Foreword
Article 4 of this Standard is compulsory; the others are voluntary.
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB 18580-2001, Indoor Decorating and Refurbishing Materials
– Limit of Formaldehyde Emission of Wood-Based Panels and Finishing Products.
Compared with GB 18580-2001, the major changes of this Standard are as follows.
-- it cancels classification;
-- it modifies the test method of 1 m3 climate chamber into reference;
-- it cancels the 40 L desiccator method and limit values. It cancels the limit values
for the (9 ~ 11) L desiccator method and perforator extraction method;
-- the (9 ~ 11) L desiccator method and perforator extraction method only apply to
production quality control;
-- it adds the gasometric analysis method for production quality control;
-- it modifies the articles of inspection rules;
-- it cancels the articles of product marking.
The formaldehyde emission 1 m3 climate chamber method of this Standard is
consistent with ISO 12460-1.2007 Wood-based Panels – Determination of
Formaldehyde Release – Part 1. Formaldehyde Emission by the 1-cubic-meter
Chamber Method. The limit values are basically consistent with the corresponding
parts of ISO 16893.2016 Wood-based Panels – Particleboard and ISO 16895.2016
Wood-based panels -- Dry-process Fibreboard.
This Standard was proposed by the State Forestry Administration.
This Standard shall be under the jurisdiction of the National Standardization Technical
Committee on Artificial Boards (SAC/TC 198).

Indoor Decorating and Refurbishing Materials –
Limit of Formaldehyde Emission of Wood-Based
Panels and Finishing Products
1 Scope
This standard specifies the index values, test methods and inspection rules of formaldehyde
emission of wood-based panels and finishing products (including floorboard and wallboard,
etc.) used for indoor decorating and refurbishing.
This standard is applicable to various wood-based panels and finishing products for indoor
decorating and refurbishing that release formaldehyde.

The following standards contain provisions which, through reference in this standard,
constitute provisions of this standard. For dated reference, the subsequent amendments
(excluding corrigendum) or revisions of these publications do not apply. However, the
parties who enter into agreement according to this standard are encouraged to study whether

GB/T 17657-1999 "Test Methods of Evaluating the Properties of Wood-based
Panels and Surface Decorated Wood-based Panels"
3 Terms and Definitions
The following terms and definitions are applicable to this standard.
3.1
Formaldehyde emission — the perforator test value
The formaldehyde amount extracted from 100g of absolute dry wood-based panels that is
determined by perforator method.
3.2
Formaldehyde emission — the desiccator test value
The formaldehyde amount released from the specimen into the absorption solution (distilled
water) that is determined by desiccator method.
3.3
Formaldehyde emission — the chamber test value
The formaldehyde amount released from the specimen into the air under the stable state that
is determined by the chamber specified in this standard.
3.4
Volume of the chamber
For the air sampling and analysis, firstly connect the air sampling system to the chamber’s
air outlet. Respectively fill 25ml of distilled water into 2 absorption bottles. Start the air
pump. Control the pumping speed at about 2L/min. At least pump out 100L of air every time.
Respectively take 10mL of absorption solution from each bottle and transfer it into 50mL
volumetric flasks. Add 10mL of diacetone solution and 10mL ammonium acetate solution
into each flask. Place the flask in 40°C water bath. Heat for 15min. Then keep the solution at
dark place to let it cool down to the room temperature (about 1h). Measure the absorbance
with the spectrophotometer set at 412nm. Meanwhile, carry out parallel determination of
blank value with 10mL of distilled water, 10mL of diacetone solution and 10mL of
ammonium acetate solution. The difference BETWEEN the absorbance test value of
absorption solution AND the blank test value is multiplied by the slope of the calibration
curve; then it is further multiplied by the volume of absorption solution; that is the
formaldehyde amount in each absorption bottle. The formaldehyde amount in 2 absorption
bottles is the total formaldehyde amount. The total formaldehyde amount is divided by the
volume of air pumped-out, that is the formaldehyde concentration value in per cubic meter
of air, expressed in milligrams per cubic meter (mg/m3). As the air volume displayed on air
meter is the air volume that is pumped-out at the test-chamber’s temperature, and that is not
the air volume at 23°C in chamber, therefore, the air sample volume shall be calibrated to
the volume at the standard temperature 23°C in accordance with the gas equation.
The calibration curve for spectrophotometer and the determination of the slope of calibration
curve shall be carried out in accordance with 4.11.5.5.2 of GB/T 17657-1999.
7 Inspection Rules
7.1 Inspection classification
Inspection items in this standard are of type inspection.
7.2 Sampling
3 samples specified in the test method shall be randomly sampled from the wood-based
panels and finishing products, of the same place, same type and same specifications. And
they shall be immediately sealed with such packing materials that it will not release or
adsorb formaldehyde before the test. When sampling at manufacturer site, the samples must
be taken from the products with quality certificate in the finished products storage. When
sampling at distributor site, the samples must be taken from the products with quality
certificate at the distribution site or in the distributors' finished products storage. When
sampling at the construction or application site, samples must be randomly taken from the
same kind of products at the same place.
7.3 Judgement rules and re-inspection rules
Any one sample shall be taken from the three randomly extracted samples to test the
formaldehyde emission in accordance with those specified in this standard. If the test result
meets the requirements stated in this standard, this product shall be judged as "qualified". If
the test result fails to meet the requirements stated in this standard, then the additional 2
samples shall be tested. If the 2 samples meet the requirements, the product shall be judged
as "qualified"; if only 1 of 2 meets the requirements or neither one meets the requirements,
then the product shall be judged as "unqualified".
7.4 Inspection report
7.4.1 The inspection report shall include product name, specification, type, grade,
manufacturing date, and the inspection based standard.
7.4.2 The inspection result, conclusion, and sample’s moisture content.
7.4.3 Abnormal conditions appeared during the inspection and other problems that need to
be explained.
8 Product Marking
The products shall be marked with product name, product standard number, trademark,
manufacturer name, detailed address, origin of the product, product specification, model,
grade, and marking of formaldehyde emission limit.
