Personal protective equipment - Eye and face protection - Occupational eye and face protectors - Part 2.Test methods1 ScopeThis part of GB/T 32166 specifies the optical and non-optical performance test methods for occupational eye and face protectors. This part applies to zero diopter protectors or components used in industry to protect the eyes or face. This part does not apply to the testing of prescription ocular and prescription assembled ocular.2 Normative referencesThe following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) are applicable to this standard. GB/T 2410 Determination of the luminous transmittance and haze of transparent plastics GB/T 23461-2009 3D dimensions of male adult headform GB/T 30042-2013 Personal protective equipment - Eye and face protection - Vocabulary (ISO 4007.2012, MOD)3 Terms and definitionsThe terms and definitions defined in GB/T 30042-2013 apply to this document.4 General4.1 Test environment Unless otherwise specified, all tests in this part shall be conducted in an indoor environment at a temperature of (23 ± 5) °C and a humidity of 30% ~ 80%. 4.2 Test headform The test headform shall meet the requirements of the three-dimensional size of the adult male headform in GB/T 23461-2009.Unless otherwise specified, the surface material of the test headform in this part is polyurethane; the base material of the headform is metal. 4.3 Reference point (for testing) During the test, the test shall be conducted at the design reference point indicated by the product. If the product does not indicate the design reference point, the test reference point shall be determined as follows.5 Test method of optical performance5.1 Spherical power, astigmatic power, prismatic deviation 5.1.1 Focimeter method 5.1.1.1 Instruments Qualified focimeter. 5.1.1.2 Test procedure After confirming the reference point according to 4.3, place the back surface of the specimen on the support of focimeter and make the reference point on the optical axis of the focimeter. Then perform the test. 5.1.2 Telescope method 5.2 Prism imbalance of assembled ocular or ocular covering both eyes 5.2.1 Instruments The principles for the testing instrument of the mutual difference of the prismatic deviation is as shown in Figure 5. 5.2.2 Test procedure After determining the reference test point according to 4.3, the test is carried out as follows. 5.3 Transmittance 5.3.1 Instruments The band of the test instrument shall meet the test requirements. The maximum allowable relative error of the transmittance (τ) test is as shown in Table 1. 5.3.2 Test procedure Under the specified wavelength range and wavelength interval, test the transmittance of the ocular and calculate the average according to the Transmittance /% Relative error /% corresponding weight function. The corresponding weight function is as shown in Appendix A of GB/T 30042-2013. 5.4 Wide angle scatter (haze) The test is carried out in accordance with the provisions of GB/T 2410. 5.5 Narrow angle scatter (light diffusion) 5.5.1 Principle If Ls is used to represent the (light) luminance of the narrow angle scatter (light diffusion) of the tested ocular, E is the (light) illuminance incident on the tested ocular, the proportional factor Ls/E is the light scattering characteristic of the tested ocular, which is called the luminance coefficient (l). 5.5.2 General Based on the principles in 5.5.1, both 5.5.3 and 5.5.4 can be used to test the reduced luminance coefficient of the ocular; meanwhile the results measured by these two methods are equivalent. If the spectral transmittance of the ocular is too low to be tested according to the method specified in 5.4, it shall be carried out in accordance with the provisions of 5.5. 5.5.3 Basic method 5.5.3.1 Instruments The principle of the narrow angle scatter testing instrument is as shown in Figure 7. 5.5.4 Simplified method 5.5.4.1 Instruments The principle of the narrow angle scatter tester is as shown in Figure 8. Use the lens L1 and L2 to expand the beam of the laser L and collimate to the reference test point of the specimen (P). Meanwhile the specimen (P) can rotate around the optical axis of the tester. 5.6 Material and surface quality test 5.6.1 Instruments The testing of the materials and surfaces quality is generally visually inspected by means of "light boxes" or illuminated grids. 5.6.2 Test procedure The human eye is about 700 mm away from the dark box’s background. Turn on the fluorescent lamp in the dark box and place the ocular to be tested 400 mm away from the dark box’s background.6 Test methods of non-optical performance6.1 Impact resistance test 6.1.1 Oculars 6.1.1.1 Instruments The test instrument is as shown in Figure 10.The basic structure can be divided into upper and lower parts. The upper half is the elevation column. The part connected to the elevation column is the positioning ruler, which can be adjusted freely and slide freely up and down. The required height can be positioned by a fixing bolt. The outer end of the positioning ruler has a steel ball feeding hole. 6.1.1.2 Test procedure Put the ocular with rubber gasket on the cylinder. Line a piece of white paper and carbon paper under the ocular. The carbon paper is on the side of the ocular. Then fix the position of the ocular by the pressure ring and bolt. Adjust the device to the required height, to make the spot emitted by the laser is projected to the center of the ocular. 6.1.2 Assembled occupational eye and face protector 6.1.2.1 Instruments The test instrument is as shown in Figure 11.The basic structure can be divided into upper and lower parts. The upper half is the same as the upper half of the instrument in 6.1.1.1; the lower half is the base equipped with the headform. The headform can rotate 90° around a horizontal axis of the base. 6.2.2 Test procedure First adjust the temperature in the oven to (55 ± 2) °C. Then put the specimen into the oven. The ocular surface shall not contact the oven wall. After keeping the temperature for (60 ± 5) min, take out the specimen and place it under normal temperature for at least 60 min. Perform visual inspection. 6.3 UV radiation stability test 6.3.1 Instruments The design of the ultraviolet irradiation box shall be reasonable, to ensure that the ocular surface is perpendicular to the ultraviolet irradiation direction. The ocular does not touch the inner wall of the box. 6.4 Corrosion resistance test 6.4.1 Reagents Reagents include. 6.6 High-speed particle impact resistance test 6.6.1 Instruments The test instrument consists of a launcher, a timer, a headform, as shown in Figure 12. The launcher is mainly composed of a steel tube of appropriate size. It shall launch a steel ball which has a diameter of 6 mm and a mass of g at the specified speed. The steel ball is located at the tail of the launch tube and powered by a spring or compressed air, to ensure the steel ball has a constant shooting speed and impact direction. The timer can be composed of a sensing element and a timer. It can record the time when the steel ball passes through the two sensing elements, in the unit of microseconds. 6.6.2 Test procedure Put the specimen to be tested on the headform at the normal use position. Adjust the tightness of the specimen’s headband according to the manufacturer's instructions. Insert the appropriate size of carbon paper and white paper between the ocular and the headform (carbon paper is on the side of the occupational eye and face protector; white paper is at the side of headform). 6.7 Heavy object impact resistance test 6.8 Anti-drop performance test (suitable for goggles protector) 6.8.1 Instruments Test instruments include. 6.9 Ocular surface wear resistance test 6.9.1 Instruments The sand falling test instrument is as shown in Figure 14. 6.9.2 Cleaning of specimen Oculars shall be cleaned using the cleaning method recommended by the product. If it does not recommend the cleaning method for the product, it may use an aqueous solution of detergent at a concentration of (1.0 ± 0.2)% to clean the ocular. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
