INTERNATIONAL ORGANIZATION FOR STANDARDIZATION l MEXAYHAPOflHAII OPI-AHW3ALIWII I-IO CTAHAAPTW3ALW-4 *ORGANISATION INTERNATIONALE DE NORMALISATION Solid wood paving blocks - General characteristics Blocs de pavage en bois massif - Caractkristiques g - 20 % for softwood. For h
2、igher moisture contents, these dimensions will be appropri- ately increased. 4.3 Moisture content The maximum moisture content of paving blocks shall be 16 % for paving blocks used in covered (indoor) spaces and 20 % for paving blocks used in open (outdoor) spaces, before impregnation. 5 PROTECTION
3、OF WOOD PAVING BLOCKS 5.1 Solid wood paving blocks shall be protected by impregnation with antiseptic f ire-proof and/or water-proof substances that tan improve the physical properties of the blocks. The types of substances shall be established by agreement between the interested Parties. 5.2 The tr
4、eatment is applied according to the use of paving blocks (for pavements to be laid in covered or open spaces) by one of the following treatment processes : by vacuum-pressure, by (hot or cold) steeping or in hot-and- cold open tanks or by other similar and efficient methods. 5.3 The impregnation wit
5、h appropriate antiseptic substances prescribed by the producing plant shall be carried out by specialized concerns which will guarantee the quality of impregnation by providing a certificate of quality. 6 SAMPLING 6.1 The inspection of the characteristics of solid wood paving blocks shall be carried
6、 out, in compliance with the requirements set down below, on paving blocks comprising a representative Sample which has been taken from the batch. 6.2 Unless otherwise agreed upon between the interested Parties, a batch consists of a number of paving blocks of the same wood species, type or variant
7、and dimensions (length or diameter, height), presented in a Single delivery for inspection. A Sample shall be taken from each batch.

12、ving blocks of dimensions representative of the average of the batch, taken at random from the batch. The size of Sample depends on the size of batch, in accordance with table 4. 6.4 When the number of rejected paving blocks does not exceed the values specified in table 4, the batch is accepted. Oth
13、erwise, the said batch shall be regrouped and presented for a new inspection. 7 INSPECTION METHOD 7.1 Solid wood paving blocks making up a Sample shall be i nspected individually in respect of wood species, appearance, nominal dimensions and wood defects. The moisture content shall be determined as
14、specified in 7.1.4. The permissible defects shall be inspected according to the International Standards referring to the classif ication of paving blocks made from different wood species. 7.1.1 The wood species and the appearance shall be visually examined. 7.1.2 The dimensions shall be measured wit
15、h measuring instruments ensuring the specified degree of accuracy, as follows : - the width, the diameter and the length of a paving block are checked at both ends and in the middle of the paving block; - the height is checked parallel to the longitudinal axis of the paving block. Esch measurement s
16、hall be within the toleranced dimensions prescribed in 4.2. 7.1.3 The dimensions of measurable defects shall be measured with measuring instruments ensuring the specified degree of accuracy. Non-measurable defects shall be visually examined. Size of batch (number of paving blocks) 7.1.4 The moisture
17、 content shall be determined on a test specimen tut from the middle of a paving block taken at random from each Sample. Unless otherwise agreed upon by the interested Parties, the moisture content shall be determined by an electrometric method. The moisture content of paving blocks shall be determin
18、ed before impreg- nation. NOTE - In the case of disagreement, the moisture content shall be determined by the gravimetric method specified in ISO 3130. 8 DESIGNATION Paving blocks shall be designated by stating successively : - the name of the product; - the Symbol of the wood species according to I
19、SO 2036; - the type or the variant; - the nominal dimensions (width - diameter - length - height), expressed in millimetres; - the number of the International Standard referring to the respective wood species.
