Test and detection

Are you worried about designing test methods? Confirm the draft test report, and you don't know how to solve the problems during the test? Don't worry, our test supervision service helps you solve all the problems during the test, so that you can easily complete the test work.

The testing items we provide supervision services include registration testing of new chemical substances, classification and identification testing of hazardous chemicals, testing of new raw materials for cosmetics, etc.

New Chemical Registration Test

According to the requirements of the Environmental Management Measures for New Chemical Substances, new chemical substances need to be tested before registration. The test method is mainly based on the Chemical Registration Center of the Ministry of Ecology and Environment (formerly the Chemical Registration Center of the Ministry of Environmental Protection) issued in 2015. "Chemical Test Methods" (Second Edition). Chemical Testing Methods is divided into four volumes: physical and chemical properties and physical hazards volume, degradation and accumulation volume, biological system effects volume, health effects volume.

Classification and identification test of hazardous chemicals

According to the provisions of the Measures for the Administration of Physical Hazard Identification and Classification of Chemicals (Order No. 60 of the State Administration of Work Safety), for chemicals whose physical hazard characteristics have not yet been determined, the registered enterprise shall, in accordance with the relevant national regulations on chemical hazard identification, entrust an institution with national qualifications to conduct physical hazard identification; if it is a hazardous chemical, registration shall be carried out in accordance with the provisions of the Measures for the Administration of Registration of Hazardous Chemicals (Order No. 53 of the State Administration of Work Safety).

Management Scope of Physical Hazard Identification and Classification of Chemicals

The following chemicals shall be subject to physical hazard identification and classification:

1. Chemicals containing one or more components listed in the Catalogue of Hazardous Chemicals (2015 Edition), but the overall physical hazard has not been determined;

(2) Chemicals that are not included in the Catalogue of Hazardous Chemicals (2015 Edition) and whose physical hazards have not been determined;

For the purpose of scientific research or product development, the annual output or use of chemicals exceeds 1 ton, and the physical hazard has not been determined;

Chemicals that have been listed in the Catalogue of Hazardous Chemicals (2015 Edition) are found to have new physical hazards.

Chemical physical hazard identification method

Series identification: For chemicals with similar uses, close components and no significant difference in physical hazard, chemical enterprises can apply to the identification agency for series chemical identification;

Joint identification: Multiple chemical enterprises may jointly apply for identification of the same chemical.

The main items of classification, identification and testing of hazardous chemicals are:

Category of hazardous chemicals	Identification items
Category 1 Explosives	Kernan test
	Friction sensitivity test
	Impact sensitivity test
	Time/pressure test
	thermal stability screening test
Category 2 Gas	Ignition distance test
	Enclosed space ignition test
	Foam flammability test
	Gas oxidation test
Category 3 Flammable liquid	Closed cup flash point test
	Solvent separation test
	Continuous combustion test
	Viscosity test
Category 4 Flammable solids, substances liable to spontaneous combustion, substances that emit flammable gases when exposed to water	Burning rate test
	Preliminary screening test for self-reactive substances
	Ignore solids test
	Test of ignition liquid
	Test for self-heating characteristics of substances
	Self-ignition temperature test
	Flammable gas test when exposed to water
Category 5 Oxidizing substances and organic peroxides	Oxidizing solids test
	Oxidizing liquid test
Class 8 Corrosive substances	Metal corrosion test

New cosmetics raw materials for the record testing

According to the State Drug Administration issued the "cosmetics new raw materials registration and filing data specification". Application for registration or filing requires the submission of basic information, development reports, preparation processes and quality control standards, safety evaluation and other materials.
