Not every lab offers ISO 17025 accredited calibration services, so what are the benefits of working with one? And how do you know if the lab you are using is an ISO 17025-accredited calibration lab? Is compliance the same thing as accreditation? These questions were answered in a recent interview with Bill Hirt of ACLASS Accreditation Services. Continue reading
The accuracy of electronic devices naturally drifts over time due to use, stress, vibration, and other factors. While it is possible to minimize the change in your test equipment, it is impossible to eliminate drift completely. That is exactly why electronic test equipment calibration must be done at regular intervals as defined by the manufacturer or as you have defined based on the historical accuracy of your device.
Torque wrench calibration has a large effective on total cost of ownership. Using a tool that has fallen out of calibration can result in costly repairs and warranty costs as well as unhappy customers. Calibrating your torque wrench too frequently can result in paying for services when it may not truly be needed. So, how can you know when to send it in for service?
Depending on your industry, your application, and the environment in which your meter operates, you may require flow meter calibration and maintenance more, or less, frequently than others. While calibration drift can be caused by many factors such as the flow meter type and the environment in which it operates, here are some of the most common reasons for calibration to drift; some of which you can avoid, others that you can’t.
Accuracy is important in any application that utilizes flow meter technology. But in some industries it is absolutely critical that your flow meter accuracy is just that, accurate. In applications where products are sold or purchased on the basis of a meter reading, it is highly important to make sure you know exactly how much liquid is flowing to protect your bottom line. Here are a few ways improper flow meter calibration can cost you money. Continue reading
We’ve been talking a lot lately about the various costs and factors that must be considered when thinking about on-site vs. off-site aircraft jack proof load testing. So what is the final verdict? There is no right or wrong answer, so it’s up to you to decide. To help you along, we have taken all of the topics we covered on the blog and put them into a single chart that provides a general comparison of the typical costs associated with both off-site and on-site aircraft jack proof load testing.
We’ve talked about a number of costs that factor into the overall process of aircraft jack proof load testing such as shipping, down time, etc. But how much does the testing service itself actually cost? That depends on whether you’re working with the original jack manufacturer or a third party service provider. Continue reading
Whether you’re talking about an axle jack or a tripod jack, hydualic aircraft jack proof load testing leaves you without an important part of your aircraft maintenance tool kit until service has been completed. How long will you be down a jack? That depends on whether you’re shipping the jack out for testing or having on-site proof load testing provided.
Shipping your jacks and having them tested and repaired can leave your facility without one of your most vital maintenance tools for months. Consider this:
Your airplane jack was designed to withstand certain amounts of force, but there are many reasons this may no longer be the case. To ensure proper function, airplane jack load testing is a must; but it’s not cheap. Shipping fees alone can be costly and that’s not even taking into consideration the “sweat equity” that goes into prepping the jack for shipping and putting it back into use upon its return. That is why, rather than going through the time and expense of shipping a jack out, many facilities opt for on-site proof load testing instead.
As mentioned in our previous article about the pros and cons of on-site vs. off-site proof load testing services, shipping a hydraulic aircraft jack can be very expensive. The cost of shipping will vary depending on factors such as distance, jack type, and shipping service provider. In our experience, many companies wind up expediting shipping to reduce down time which can further add to the price. Keeping the variables in mind, let’s consider the cost of shipping an axle jack from your facility to the manufacturer or third party testing facility. Continue reading
When it comes to having your aircraft jacks proof load tested, where do you turn? Most maintenance facilities will ship the jack back to the original manufacturer or send it to a third party testing and repair shop. The down side to both of these options though is the overall investment of both time and money, especially for those facilities with multiple aircraft jacks that require attention. To avoid the inconvenience and cost of shipping the jacks out for testing, some facilities will call a company who can provide on-site proof load testing which can be a hassle-free and more affordable; but that does not mean it is the best option in every situation. Here’s how to decide which option is right for you.
For any company who relies on flow meters, the topic of flow meter calibration is nothing new. But the importance of regular calibration goes far beyond complying with government or industry regulations in order to avoid costly fines. In fact, there are many ways irregular or improper flow meter calibration can cost you.
As mentioned in previous hydrualic aircraft jack maintenance articles, manufacturers recommend 90 day maintenance and testing be done on your jack(s) once every 12 months. Testing may also be advised outside of the regular schedule if an event takes places that could potentially damage the jack. For example, being dropped or having something dropped on the jack that may cause damage to the structure or the hydraulic system. Below is an example of maintenance and aircraft jack proof load testing guidelines recommend by most hydrualic aircraft jack manufacturers.
There is no way to tell if your hydraulic aircraft jack can withstand the force it was built to withstand until it’s too late. This can create a lot of problems when you think about it. For example, what if you lift a plane up on the jack and as you’re working on it, the jack leaks. Now it may not have the power you need to get the plane back on the ground safely.
There are many factors that can impact the performance of your hydraulic aircraft jack, but the most common issues have to do with leaks in the hydraulic system.
(CHARDON, OHIO) September 23, 2015 – e2b calibration, an ISO/IEC 17205 accredited calibration and repair laboratory in Northeast Ohio, today announced the availability of their newly published white paper titled, “Aircraft Maintenance Guide to Hydraulic Jack Proof Load Testing and Maintenance Best Practices.”
