ADDIGUARD - Water Repellency (water/alcohol) Grades A or B: Test liquid used complies with the norm (APPROVED). Grades C or D: Test liquid used does not comply with the norm (NOT APPROVED) ADDIGUARD - Grease Repellency (hydrocarbon solvents) Grades A or B: Test liquid used complies with the norm (APPROVED). Grades C or D: Test liquid used does not comply with the norm (NOT APPROVED) ADDIGUARD - Spray Test -AATCC Test Method 22 SPRAY TEST RATING CHART 100 - No sticking or wetting of upper surface. 90 - Slight random sticking or wetting of upper surface. 80 - Wetting of upper surface at spray points. 70 - Partial wetting of whole of upper surface. 50 - Complete wetting of whole of upper surface. 0 - Complete wetting of whole upperr and lower surfaces. ADDIGUARD - Bundesmann - EN 29865 Bundesmann - EN 29865 - Rain on samples through 300 nozzles - Time: 10 minutes - Visual assessment: values from 1 - 5 - Weighting the samples after removing them from test - Determination of the flux through the samples ADDIGUARD - Abrasion Determination of resistance to abrasion and use. Crockmeter with water sandpaper number. 600 - Performs 5 cycles. ADDIGUARD - Dry Soil Test Dry Soil Test Measures the tendency of the substract to resist to dust during use. The fabric is dirtied with standardized dry soil, after which is cleaned with compressed air. ADDIGUARD - Soil Release Testing Method Soil Release Testing Method 1 - Put a drip of dirty motor oil in a testing piece of cloth. Further, load a weight of 0,5kg for a minute. 2 - Then, take away the weight and leave the testing piece for 24 hours. 3 - Then, wash the piece for 15 minutes and dry. Measure it by reflectometer. 4 - Degree of staining to be calculated by the following formula: ADDIGUARD - Durability Durability a) Home washing (AATCC # 135) b) Dry Cleaning (normally with com percloroethylene) Note: After washing the product must be ironed so that the product performs again 100% of its functions. ADDIGUARD - Water Column (Hydrostatic Pressure) Measures the "impermeability" of the material in millimeters (mm). It is the theoretical height of water that could be on top of the material before it goes through it. The value of a 1,000 mm water column is similar to a pressure of 1 bar.
