AATCC 171 pdf free download.Carpets: Cleaning of; Hot Water Extraction Method.
1. Purpose and Scope
1.1 This test method provides a laboratory procedure to clean textile floor coverings by a technique simulating cleaning of installed floor coverings by hot water extraction, sometimes erroneously called “steam cleaning.”
1.2 This test method may be used to clean a carpet in a manner that duplicates the most popular (70%) means of actual on-floor cleaning of carpets.
1.3 This test method prepares specimens that can be tested for many properties: e.g.. colorfastness, dimensional stability, permanency of finishes, ease of cleaning, etc.
2. Principle
2.1 The test is performed by securing a specimen of carpet, face up, on a floor or a mounting board. An extraction cleaning head is passed over each section of the specimen. The pile is erected with a brush or pile rake and the specimen is dried at room temperature.
3. Terminology
3.1 carpet. n.—all textile floor coverings not designated as rugs.
3.2 carpet pile brush, n.—a hand operated brush having long, semi-rigid bristies intended specifically for erecting the pile of small areas of carpet. (see also pile lifler).
3.3 cleaning head, n.- a vacuum head modified with spray nozzles for cleaning solution application. Some types include a powered brush unit to facilitate wetting and soil release.
3.4 hot water extraction, n.a method of cleaning carpet by injecting a heated cleaning solution into the pile and quickly removing the solution and soil by vacuum. (see also stean cleaning).
NOTE: Hot water extraction is often erroneously called ‘steam cleaning.” Hot water is used at a temperature of 60 ± 3°C (140 ± 5°F). These temperatures are far below the temperature of steam of 100°C
(212°F).
3.5 pilate, n.—see pile lifting.
3.6 pile lifter, n.—a vacuum cleaning device with motorized rotating brushes designed to erect and agitate carpet pile to facilitate soil removal. (sec also carpet pile brush).
3.7 pile lifting. n.—the act of erecting the pile tufts of a carpet with a carpet pile brush, pile lifter, or pii’ rake to allow itii— bedded soil to be more easily removed and erecting the pile after cleaning to restore a uniform overall appearance. (also called pilate).
3.8 pile rake. n.—a hand tool with smooth circular plastic tines used for pile lifting.
3.9 rug, n.— a textile floor covering of limited area which is complete in itself and is intended for use as a partial covering of a floor or another floor covering.
3.10 steam cleaning. n.—see the correct term, hot water extracilon.
3.11 textile floor covering, n.– an article having a usc-surface composed of textile material and generally used for covering floors.
3.12 LIse-surface, n.—oJ textile floor covering, the part of a textile floor covering directly exposed to foot traffic.
3.13 wand, n.—a tool used to deliver cleaning solution to carpets and apply vacuum to remove the solution.
NOTE: A wand usually consists of an extension handle and a cleaning head. Various types are light weight wand, drag wood (heavy duty) and power wand which has a motorized rotating or vibrating part to aid soil release.
4. Safety Precautions
NOTE: These safety precautions are for information purposes only. The precautions are ancillary to the testing procedures and are not intended to be all inclusive. It is the user’s responsibility to use safe, and proper techniques in handling materials in this test method. Manufacturers MUST be consulted for specific and other manufacturer’s recommenda(ions. All OSHA standards and rules must also be consulted and followed.
4.1 Good laboratory practices should be followed. Wear safety glasses in all laboratory areas.AATCC 171 pdf download.
