Grey Scale For Colour Fastness

The Grey Scale for Colour Fastness manufactured by Glass Agencies under the EROSE brand is a textile testing accessory used for visual evaluation of colour change and staining in fabrics. This scale is widely used in textile laboratories, garment testing units, quality inspection departments, educational institutes, and research centers where colour performance of fabrics needs to be assessed after washing, rubbing, perspiration, or light exposure tests. The grey scale consists of a series of paired grey colour chips arranged in progressive contrast levels. These pairs allow users to compare the degree of colour change or staining on test specimens against standard reference shades. The gradual variation between grey tones supports consistent visual judgment and helps maintain uniform assessment standards across different testing environments. The scale supports assessment according to commonly followed textile testing methods. Manufactured using carefully matched grey tones, the EROSE Grey Scale for Colour Fastness supports accurate visual comparison under standard lighting conditions. The surface finish of the scale allows clear visibility of each shade without glare, supporting comfortable viewing during evaluation. The scale is suitable for checking both colour alteration of the tested fabric and transfer of colour onto adjacent materials. Glass Agencies ensures that each grey scale is produced with consistent shade values and proper alignment of colour steps. The scale is typically supplied in a protective case to prevent dust exposure and surface damage during storage. Its compact form allows easy handling during testing and convenient placement on laboratory worktables. The grey scale is commonly used during washing fastness tests, rubbing fastness tests, perspiration fastness checks, and light exposure studies. During evaluation, the tested fabric is visually compared with the reference scale to determine the grade of colour change or staining. This process supports standardized reporting of results, making it useful for communication between manufacturers, buyers, and inspection agencies. Maintenance of the Grey Scale for Colour Fastness is simple and involves keeping the surface clean and protected from direct sunlight when not in use. Proper storage helps maintain shade consistency over extended periods. The scale does not require calibration or electronic components, making it suitable for repeated use in routine textile testing work. The EROSE Grey Scale for Colour Fastness reflects Glass Agencies’ commitment to supplying dependable textile testing accessories that support consistent evaluation practices. Each unit is checked before supply to ensure correct shade progression and proper presentation. This grey scale remains a trusted assessment tool for laboratories and institutions involved in fabric quality evaluation and textile performance testing.
