Code of Conduct
PANEL PRODUCTS CODE OF PRACTICE All TTF Members dealing in panel products are required to adopt and comply with this Code of Practice for use as a public and promotional document forming an integral part of the TTF Code of Conduct.
Its aim is to assist Members in the promotion of their company’s efforts to correctly supply accurately marked and labelled panel products and to ensure the exposure of those known to be breaching the Code as a result of wilful product mis-labelling or mis-marking.
This Code will apply to all wood-based panel products of any thickness and is binding to all TTF Members dealing in panel products.
1.
All packing must be correctly and legibly marked with correct glue type, visual grade by face quality, nominal board thickness, manufacturer’s mark and specific country of origin. These marking requirements must also apply to all panels where practicable. These requirements shall be incorporated in all supply contracts and documentation, including sales invoices.
2.
Where products are offered as made to BS or BS EN standards, or the recognised standards of other producing nations, Members will seek to ensure that all the specification requirements of these standards are adhered to. For plywood products only, where no contractual reference is made to any of the above types of standards, nominal thickness tolerances and glue bond descriptions specified in the latest available versions of relevant standard(s) to be adhered to – refer to Panel Products Code of Practice ‘Supplementary Guidelines – Structural Panels’.
2.1 Wood-based panels for construction, as defined within the Construction Products Regulation and according to the timetable of that Regulation, will meet the specific requirements set out in the Harmonised European Standard EN 13986.
2.2
Marine Plywood supplied by Members is to meet the requirements of BS 1088 (Marine Plywood), Part 1 (Requirements) and Part 2 (Determination Of Bonding Quality Using Knife Test). These two Parts together replace the earlier version, BS 1088 & 4079 : 1966(1988).
2.3
Where plywood is marked or claimed to be ‘WBP’, then evidence must be available to show that it had undergone a 72-hour boil test and met the full requirements to achieve an EN 314, Class 3 Glue Bond.
2.4
Plywood claiming to meet the higher performance level of EN 636, Class III should, in addition to demonstrating an EN 314, Class 3 Glue Bond, also provide evidence that all veneers used in its construction were sufficiently durable for exterior use which, on the basis of the recommendation in DD CEN TS/1099, would be species listed in EN 350 as Class 3 Moderately Durable and Better, which excludes the use of sapwood. Where evidence is not available that the veneers meet this durability requirement, then written advice must be provided that a trader further down the supply-chain or end-user would have to preservative-treat or seal-treat the board in order for it to be sufficiently durable for normal exterior use.
2.5
Where products make CE or Chain of Custody claims, Members must ensure these are reproduced clearly as part of the pack marking. Where necessary this requirement is in addition to the marking requirements of these schemes.
3.
No Member shall require any manufacturer or shipper to supply any product in an unmarked or mis-marked condition.
4.
No Member will incorrectly describe any panel product offered for sale.
