Audited Supplier Formaldehyde Testing Chamber Climate Test Chamber
Machine Introduction
The formaldehyde testing chamber is used to test formaldehyde emission of various wood-based panel, composite wood flooring, carpet, carpet padding, and other interior decoration materials, also other building materials under constant temperature humidity.
Implementation Standard:
ASTMD6007-02: standard test method for determination of formaldehyde concentration in wood products by small scale environment box
ENV717-1: formaldehyde emission measurement environment box method of artificial board
EN13419-1: the method for determining the release of VOCs for building products in the first part of the test environment box
Reference standard:
ASTMD5116-97: standard guide for the determination of organic release of indoor materials and products in small scale environment boxes
ASTMD6330-98: "standard operation for the determination of VOCs (deformaldehyde-formaldehyde) release in wooden panel under test conditions"
ASTMD6670-01: standard operation for measuring the release of indoor materials and VOCs in a full-scale environment box
ASTME1333-96: standard test method for determination of formaldehyde concentration and release rate in wood products by large environment box
working principle
Put sample of 1 square meter area into the temperature chamber which controlled control in a certain value of temperature, relative humidity, air velocity. The formaldehyde released from samples, mixed with the air in the cabinet, regular extraction in the air, and the air will be drawn through the absorption bottle is filled with distilled water, all the formaldehyde in air dissolve in the water; Measure the amount of formaldehyde in the absorption solution and extraction of air volume, and show it by micrograms per cubic meter (mg/m after), calculate the amount of formaldehyde in per cubic meter of air. Sampling is cyclical, until the test the formaldehyde concentration in the oven to reach equilibrium.
