The work of preparing International Standards is normally carried out through ISO techn
12、ical committees. Each member body interested in a subject for which 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
13、with the International Electrotechnical Commission (IEC) on all matters 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 need
14、ed for the different types of ISO documents should be noted. This 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
15、rights. ISO shall not be held responsible for identifying any or 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).

17、rs to Trade (TBT) see the following URL: Foreword - Supplementary information The committee responsible for this document is ISO/TC 89, Wood-based panels, Subcommittee SC 2, Particle boards. This first edition cancels and replaces ISO 16893-1:2008 and ISO 16893-2:2010, which have been technically re
18、vised. This corrected version of ISO 16893:2016 incorporates the following corrections. The revision statement has been corrected in the Foreword, correctly identifying the documents which this International Standard cancels and replaces. The footer ain Table 4 has been amended and changed to NOTE 2
19、. The expression of thickness ranges have been corrected in the headers in Tables 5 to 16.iv ISO 2016 All rights reserved INTERNATIONAL ST ANDARD ISO 16893:2016(E) Wood-based panels Particleboard 1 Scope This International Standard specifies a classification matrix and the related mandatory tests an
20、d thickness ranges to be applied to wood-based particleboard for general purposes, furniture, load- bearing applications and heavy-duty load-bearing applications. It then provides the manufacturing property requirements for these types of uncoated particleboard. The values listed in this Internation
21、al Standard relate to product properties used to classify particleboards into one of four grades (P-GP, P-FN, P-LB or P-HLB, see Clause 3), for use in three service conditions (REG, MR1 and MR2). The values are not characteristic values to be used for design purposes. 2 Normative references The foll

Tables 1 and 2 apply to all product types and thickness ranges of panels. For density variation and dimensions (Table 3), specification limits are based on the mean values for individual panels (calculated in accordance with Annex A) and are maximum tolerances.
