This standard is not included in any packages. Caltech’s wet film thickness gauge is designed to measure accurate liquid coating thickness in the easiest and fastest manner. These gauges meet the requirements of the following Xstm Standards: Need more than one copy?
ASTM D – 95() Standard Practice for Measurement of Wet Film Thickness by Notch Gages
Examples of such items are ellipses, thin edges, and adtm. Such a gage is applicable to coatings on flat substrates and to coatings on objects of various sizes and complex shapes. Caltech Engineering Services offer disposable plastic wft gauge is designed for once only use, simply place in the wet paint note the wet paint thickness, Allow paint to dry and retain for future ISO record or customer d44144.
Teeth or notches are machined into the sides of the gauge. The substrate surface may also be examined for ‘drag’ marks left c4414 the teeth or notches to confirm the values read from the notches or teeth. If the document is revised or amended, you will be notified by email.
The values given in parentheses are for information only.
Your Alert Profile lists the documents that will be monitored. Model A Gauges The gauges are precision manufactured from hardened grade stainless steel. The overall size of the gauges is 2.
Already Subscribed to this document. Wait several seconds to allow the teeth or notches of the gauge to become ‘wetted’ by the coating, then withdraw the gauge vertically keeping it at ninety degrees to the substrate.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
See asstm drawing below. The wet film thickness of most organic coatings including paints, resins, lacquers, varnishes, gel coat, etc. The gauge may now be read to determine the wet film thickness. Correction of the c4414 after it has dried or chemically cured requires costly extra labor time, may lead to contamination of the film, and may introduce problems of adhesion and integrity of the coating system.
If quick drying coatings are to be measured, quickly perform atm measurements to avoid errors that may be caused by curing. Most protective and high performance coatings are applied to meet a requirement or specification for dry film thickness for each coat or for the completed coating system, or for both. Proceed to Checkout Continue Shopping. This standard is also available to be included in Standards Subscriptions. WFT Gauge can also be used to measure powder coating thickness before it goes through curing.
The gauges are precision manufactured from hardened grade stainless steel. The mode of operation is similar to measuring ‘wet’ coatings.
The values given in parentheses are for information only. Please first log in with a verified email before subscribing to alerts. The ends of the teeth or notches are visually examined, some will be coated or ‘wet’ and some will not be coated or ‘wet’.
Standard ASTM D4414
Place the wet film thickness gauge at ninety degrees to the coated substrate and penetrate the surface of the coating with the notched or toothed side of the gauge until the substrate is firmly contacted. Add to Alert PDF. Also notched gages can be very useful in the shop and field for determining the approximate thickness of wet films over commercial articles where size s and shape s are not suitable for measurements by other types of gages.
