3、Committee. A wide range of cleaning and polishing cloths is in use for different applications. BS 7033 specifies requirements for a limited range of cloths suitable for cleating and polishing applications, and is being published in five Parts as follows: Specification for optical polishing cloths fo
4、r use on transparent plastics panels; Specification for industrial wipers from reclaimed materials, and waste yarn for cleaning and lubricating purposes; Part 3 Specification for floorcloths and dishcloths; Part 4“ Specification for window cleaning cloths; Part 5* Specification for general polishing
5、 cloths. In this Part, requirements are specified for floorcloths and dishcloths. Many properties cannot be specified objectively and cannot therefore be included in this standard. Examples of such properties include colour, handle, appearance and details of additional design features. Public sector
6、 purchasing authorities may be able to supply standard patterns which cover these properties and serve to resolve any ambiguities of description. The standard ohiy covers the basic description of the products and their construction and performance require- ments. Purchasing authorities therefore may
7、 need to include additional information.

NOTE. The titles of the publications referred to in this sta
11、ndard are listed on the inside back cover. 2 Definitions For the purposes of this Part of BS 7033 the following definitions apply. 2.1 batch. A definite quantity of some commodity manufactured or produced under conditions which are presumed uniform. 2.2 dishcloth. A short-life or durable cloth suita
12、ble for washing-up applications and general wet wiping of hard surfaces. 2.3 floorcloth. A durable cloth suitable for wet cleaning of hard floors, or other similar surfaces, by hand or under a mopping tool. 3 Requirements 3.1 General Floorcloths and dishcloths shall be square or rectangular and shal
13、l comply with table 1. NOTE. The raw edges of the cloths should be secured sufficiently to maintain the integrity of the cloths during their projected working life. 3.2 Durability After washing 30 times in accordance with A.9, not more than one specimen shall exhibit surface damage such as holes or
14、tears. 4 Sampling, conditioning and compliance 4.1 Sampling Sampling shall be carried out in such a manner that samples taken are representative of the manufacturing, processing, dyeing or finishing batch from which they are drawn. NOTE. A sufficient number of representative samples shall be taken t
15、o carry out all the tests specified in table 1. 4.2 Conditioning of specimens Specimens shall be conditioned for a minimum of 24 h, and tested in the standard temperate atmosphere for testing of textiles as defined in BS 1051, .e. a relative humidity of 65 f 2 % and a temperature of 20 f 2 C. In the
16、 event of a dispute, samples shall be pre-conditioned for 4 h in a relative humidity not exceeding 10 % at a temperature not greater than 50 OC before being exposed to the standard temperate atmosphere for testing of textiles. 4.3 Compliance In the event of a dispute, if any of the specimens tested
17、do not comply with any requirement of this standard, the tests that the specimens have failed, shall be repeated twice. For this purpose, two further samples shall be taken from the same batch as the original sample, and the same number of specimens as for the original test shall be taken from each
18、sample so that duplicate tests may be conducted. If all the re-test results are in accordance with the require- ments given, the bulk of the cloths that the samples represent shall be deemed to comply with the requirements of this standard. If any of the results of the re-test are not in accordance
19、with the requirements, the bulk of the cloths that the samples represent shall be deemed not to comply with the requirements of this standard. 5 Marking Each package shall bear the following information: (a) the name, trademark, or other means of identification, of the manufacturer; (b) the number a
20、nd date of this British Standard, .e. BS 7033 : Part 3 : 1989* and the appropriate cloth . reference; (c) the month and year of manufacture; (d) the number of cloths per package. NOTE. In addition, each package should bear such other markings as the contract or order may direct. *Marking BS 7033 : P

A.2 Area and shortest edge A.2.1 Test at least five cloths, selected at random from the bulk, in accordance with 4.1. A.2.2 Determine the width of each spec
25、imen in accor- dance with BS 1930 except that it shall be measured to the nearest 5 mm. A.2.3 Determine the length of each specimen in accordance with BS 1931 except that it shall be measured to the nearest 5 mm. A.2.4 The area a (in cm2 1 of each specimen is calculated from the equation: where a=wL
26、 w is the width of the specimen (in cm); L is the length of the specimen (in cm). Calculate the mean area of the five specimens. A.2.5 Record the length of the shortest edge (width or length) of each of the five specimens. Calculate the mean length of the five shortest edges. A.3 Mass per unit area
27、A.3.1 Woven and knitted cloths Carry out the test in accordance with method 5 of BS 2471. A.3.2 Nonwoven cloths Carry out the test in accordance with method 3 of BS 247 except that the width of the cloth shall be determined in accordance with A.2. A.4 Wet burst strength Carry out the test in accorda
28、nce with BS 4768 except for the following modifications: Number of specimens. At least 1 O cloths shall be sampled in accordance with 4.1. Procedure. Immerse the test specimens for a minimum period of 5 min in water containing 1 g/L of sodium dioctyl sulphosuccinate. Allow to drain for 5 f 1 min and
29、 immediately measure the bursting strength in accord- ance with BS 4768 using a 30 mm diameter diaphragm. A.5 Wet burst strength after washing Determine the wet burst strength in accordance with A.4 after carrying out 30 washing and drying cycles in accord- ance with A.9. Express the wet burst stren
30、gth after washing as a percentage of the wet burst strength before washing.
