Comprehensive Guide to Determination of DINP, DIDP and DNOP in Plastic Toys Laboratory Testing Service by Eurolab

Standard-Related Information

The determination of Di-(2-ethylhexyl) phthalate (DINP), Di-isononyl phthalate (DIDP) and Di-n-octyl phthalate (DNOP) in plastic toys is governed by various international and national standards. The relevant standards that apply to this specific laboratory test are:

  • ISO 16701:2008 - Plastics - Determination of the content of phthalates

  • ASTM D4321-10 - Standard Test Method for Phthalate Content in Poly(Vinyl Chloride) (PVC)

  • EN 71:2016A12 - Safety of toys - Part 3: Specific requirements for toys placed on, or designed to be placed in, childrens mouths

  • TSE 1173 - Plastic Toys - Safety Requirements

    • These standards specify the methods and procedures for determining the content of DINP, DIDP and DNOP in plastic toys. They also outline the limits for these chemicals in different types of plastic toys.

    Standard Development Organizations

    The development of international standards is carried out by organizations such as:

  • International Organization for Standardization (ISO)

  • American Society for Testing and Materials (ASTM)

  • European Committee for Electrotechnical Standardization (CENELEC)

    • These organizations work together to develop, maintain and update the relevant standards. The standard development process involves a series of steps that include:

    1. Research and drafting

    2. Review and comment period

    3. Voting and approval

    4. Publication and maintenance

    Standard Compliance Requirements

    The compliance requirements for different industries vary depending on the country and region. Some industries, such as toys, have stricter regulations than others. For example:

  • The European Union has implemented Regulation (EU) 2018/2000, which sets limits for DINP, DIDP and DNOP in plastic toys.

  • The United States has enacted the Consumer Product Safety Improvement Act (CPSIA), which also includes provisions for phthalate content.

    • The following are some specific standard numbers and their scope:

  • ISO 16701:2008 - Plastics - Determination of the content of phthalates

    • Scope: Specifies methods for determining the content of DINP, DIDP and DNOP in polymeric materials.

  • ASTM D4321-10 - Standard Test Method for Phthalate Content in Poly(Vinyl Chloride) (PVC)

    • Scope: Describes a method for determining the phthalate content in PVC.

  • EN 71:2016A12 - Safety of toys - Part 3: Specific requirements for toys placed on, or designed to be placed in, childrens mouths

    • Scope: Specifies safety requirements for toys, including limits for DINP, DIDP and DNOP.

    • The quality assurance and quality control aspects of this test involve:

  • Calibrating and validating equipment

  • Following standard operating procedures (SOPs)

  • Maintaining accurate records and documentation

    • Test Conditions and Methodology

    The determination of DINP, DIDP and DNOP in plastic toys involves several steps:

    1. Sample preparation: Collecting and preparing the sample for testing.

    2. Testing equipment and instruments: Using specialized equipment to analyze the sample.

    3. Testing environment requirements: Maintaining a controlled environment during testing.

    4. Measurement and analysis methods: Conducting measurements and analyzing data.

    The testing parameters and conditions include:

  • Temperature: 25C 5C

  • Humidity: 60 10

  • Pressure: Atmospheric pressure

    • The measurement and analysis methods used in this test are:

  • Gas chromatography-mass spectrometry (GC-MS)

  • High-performance liquid chromatography (HPLC)

    • The calibration and validation procedures involve:

  • Calibrating equipment using certified standards

  • Validating results against certified reference materials

    • Test Results and Interpretation

    The test results provide a quantitative measure of the DINP, DIDP and DNOP content in plastic toys. The interpretation of these results involves:

  • Comparing results to standard limits

  • Identifying potential health risks associated with exposure to phthalates

  • Determining the effectiveness of measures taken to reduce phthalate content

    • The test report includes:

  • Sample identification information

  • Test methodology and procedures

  • Results and interpretation of data

  • Conclusion and recommendations for further action.

    • Conclusion

    The determination of DINP, DIDP and DNOP in plastic toys is a critical aspect of ensuring the safety and quality of these products. The standard-related information, standard requirements and needs, test conditions and methodology, and test results and interpretation all contribute to the importance of this testing.
