Mold test

Product Details

Mold testing is the process of testing a product or material under conditions that are conducive to mold growth, in order to assess its resistance to mold. Evaluate the different degrees of mold growth and the surface changes and performance effects caused by mold on products, providing necessary basis for material selection, manufacturing, packaging, etc.

Qualification and Capability:

Approved by China Metrology Certification (CMA) and China National Accreditation Service for Conformity Assessment (CNAS).

Scope of application:

Mold testing can be conducted for military equipment, electronic products, instruments, components, and materials.

Testing standards:

GB/T 2423.16-2008 "Environmental testing for electrical and electronic products - Part 2: Test methods - Test J and guidelines: Mold growth"

RTCA/DO-160E/F/G Airborne Equipment Environmental Conditions and Test Procedures

Test cycle:

28 days for sample appearance inspection and 84 days for performance inspection.

Scope of application (selection of bacterial strains):

Table 1 lists two commonly used bacterial strains. During the experiment, one group was selected, and if necessary, additional strains can be added on top of the selected group.

Table 1: Groups and types of bacterial strains that can be selected for the experiment

Number of bacterial strains	Mold name	Strain number	Affected materials
1	aspergillus niger Aspergillus niger	AS3.3928	Fabric, vinyl resin, conformal coating, insulation materials, etc
	Aspergillus terreus Aspergillus terreus	AS3.3925	Canvas, cardboard, paper
	Wan's Penicillium paecilomyces varioti	AS3.4253	Plastic, leather
	Penicillium funiculosum Penicillium funiculosum	AS3.3875	Fabric, plastic, cotton fabric
	Penicillium ochrochloron Penicillium ochrochloron	AS3.4302	Plastic, fabric
	scopulariopsis brevicaulis Scopulariopsis brevicaulis	AS3.3985	rubber
	Green wood mold Trichoderma viride	AS3.2942	Plastic, fabric
2	aflatoxin Aspergillus flavus	AS3.3950	Leather and fabric
	A. versicolor Aspergillus versicolor	AS3.3885	leather
	Penicillium funiculosum Penicillium funiculosum	AS3.3875	Fabric, plastic, cotton fabric
	Ball mold Chaetomium globosum	AS3.4254	cellulose
	aspergillus niger Aspergillus niger	AS3.3928	Fabric, vinyl resin, conformal coating, insulation materials, etc
Note: The strain number is the strain number in the "Catalogue of Strains" compiled by the China General Microbial Strain Collection and Management Center in 1997.
