19、16(E) 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 committees. Each member body interested in a subject for whi
20、ch 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 International Electrotechnical Commission (IEC) on all m
21、atters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This
22、 document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or
23、all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users
24、and does not constitute an endorsement.

25、 information The committee responsible for this document is ISO/TC 89, Wood-based panels, Subcommittee SC 1, Fibre boards. This first edition cancels and replaces ISO 16895-1:2008 and ISO 16895-2:2010, of which the product classification and specification have been technically revised. ISO 2016 All
26、rights reserved v W ood-based panels Dry -pr oc ess fibr eboar d 1 Scope This International Standard specifies a classification matrix, related mandatory tests and thickness ranges for ultra-low-, low-, medium- and high-density dry process wood-based fibreboard. It then provides the manufacturing pr
27、operty requirements for these types of uncoated fibreboard. The values listed in this International Standard relate to product properties used to classify fibreboards into one of four types (UDF, LDF, MDF and HDF, see Clause 3), one of four grades (GP, FN, BL and LB), for use in one of four service
28、conditions (REG, MR1, MR2, and HMR). The values are not characteristic values to be used for design purposes. NOTE Fibreboards are broadly divided into two groups based on the manufacturing process, namely the dry process group and the wet process group (see Clause 3). Wet process fibreboards lie ou
29、tside the scope of this International Standard. 2 Normat i v e r efer en c es The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

41、 time of publication, are shown in Tables 1 to 4. Tables 1 to 4 allow for future classes to be included as they become available on international markets. Not all products in the matrices shown in Tables 1 to 4 are currently available or under development. Realistic property tables can only be devel
42、oped for existing products. The remainder are potential future products and property tables will be developed when necessary. Density ranges given in product descriptions in 5.2 to 5.5 are a guide. Manufacturers may classify a product as a particular type or grade if it meets all the property requir
43、ements of the nominated type or grade. For example, a thin fibreboard of density 830 kg/m 3could be called MDF if it meets all property requirements of the particular MDF grade nominated. 5.1.2 Uses Products specified in this International Standard have the following applications. regular REG dry co

47、 and performance requirements may be specified by national standards and regulations. ISO 2016 All rights reserved 3 ISO 16895:2016(E) 5.1.4 Structur al gr ades When a product is used in a load-bearing or structural application, additional information shall be available in the form of characteristic
48、 values derived from structural testing (see ISO 16572), experimental test results or history of use to validate its performance under the proposed conditions. It should be noted that engineering design methods do not provide for design for high humid or exterior service conditions. The inclusion of
49、 the MDF-LB grade in the “high humid” section of the classification matrix (see Table 3) is on the basis that performance is validated by experimental test results or history of use. 5.2 Ultr a-lo w -density fibr eboar d (UDF) UDF has a nominal density less than 550 kg/m 3and is classified according to Table 1.
