2、 the direction of the Sector Board for Materials and Chemicals, was published under the authority of the Standards Board and comes into effect on 15 April 1998 BSI 04-1999 ISBN 0 580 29693 8 National foreword This British Standard reproduces verbatim ISO 11379:1997 and implements it as the UK nation
3、al standard. The UK participation in its preparation was entrusted to Technical Committee PRI/3, Textile floor coverings, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposa
4、ls for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK.

A British Standard does not purport to include
6、 all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i

11、controlled Copy, (c) BSI BS ISO 11379:1997 BSI 04-1999iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committe
12、es. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Inte
13、rnational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member
14、bodies casting a vote. International Standard ISO 11379 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 12, Textile floor coverings.

16、ry-scale carpet cleaning procedure using a spray extraction technique. NOTEDepending on the characteristic under investigation, test specimens subjected to this cleaning procedure may be evaluated for many properties, e.g. ease of soil (dirt) removal, changes in appearance, effects of cleaning mater
17、ials and durability of floor covering finishes. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to r

ISO 3696:1987, Water for analytical laboratory use Specification and test methods. 3 Principle Test specimens of textile floor coverings are treated
20、in a controlled manner with a spray extraction cleaning machine. 4 Apparatus and materials 4.1 Spray extraction cleaning machine, capable of applying (3,75 0,25) litres/m2 of cleaning solution to the surface when the cleaner wand is moved accross the surface at a rate of (40 5) mm/s. NOTEThis may be
21、 achieved by using a machine with a wand width of (100 5) mm and an application rate of (0,9 0,1) litres/min or by using a machine with a wand width of (200 10) mm and an application rate of (1,8 0,2) litres/min. An antifoam agent may be used in the waste water tank of the spray extraction machine b
22、ut shall not be used in the delivery tank. 4.2 Suitable base, e.g. bench, table top or floor. 4.3 Floor covering adhesive or pressure sensitive adhesive tape. 4.4 Suction-only cleaner, canister-type, giving an airflow of (25 5) litres/s through the suction-only nozzle with a suction surface of (125
23、25) mm (15 2,5) mm. 4.5 Cleaning solution 4.5.1 Reference cleaning product, prepared to the following formula: made up to 1 litre with water conforming to grade 3 of ISO 3696. This solution is at working strength and shall be used without further dilution. 4.5.2 Cleaning product for evaluation, prep
24、ared according to the manufacturers instructions. 5 Conditioning Condition the test specimens in one of the standard atmospheres described in ISO 139 for a minimum of 24 h. 6 Preparation of test specimens Sample and select test specimens in accordance with ISO 1957. Cut a test specimen of suitable d
25、imensions from each sample, e.g. (200 300) mm, with the longer side in the manufacturing direction as shown in Figure 1. Mount the test specimen on a suitable base (4.2) using a floor covering adhesive or pressure sensitive adhesive tape (4.3). Surround the test specimen with material of comparable
26、construction and thickness of dimensions at least 100 mm greater than those of the test specimen secured to the base using the floor covering adhesive or pressure sensitive adhesive tape (4.3) (see Figure 1). Ensure this material is colourfast to prevent bleeding into the test specimen. NOTEIn some
27、cases the test specimen will be of predetermined dimensions, as it will have been used for other procedures, e.g. soiling, and the mounting arrangements will have to be adjusted accordingly. sodium dodecyl sulfate (General Purpose Reagent) 0,5 g C12/C13 alcohol ethoxylate (7 mole ethoxylation) 0,2 g

29、ouble strokes, i.e. twice backwards and twice forwards, in order to give all parts of all specimens equal treatment, as follows. The first two double strokes shall be made with the vacuum cleaner suction slot approximately 50 % on the buffer carpet and 50 % over the test area. Each subsequent series
30、 of strokes is made parallel to the first series with 50 % overlap, ending when the buffer strip at the other side is included in the overlap. 7.2 Prepare the cleaning solution (4.5). Pour the cleaning solution into the spray extraction cleaning machine (4.1). Attach the cleaning head and run the ma
31、chine prior to cleaning to obtain stable conditions, including temperature, at the point of delivery. 7.3 Spray and extract the test specimen by drawing the cleaning head at the speed of (40 5) mm/s necessary to obtain the required application per unit area (see 4.1) in the length direction both wit
32、h and against the pile lay. For the first stroke, position the cleaning head approximately 50 % over the surround carpet and 50 % over the test specimen. For each subsequent stroke, allow 50 % overlap per stroke, finally ending when the opposite side surround carpet is included in the overlap. Do no
33、t use a scrubbing action. 7.4 Turn the test specimen through 180 and repeat the process described in 7.3. 7.5 Dry the test specimen to approximately constant mass and then condition in the standard atmosphere (clause 5) for a minimum of 24 h, or proceed to the conditioning process required by any su
34、bsequent test procedure. 7.6 Suction clean the test specimen as described in 7.1 with the last stroke in the direction of the pile lay.
