AS ISO 10545.1 pdf download.Ceramic tiles Method 1: Sampling and basis for acceptance
1  Scope
This part of ISO 10545 specifies rules for batching, sampling, inspection, and acceptance/rejection of ceramic tiles.
2  Terms and definitions
For the purposes of this document, the following terms and definitions apply. 2.1 order quantity of tiles ordered at one time Note 1 to entry: An order may consist of one or more consignments. 2.2 consignment quantity of tiles delivered during a period of 2 d 2.3 homogeneous consignment/subconsignment consignment or subconsignment that consists of tiles from one manufacturer, produced under conditions and with properties that are presumed uniform 2.4 inspection lot quantity of tiles submitted for inspection manufactured by one manufacturer under conditions and with properties that are presumed uniform 2.5 sample specified number of tiles taken from an inspection lot 2.6 sample size number of tiles to be tested for each property 2.7 requirement required characteristic as specified for the property in the relevant product standard 2.8 non-conforming unit tile that does not meet the requirement for the property concerned
3  Principle
This part of ISO 10545 provides for a sampling inspection system with a double sampling plan, partly for the method of inspection by attributes (individual values) and partly for a method of inspection by average values (variables). The number of tiles to be tested varies for each property (see Table 1).
4  Constitution of inspection lots
An inspection lot can consist of one or more homogeneous consignments or subconsignments. Any consignment which is not homogeneous shall be divided into subconsignments which are assumed to be homogeneous and which might then constitute inspection lots. If non-homogeneity is not relevant to the properties to be tested, by agreement between the supplier and consumer, the consignment can be treated as homogeneous. NOTE  For example, a consignment of tiles, of the same type with different glazes, can be homogeneous with regard to dimensions and water absorption and non-homogeneous with regard to surface quality. In the same way, accessories which differ only in shape from the remaining tiles in the sample can be considered homogeneous with respect to the other properties.
5  Extent of the inspection
The choice of properties to be considered for inspection shall be subject to agreement between the supplier and consumer and might depend on the size of the inspection lot. NOTE  In principle, a complete range of tests has to only be executed for inspection lots of more than 5 000 m 2 of tiles. Testing is usually not considered to be necessary for inspection lots of less than 1 000 m 2 of tiles. The number of inspection lots to be drawn for testing shall be subject to agreement between the parties concerned.
6  Sampling
6.1 The sampling location shall be subject to agreement between the supplier and consumer. 6.2 One or more representatives of each party concerned can be present at the time the sample is taken. Samples shall be taken at random from the inspection lot. Two samples shall be taken. It might not be necessary to test the second sample. Each sample shall be packed separately and shall be sealed and marked as agreed by the parties concerned 6.3 For each property, the number of tiles to be tested is indicated as “sample size” in column 2 of Table 1.
7  Inspection
7.1 The tiles in the sample shall be tested according to the test methods specified in the relevant product standards. 7.2 The test results shall be evaluated according to Clause 8.
8  Determination of acceptability of inspection lots
8.1  Inspection by attributes 8.1.1 When the number of non-conforming units found in the initial sample is less than or equal to the acceptance number Ac 1 , indicated in column 3 of Table 1, the inspection lot from which the sample was drawn shall be considered acceptable.
