Medical Protective clothing testing mainly includes the following items: barrier property testing (gas transmission quantity testing and moisture transmission testing), coefficient of friction(smoothness of material surfaces),tensile and elongation, peeling strength, heat seal strength, leak & seal, tearing and printing quality testing. Labthink Instruments Co. Ltd., meeting the demands for medical protective clothing testing, integrates medical protective clothing instruments as follows, so as to contribute to the quality testing of medical protective clothing enterprises.

1. Medical Protective Clothing Barrier Property Testing

Barrier property is defined as the barrier effects of packaging materials on gas (e.g., oxygen), liquid (e.g., water vapor) and other infiltrations. Barrier Property is the important factor affecting the product shelf-life. Relevant instruments are listed below:

A. PERME-DM2/330 Differential and Equal Pressure Methods Gas Permeability Tester: this instrument combines differential pressure method and equal pressure method in one unit. It is applicable for the gas transmission rate testing of plastic films, laminated films and sheets as well as finished packages. This instrument is fully automatic with three independent chambers and random temperature data curve fitting. It’s with temperature control; LAN data management.

B. PERME OX2/230 Oxygen Transmission Rate Testing System: is of coulometric principle and equal pressure method. This instrument is applicable for the oxygen transmission property testing of films and sheets, as well as bottles, cans and boxes. This instrument is of master base and satellite module mode: one master base can support 9 satellite modules with the realization of 30 samples tested simultaneously.

C. VAC-V Series Differential Pressure Gas Permeability Tester: is applicable for the oxygen, nitrogen and carbon dioxide permeability testing of plastic films and sheets as well as laminated films. This series of instruments, including VAC-V1, VAC-V2 and VAC-V3, etc., complies with differential pressure method.

D. PERME W3/330 Water Vapor Transmission Rate Testing System: is used for the water vapor transmission rate testing of films and sheets as well as bottles, bags, cans and boxes. This instrument is of Master–satellite mode, one master base can connect 9 satellite modules with the realization of 30 samples tested simultaneously.

E. TSY-T Series Water Vapor Permeability Tester: is applicable in the water vapor transmission testing of packaging materials such as films and laminated films as well as high polymer products. This series of products are fully automatic, computer control and of weighing method. The series includes TSY-T1H, TSY-T1L and TSY-T3, etc.

2. Medical Protective Clothing Strength Testing

Medical protective clothing strength testing includes index testing like material tensile strength testing, peeling strength testing of laminated films, hot seal strength testing, tearing strength and pouch resistance testing. Tensile strength is the maximum strength value just before the material is snapped. Through testing, the package damage and rapture caused by external forces and insufficient packaging material mechanical strength can be resolved effectively. Peeling strength testing, also called complex strength testing, tests the bond strength between the layers of laminated films. If the bond strength is too low, leakage is easily caused by separation among the layers. Hot seal strength testing is to test the strength of the seals. During storage and transportation of products, low hot seal strength will cause problems such as rending and leakage. Pouch resistance is the index evaluating the anti-puncture strength of the package against rigid material.

Relevant testing instruments are as follows:

A. XLW Series Auto Tensile Testers: are for the peeling, tensile, heal seal and tearing tests of films, laminated films, adhesives and tapes. This series of products includes XLW,XLW(B),XLW(M),XLW(PC)and XLW(G).

B. BLD-200S Auto Stripping Tester: is for the peeling, tensile and heat seal testing for films, laminated films, adhesive and tapes. The standard specifications are 200N (100N, 50N and 30N); mini-printer and computer connective.

C. HST-H3 Heat Seal Tester: is for the specimen preparation for the heat seal strength testing of films. Testing pressure, temperature and time are adjustable. This instrument adopts microcontroller for intellectual operation and PID high precision components for temperature so as to ascertain accurate temperature.

D. RTD-R2 Gradation Heat-Sealing Instrument: can prepare five groups of plastic films or flexible packaging laminated films simultaneously under five independent temperatures; and seal five groups of specimen simultaneously and efficiently.

3.Medical Protective Clothing Sealing Property Testing

The medical protective clothing sealing property testing can guarantee the completeness of the whole package and avoid leakage and deterioration caused by the inferior sealing property.

A.MFY-01 Leak Tester: is applicable for the package seal reliability testing by vacuumizing test chamber. Micro-computer control, panel operation, digital parameter pre-set and full-automatic testing.

B. LSSD-01 Leak and Seal Strength Detector: is for the heat seal and sealing completeness testing of bags, plastic bags and packages. The instrument is with intellectual testing process, LCD display, statistics communication and positive principle.

4.Medical protective clothing impact resistance testing can guarantee the effective protection of user. Impact resistance property testing can be classified as dart impact and pendulum impact.

A. Labthink BMC-B1 Falling Dart Impact Tester: is applicable in quality and energy testing of plastic films and sheets under the attack of free-falling dart at given heights, according to free-falling dart theory.

B. Labthink FIT-01 Film Impact Tester: is applicable to evaluate the force damaging the plastic film, laminated film, sheet and foil sample with its hemisphere head falling at certain speeds, so as to bring forward shock resistance evaluation of the material by measuring the consumed energy of the head.

5.Medical Protective Clothing Tearing Property testing

Tearing of medical protective clothing may occur because of external forces in storage, transportation and usage. Sufficient tearing resistant forces can reduce tearing and avoid dangers.

SLY-S1 Tearing Tester complies with Elmendorf method, and is applicable in tearing resistance test of films, laminated films, foils, paper and paper boards.

6.Medical Protective Clothing Coefficient of Friction Testing (Surface Smoothness)

Proper smoothness of the two sides of the clothing material can guarantee the good performances as well as smooth transportation and packaging in the assembly line.

A. MXD Series of Coefficient of Friction Tester is applicable in static and kinetic coefficient of friction test to plastic film, foils, sheets and paper. Through testing the smoothness of the materials, comfortableness and safety of medical protective clothing can be guaranteed to meet the demands. This series of products includes MXD-01, MXD-01A and MXD-02.

B. FTP-F1 Friction/Peel Tester: is computer control, and can test the material coefficient of friction between room temperature and 99.9 Centigrade as well as peeling strength of laminated films and adhesive products.

7.Medical Protective Clothing Testing for Thickness

Thickness is the basic index to test films. Uneven thickness would influence the tensile strength and barrier property as well as the following processing.

A. CHY-C2 Thickness Tester: is for the measurement of films, sheets and paper with mechanical contacting method, with no limitation for measured materials. Import high quality sensor with the resolution up to 0.1 μm. The contact area and pressure between measure head and film/paper complies with relevant standards strictly, including multi-standards such as ISO and ASTM.

B. CHY-CA Thickness Tester: is of high precision up to 0.1μm, multi-point automatic continuous testing, LCD display, micro-printer and other distinguished functions of statistics and communication.
