linearity and translucency. When they went to check the calibration it was not right. We talked them through diagnostics looking at lamp voltage. They had a spare lamp. So, they installed it and refocused the new lamp. Calibration was still off. Finally, they checked the different voltages on the instrument, but this did not give us the solution to the calibration problem.  Throughout all of this, the customer insisted that we needed to visit the site and get this rectified.

We scheduled the trip and sent a technician to the site. They were armed with all sorts of tools, parts, calibration standards and strategies to allow them to attack this problem instrument head on.  Upon arriving at the facility, the technician sat with the instrument and read the set of calibration standards they had brought with them. The calibration was even farther off than the customer had indicated.  The technician calibrated the instrument with the new standards and checked the calibration for linearity and translucency. The instrument was in perfect calibration.

After this was completed the technician asked the customer to see the calibration standards they had been using. The customer went to a drawer in the testing lab and removed a set of paper calibration standards from an envelope. She explained that they had carefully cared for the standards since they came with the instrument OVER 10 YEARS AGO.

It was obvious to the technician that the paper calibration standards had yellowed and become frayed over the 10 years of use. Those calibration standards were no longer usable.

The Paper Industry has a unique, but extremely reliable calibration process and hierarchy. This is based on using paper calibration standards as a transfer standard from the Master instruments. However, since the standards are paper, they will age and require replacement on occasion. The life of the standards is based on how well the standards are maintained (see TAPPI T 1219 Storage of paper samples for optical measurements and color matching). Subscriptions are available on a monthly or quarterly basis.
