6.17.5.2 Procedure
Connect the water supply. For a single\r\nflush flushing device operate the flushing device and, if appropriate, allow\r\nthe flushing cistern to refill. Carry out the long-term leak test. Three drops\r\nor more observed on the paper shall be considered a leak. Initiate automatic operation\r\nof the flushing device. Carry out the short-term leak test and inspect the\r\nflushing device after a further 2, 5, 10, 50, 100, 500, 1 000, 10 000 and every\r\nsubsequent 10 000 cycles. If a leak is detected, the leak test interval, but\r\nnot the test itself, shall restart (e.g. the short-term leak test shall be\r\nundertaken after a further 1, 2, 5, 10…cycles). Continue until 200 000 test\r\ncycles have been completed, and then subject the flushing device to the\r\nlong-term leak test. If, at any point during the test, three leaks have been\r\ndetected, the test terminates and four further flushing devices shall be\r\nsubjected to the same test, which again terminates if three leaks have been\r\ndetected for any one of the flushing devices. For\r\nflushing devices with reduced flush option, operate the flushing device for a\r\nfull-flush and, if appropriate allow the cistern to refill. Carry out the\r\nlong-term leak test. Three drops or more observed on the paper shall be\r\nconsidered a leak. The test then continues with the sequence three reduced\r\nflushes activated followed by a maximum flush. The flushing device shall be\r\nsubject to the short-term leak test after 2, 5, 10, 50, 100, 500, 1 000, 10 000\r\nand every subsequent 10 000 flushes (maximum and reduced flushes each counting\r\nas one flush). If a leak is detected, the leak test interval, but not the test\r\nitself, shall restart (e.g. the short-term leak test shall be undertaken after\r\na further 1, 2, 5, 10…cycles). Continue until 200 000 test cycles have been\r\ncompleted, and then subject the flushing device to the long-term leak test. If\r\nat any point during the test, three leaks have been detected, the test\r\nterminates and four further flushing devices shall be subjected to the same\r\ntest, which again terminates if three leaks have been detected for any one of\r\nthe flushing devices. The flushing device shall be inspected for wear at the\r\nsame frequency as the short-term leak test. If the flushing device or any of\r\nits operating linkages suffers structural failure that affects operation, the\r\ntest terminates.

6.17.11 Summary of\r\nrequirements for compatibility testing of type 2 products
This clause provides further\r\nbackground notes on the testing and compatibility of elements of the WC suite\r\nfor the purposes of this standard.
The expectation of 6.1 to 6.17 is that\r\nany element of a WC suite offered for sale independently should enable other\r\nassociated elements to meet the performance characteristics of type 2 of this\r\nspecification when combined to form a WC suite. Nonetheless, it is clearly\r\nunreasonable for the manufacturer of an independent component of a suite to\r\nensure that the product would satisfy the requirements, if installed with every\r\nother available part that could make up a WC suite. Therefore, manufacturers\r\nneed to complete those tests relevant to their product and ensure that when\r\ninstalled as part of a whole WC suite their product would be capable of\r\nfulfilling the complete set of tests. Whoever selects the components to form a\r\nWC suite should ensure that they form a compliant suite which satisfies the all\r\nthe tests in this specification. Inlet\r\nvalves shall satisfy BS 1212 as modified in 6.1.
Flushing devices shall satisfy the\r\nrequirements with regard to physical and chemical endurance. They shall also be\r\ncapable of satisfying the flush volume test at full and, if appropriate,\r\nreduced-flush volumes. They should also be capable of contributing towards the\r\nother requirements when tested in combination.
Cisterns shall consist of compliant\r\ncomponents and so satisfy warning pipe and overflow provisions and the flush\r\nvolume test They should also be capable of contributing towards the other\r\nrequirements when tested in combination.
...

The whole WC suite shall comprise of\r\nfully compliant components which, when installed together, satisfy all the\r\ntests. This shall include a cistern suitably marked for the intended full and,\r\nif appropriate, reduced flush volume of the WC pan.
It should be noted that when\r\nundertaking tests involving more than one component of a WC suite, components\r\nwhich could adversely affect the results of the whole test should not be\r\nchanged without re-starting that test.
7 Dangerous\r\nsubstances
National regulations on dangerous\r\nsubstances may require verification and declaration on release, and sometimes\r\ncontent, when construction products covered by this standard are placed on\r\nthose markets.
In the absence of European harmonized\r\ntest methods, verification and declaration on release/content should be done\r\ntaking into account provisions in the place of use.
NOTE An informative database covering\r\nEuropean and national provisions on dangerous substances is available at the\r\nConstruction web site on EUROPA accessed through:\r\nhttps://ec.europa.eu/growth/tools-databases/cp-ds_en.

Mọi chi tiết xin liên hệ: ĐT: (028) 3930 3279 DĐ: 0906 22 99 66
- factory production control by the\r\nmanufacturer (FPC), including product assessment (see 9.3).
The manufacturer shall always retain\r\nthe overall control and shall have the necessary means to take responsibility\r\nfor the conformity of the product with its declared performance(s).
9.2 Type testing
9.2.1 General
All performances related to\r\ncharacteristics included in this standard shall be determined when the\r\nmanufacturer intends to declare the respective performances unless the standard\r\ngives provisions for declaring them without performing tests (e.g. use of\r\npreviously existing data, CWFT and conventionally accepted performance).
Assessment previously performed in\r\naccordance with the provisions of this standard, may be taken into account\r\nprovided that they were made to the same or a more rigorous test method, under\r\nthe same AVCP system on the same product or products of similar design,\r\nconstruction and functionality, such that the results are applicable to the\r\nproduct in question.
For the purposes of assessment, the\r\nmanufacturer's products may be grouped into families, where it is considered\r\nthat the results for one or more characteristics from any one product within\r\nthe family are representative for that same characteristics for all products\r\nwithin that same family.
Products may be grouped in different\r\nfamilies for different characteristics.
Reference to the assessment method\r\nstandards should be made to allow the selection of a suitable representative\r\nsample.
