First Aid EVA Kit Design Standards and Specifications

First Aid EVA Kit Design Standards and Specifications

Technical Requirements of EVA Materials in International Standards

Material Properties and Classification Standards

According to ISO 21301-1:2019, a unified naming system and specification basis have been established for EVA molding and extrusion materials. This international standard provides an authoritative framework for the classification, naming, and performance indicators of EVA materials, ensuring consistency in material quality globally.

This standard specifies in detail the key performance parameters of EVA materials, including vinyl acetate content, melt flow rate, tensile strength, elongation at break, and hardness, which directly affect the performance of the final product.

EVA Curing Degree Testing Specifications
IEC 62788-1-6:2017 specifically specifies the measurement methods and reporting requirements for the curing degree of EVA materials. This standard defines terminology, testing equipment, testing environment, sample preparation, testing procedures, and test reports, using differential scanning calorimetry (residual enthalpy and melt/freeze scheme) and gel content method to evaluate the curing state of EVA.

The standard states: “This procedure can be used by material or module manufacturers to verify the presence and activity of crosslinking additives, and also to verify the module manufacturing (lamination) process for quality and process control purposes.”

An updated version of this standard was released in 2020, further optimizing the testing methods, which is crucial for ensuring the durability and stability of EVA materials in first aid kits.

International Standard Framework for First Aid Kit Design

Overall Design Principles
While no specific international standard for EVA first aid kits was found in the search results, the standard for industrial information security emergency response toolkits (T/CPUMT 001-2022) provides a valuable reference framework. This standard specifies the toolkit’s composition and model, technical requirements, test methods, inspection rules, labeling, packaging, transportation, and storage.

These provisions are of significant reference value for the design of EVA first aid kits, especially in terms of structural integrity, functional zoning, and durability.

User-Centered Design Approach
User-centered design (UCD) approaches are becoming increasingly important in emergency response kit design. A study points out that “many home emergency kits currently on the market ignore users’ real needs and cannot effectively cope with the complexities of disaster situations.” However, using the UCD (User-Centered Development) method can better understand user needs and translate user insights into product functionality.

This method analyzes pain points and opportunities through user personas, scenario scripts, and user journey maps, ensuring the kit is truly usable and easy to use in emergency situations.

EPA First Aid Kit Professional Testing Standards
Mechanical Performance Testing: Mechanical performance testing of EVA materials should include tensile strength, tear strength, and hardness testing, conducted according to the ISO 21301 series of standards. For finished kits, abrasion resistance, drop strength, and hinge durability should also be evaluated to ensure normal use in harsh environments.

Environmental Adaptability Testing: Professional first aid kits must maintain performance under various environmental conditions. While the IEC 62788-1-1:2024 standard primarily targets photovoltaic module encapsulation materials, its testing requirements for polymer materials under environmental factors such as heat, oxygen, ultraviolet radiation, humidity, and temperature changes provide a reference for the environmental adaptability testing of first aid kits.

The kit should maintain its integrity and functionality under extreme temperatures, humidity, and UV exposure, ensuring that the contents are unaffected by the environment.

International Compliance and Certification Requirements
Regional Standard Harmonization
When designing EVA first aid kits, the regional standard requirements of the target market must be considered. For example, European standard EN 62788-1-6 is based on the IEC international standard but may have additional local requirements.

Material Safety Certification
When EVA materials are used in first aid kits, relevant safety certifications may be required, such as RoHS (Restriction of Hazardous Components Directive), REACH (Registration, Evaluation, Authorization and Restriction of Chemicals Regulation), and medical device-related certifications (if used in medical emergency scenarios).

Manufacturers should ensure that the material supply chain complies with these requirements and provide corresponding test reports and certificates.

EVA First Aid Kit Industry Best Practices
Modular Functional Design
Modern first aid kit design tends towards modular partitioning, with dedicated modules for different emergency scenarios (such as trauma, CPR, burns, etc.). Research shows that by conducting T-tests on sample data across different dimensions, common user avoidance behaviors and needs can be identified, thereby optimizing the functional module design. Ergonomic Considerations: The opening and closing mechanism, handle design, and weight distribution of the toolkit should all be optimized based on ergonomic principles. Especially in emergency situations, intuitive operation and quick access can be crucial to the success of a rescue.

The “Class I — Manual or EVA” connector design considerations mentioned in AIAA G-072-1995 guidelines, while geared towards the aerospace field, emphasize ease of use and human-computer interaction principles that are equally applicable to the design of first-aid toolkits.

Durability and Lifespan Management: The aging characteristics and product lifecycle of EVA material are key considerations in the design of professional toolkits. The test methods described in IEC 62788-1-6 can be used to assess the curing state and uniformity of the material, predict performance changes under different storage conditions, and ensure reliable use within the product’s shelf life.

Future Development Trends and Innovation Directions: With advancements in materials science and manufacturing technology, EVA first-aid toolkits are developing towards greater intelligence, lightweight design, and personalization. The new generation of first-aid kits is integrating IoT technology, providing inventory management and expiration reminders. Meanwhile, differentiated designs based on various user needs (home, automotive, outdoor, industrial) are gaining increasing importance.

Conclusion: The design and manufacture of EVA first-aid kits is a multidisciplinary and multi-standard professional field. From the selection of EVA materials to the final product inspection, strict international standards and specifications must be followed, such as ISO 21301-1 and IEC 62788-1-6.

Only by organically combining user needs, materials science, manufacturing processes, and international standards can truly reliable first-aid kits be created in critical moments, providing solid support for life safety and health protection.
