When it comes to evaluating particle residues remaining on parts after manufacturing, the “go to” is often particle counting. Particles remaining on parts after normal manufacturing operations are collected using a secondary, more aggressive washing method. Collected particles are then tallied by size, number and, in some cases, type and probable origin as a measure …

In a very early blog written in 2011 I talked about the “Scotch” tape test for cleanliness. At that time I did not address quantification of the results other than as a visual assessment. In addition to evaluating general cleanliness, this technique is being found particularly applicable when determining the cleanliness of substrates that “shed” …

As I was writing the recent post about gravimetric Millipore testing it occurred to me that I was trying to boil a good-sized part of a 180+ page document into 500 or so words. It also occurred to me that many people don’t have the time for or interest in reading endless pages of specifications …

Millipore testing is all about evaluating cleanliness based on the presence of particles or other solid, non-soluble contaminants. In general, it can not be used to detect the presence of hydrocarbons or other contaminants which will be solubilized in the extraction process. The results of Millipore testing are generally expressed by weight using gravimetric analysis …

“Millipore” testing evaluates cleanliness by extracting particulate contamination from a surface and then either weighing or counting and quantifying the collected particles to assess the cleanliness achieved by a prior cleaning means. The first step in either case is to collect and prepare for analysis any particulate residue remaining on the surface after pervious cleaning. …

Once in a while a question comes up that I can’t think my way through. Here is one. Within an insulated system there is air passing over a heat source that constantly produces a certain number of BTU’s per hour. In the process, the air is heated from the inlet temperature to an elevated temperature …

It would make sense that variations in the aluminum foil used for testing in the foil test for ultrasonic performance could have a bearing on the outcome of the test. Most people use standard “grocery store” aluminum foil for testing because it is inexpensive and widely available. So let’s talk about that first. The most …

I just spent a couple of hours re-reading several of the ISO specifications related to “Millipore” testing including ISO16232-3 and -7. I put the word Millipore in quotes here because although these are normally called Millipore specifications, none of them mentions the word Millipore. (Millipore happens to be the name of a company that developed …

After three + months of sheltering in place, things are slowly returning to the “new normal” here in New York state which is where I write this blog. We all know all too well what’s been going on around the world over the past several months so I’m not going to belabor those details here. …

In and around your structure, you will find a wide scope of sorts of deck – from hard stone floors, for instance, marble and rock to solid wood and overlay flooring, terminated tiles, concrete, terrazzo or even basalt (which begins from magma and is presumably the hardest sort of ground surface). All floor remaking errands should, thusly, start with a thorough examination of the zone – allowing the surface material creation and any issues to be recognized. This will ensure the correct thought and approach is applied to achieve the perfect last item.
The three key groupings are polyurethane, water based and dissolvable. Poly makes the most grounded and most enduring covering yet has an unquestionable holding up fragrance and can in like manner be somewhat noxious. Dissolvable based thing are strong yet can similarly be exceptionally noxious, which implies they ought to be applied particularly in all around ventilated locales. Water-based things are for the most part the more earth welcoming yet can be less effective.
A couple of things are multi-reason, while others have explicit remedial properties. For example, they may have been uncommonly characterized to manage unequivocal sorts of risks, for instance, oil stains or mixture sprinkles. This is significant in regions, for instance, parking spaces and dissemination focuses, where a wide grouping of materials and liquids will come into contact with the deck. By making sensitive balance over its surface, slip safe sealers or finishing things can in like manner improve prosperity in vivaciously managed zones.
It is an inclination that puts aside exertion to learn, with significant experience being gotten from each completed movement. It is basic to scan for a totally qualified capable while looking through a transitory laborer to do the organization.
