Wet film thickness is measured to determine the correct dry coating thickness.
We have no amendments or corrections for this standard. Standards Subsctiption may be the perfect solution. Your Alert Profile lists the documents that will be monitored. The teeth or notches of the gauge should be ‘dragged’ at ninety degrees through the coating and the thickness of the powder will lie between the values of the smallest tooth or notch that has powder ‘clinging’ to it and the largest tooth or notch that has no powder ‘clinging’ from it. 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.
Manufacturing and Office Location: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. If quick drying coatings are to be measured, quickly perform your measurements to avoid errors that may be caused by curing.

Measuring Powder Coatings The thickness of dry powder coatings may also be measured with these type of gauges. Please first verify your email before subscribing to alerts. Subscription pricing is determined by: Consequently, the results from the notch gage are not to be used to verify the nonvolatile content of a coating.
All the WFT gauges are highly ecomical priced. Add to Alert PDF.

Such a gage is applicable to coatings on flat substrates and to coatings on articles of various sizes and complex shapes where it is possible to get the end tabs of the gage to rest in the same plane on the substrate.
The overall size of the gauges is 2. Proceed to Checkout Continue Shopping. Examples of such items are ellipses, thin edges, and corners.
On curved surfaces such as pipes, cylinders, etc. All the other teeth or notches on the same side are of shorter lengths than the outside teeth or notches and represent different distances from the outside edge zero datum teeth.
Each gauge has eight different measurement notches. How to Use a ‘Wet Film Thickness’ Gauge Wet Film Thickness Gauges are designed to quickly and easily measure the thickness of coatings immediately after they have been applied to a substrate.
These gauges are not designed as ‘throw-away’ items and should not be compared to gauges that are ‘printed’ or silk-screened. All markings and graphics are etched and black filled.
Caltech’s wet film thickness gauge is designed to measure accurate liquid coating thickness in the easiest and fastest manner. Link v4414 Active This link will always route to the current Active version of the standard.
These gauges meet the requirements of the following International Standards: 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
If the document is revised or amended, you will be notified by email. This standard is also available to be included in Standards Subscriptions. Such a gage is applicable to coatings on flat substrates and to coatings on objects of various sizes and complex shapes. The gauges incorporate a series of notches cut into their sides much like the teeth on a comb. These gauges will survive harsh use, the graphics will not rub off even sanding the gauge will not remove the graphics, numbers, etc.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The gauges are precision manufactured from hardened grade stainless steel. Box Syracuse, E4414 U. Model A Gauges The gauges are precision manufactured from hardened grade stainless steel.
