1. Thickness: The minimum thickness of the glove material is specified as 0.10 mm for palm and 0.05 mm for back.
2. Tensile Strength: The tensile strength of the glove material shall be not less than 10 MPa.
3. Elongation at Break: The elongation at break of the glove material shall be not less than 300%.
4. Puncture Resistance: The glove material shall withstand a puncture test using a specified needle.

Significance and Benefits

The JIS K 6380 standard provides several benefits to manufacturers, users, and regulatory bodies:

1. Quality Assurance: The standard ensures that rubber gloves meet minimum quality and performance requirements.
2. Safety: The standard helps to ensure that rubber gloves provide adequate protection against various types of hazards.
3. Interchangeability: The standard facilitates the interchangeability of rubber gloves among different manufacturers and users.
4. Regulatory Compliance: The standard helps manufacturers to comply with regulatory requirements and industry standards.

Conclusion

The JIS K 6380 standard is an important document that specifies the requirements for rubber gloves used for general purposes. The standard provides a framework for manufacturers to design, test, and certify their products, ensuring that they meet minimum quality and performance requirements. By complying with the JIS K 6380 standard, manufacturers can ensure that their rubber gloves provide adequate protection to users and meet regulatory requirements.

Here’s an interesting, informative write-up on JIS K 6380 — tailored for engineers, quality control professionals, or anyone curious about Japanese industrial standards for rubber materials.

Key Details of JIS K 6380

This standard is the Japanese equivalent of the international standard ISO 48.

1. Scope: It describes methods for determining the hardness of rubber.

   • Method A, D, and E: Used for measuring the indentation hardness of rubber using durometers. These are the most common methods.
     • Type A: For soft to medium-hard rubber (e.g., rubber bands, tires).
     • Type D: For hard rubber and hard thermoplastics.
     • Type E: For very soft rubber/sponges.
   • Method N, H, L, and M: Used for measuring hardness using a dead-load hardness tester (IRHD - International Rubber Hardness Degrees). This method is often used for precision testing or curved surfaces.

2. Relationship to ISO 48: JIS K 6380 is largely harmonized with ISO 48 (Rubber, vulcanized or thermoplastic — Determination of hardness). If you are looking for technical specifications for a project, referring to ISO 48 will often provide the same testing parameters.

Is a "Free JIS K 6380 PDF" Legitimate?

A common search query is "jis k 6380 pdf free download." Caution is advised. JIS standards are copyrighted by the Japanese Standards Association (JSA). While some public libraries or university subscriptions offer access, most free PDFs on file-sharing sites are either:

• Outdated revisions (dangerous for compliance)
• Poor scans with illegible tables or missing pages
• Watermarked drafts that do not represent the final standard

For professional use, you should purchase the PDF directly from the JSA e-store or authorized resellers like ANSI (American National Standards Institute) or Techstreet. The cost (typically $50–$150 USD) is negligible compared to the liability of a failed gasket.

Document Analysis: JIS K 6380

Title: Rubber, vulcanized or thermoplastic — Determination of hardness Status: Current Japanese Industrial Standard (JIS) Corresponding International Standard: ISO 48-4

1. Scope and Application

This standard specifies methods for determining the hardness of vulcanized or thermoplastic rubbers. It is the primary reference document for quality control in rubber manufacturing in Japan.

• Hardness Range: It covers a wide range of hardness, from very soft rubber to hard ebonite.
• Methods Described: The standard details three primary methods for measuring hardness based on the material's properties:
  1. IRHD Method (International Rubber Hardness Degrees): Suitable for standard laboratory testing.
  2. Durometer Method (Shore Hardness): Suitable for handheld, on-site, or factory floor testing.
  3. HARDOMETER Method: Specific to Japanese contexts for softer materials.

B. Durometer (Shore A/D)

• The instrument must be calibrated against a master block.
• Procedure: The durometer is pressed firmly against the specimen.
• Timing: The reading is usually taken 3 seconds after the presser foot makes contact with the specimen.

4. Test Specimen Requirements

The standard sets strict guidelines for the sample preparation to ensure test accuracy. Materials and Construction : The standard specifies the

• Thickness:
  • For IRHD methods, the minimum thickness is typically 8 mm. If the sample is thinner, layers may be plied (stacked), provided they are smooth and flat.
  • For Shore A methods, the minimum thickness is 6 mm.
• Surface: The surface must be smooth, flat, and free from defects like bubbles, cracks, or oil stains.
• Conditioning: Specimens must be conditioned at standard laboratory temperature (usually 23°C ± 2°C) and humidity (50% ± 5%) for at least 24 hours before testing.

5. Test Apparatus and Procedure

The PDF outlines the specific equipment requirements:
