The TQC Bresle Patch is used to test surfaces in accordance with ISO 8502-6 and ISO 8502-9, which specify tests using TQC Bresle Patches as the Bresle Method of extracting the soluble salts from the test surfaces. The TQC Bresle Patch from the TQC Bresle KIT is adhered to the test surface and distilled water is pumped into the Bresle Patch using a syringe. The water is flushed between the TQC Bresle Patch and the substrate, which causes the soluble salts on the test surface to be dissolved into the water.

Important with this Bresle Method is that all distilled water with dilluted salts is retrieved from the Patches. Obviousely any leakage of the solution from the TQC Bresle Patch during pumping and flushing will cause the final result, that is measured with a conductivity gauge, to be inaccurate. Therefore the ISO 8502-6 Bresle Method states that the Patch must be able to resist a certain amount of inflation without leaking the dilluted salt solution.

Other inaccuracy issues may arrise when Patches are contaminated during production by using inferior materials or because of contaminated production facilities. The TQC Bresle Patch is garanteed free from any contamination as all patches are made of high class materials that are washed prior to manufacturing and produced in a contamination free production facility. All TQC Bresle Patches come with a declaration of conformity and an ISO 17025 accredited test laboratory certificate can be supplied on request.

TQC Bresle Patches are supplied with the TQC Bresle KIT - Chloride Test KIT and replacement patches can be purchased for use with existing TQC Bresle KIT's

The TQC Bresle Kit - Chloride Test Kit includes all the necessary equipment for assessing the level of soluble salts on blast-cleaned surfaces prior to coating. The TQC Bresle Kit - Chloride Test Kit is complying with the ISO 8502-6 that describes the a method of extracting, for analysis, soluble contaminants from a surface by use of flexible cells in the form of adhesive bresle patches or Bresle sampler, which can be attached to any surface, regardless of its shape and its orientation. The method described is suitable for use in the field to determine the presence of soluble contaminants before painting or a similar treatment. Inside the TQC Bresle Kit - Chloride Test Kit is a conductivity gauge used for the assessment of soluble salt ions as chlorides, sulphates and nitrates. The Bresle Method described in the ISO 8502-6 and ISO 8502-9 standard, states that the conductivity is mainly directly proportional to the concentration of dissolved chloride ions in the solution.

Contamination of blast-media:
The TQC Bresle Kit - Chloride Test Kit can also be used to determine the contamination of blast-media in use. A too high level of salts in the recycled abrasive media or water can re-contaminate the surface being cleaned. Two standards ISO 11127-6 and ISO 11127-7 describe the determination of water-soluble contaminants by conductivity measurement and the determination of water-soluble chlorides.

Scope of supply:
TQC Digital conductivity meter, 25x TQC Bresle Patch, 6x 25ml beaker, 200ml distilled water, 20ml syringe with needle, 2,5ml syringe with needle, bresle are mask magnet, bresle test instruction sticker, calibration and rinse solution.......

Ford viscosity cup is a simple gravity device that permits the timed flow of a known volume of liquid passing through an orifice located at the bottom.

Under ideal conditions, this rate of flow would be proportional to the kinematic viscosity (expressed in stokes and centistokes) that is dependent upon the specific gravity of the draining liquid.However, the conditions in a simple flow cup are seldom ideal for making true measurements of viscosity.

It is important when using a Ford Cup and when retesting liquids that the temperature of the cup and the liquid is maintained, as ambient temperature makes a significant difference to viscosity and thus flow rate.

These new Ford viscosity cups are extremely easy to use. Simply pour your sample into the cup and measure the time it takes for the liquid to flow through the orifice until the first break in the liquid stream. Use the included table to convert the elapsed time to centistokes (cSt).

The cups are made from solid Aluminium; the orifice is made from SS All the cups are calibrated to NIST-traceable oils.
An accessory kit, a stand, and a stand with water bath ports are sold separately.

Pencil Hardness Tester

• The purpose of pencil scratch hardness tests is to determine the resistance of coating materials to scratch effects on surfaces.

• In the wolff- wilbon test, pencils of various degrees of hardness are moved over the surface under a fixed pressure and angle to the surface. The degree of hardness of the pencil which damages the surface is taken as a measurement of scratch hardness e. g. “3H” hardness.

• Instrument is supplied with set of hardness pencil, pencil sharpener, abrasive paper, operation manual, carrying case.

• This test complies with ASTM D3363, is 101
