HG/T Standards

HG/T Standards

HG/T is part of China’s industry-standard system. The prefix is used for recommended chemical-industry standards, so the series is broader than footwear alone and can cover chemical products, rubber materials, coated fabrics, product specifications, and test methods.

When an HG/T document is named in a customer requirement, purchase specification, or quality plan, the exact number and edition matter. Different HG/T documents can call for different specimens, machines, conditioning steps, and result reporting.

Quick Definition

HG/T is the recommended chemical-industry standards designation used in China. Within material testing, it often appears in rubber and footwear workflows where flexing, strength, adhesion, ageing, or product-inspection checks are required.

Why HG/T Standards Matter in Testing

HG/T documents are important because they do not function as a generic label. Each designation points to a specific requirement set, test procedure, or product specification that can change the apparatus, specimen preparation, and reporting format used in the lab.

That matters especially in rubber footwear and sole work. A whole-shoe flexing method, a 90° sole-material flexing method, and a product-specification standard for rubber soles may all sit in the same HG/T series, but they do not use the same setup or produce the same type of result.

Common Materials or Application Areas Covered

HG/T spans a large part of the chemical sector, so its coverage is wider than one product category. In the material-testing and equipment-buying context, the most relevant application areas often include the following.

• Rubber footwear and whole-shoe durability evaluation.
• Sole materials, including rubber and thermoplastic-elastomer sole constructions.
• Footwear upper materials used in rubber-shoe constructions.
• Rubber or plastic coated fabrics and related adhesion or tear testing.
• Broader chemical, polymer, and rubber product inspection work where HG/T product standards are specified.

Common Test Types

Within the HG/T series, common laboratory activities connected to material testing include both method standards and product-specification checks.

• Whole-shoe repeated flexing and observation of cracking or delamination.
• Sole-material 90° flexing and crack-growth evaluation.
• Strength testing of footwear upper materials, including checks after ageing treatment where specified.
• Tear and adhesion testing for coated-fabric materials.
• Product inspection of rubber soles against a cited specification.

How to Read a HG/T Designation

In the designation, HG identifies the chemical-industry standard series in China and the added /T marks it as a recommended industry standard. The number that follows identifies the document, and many citations also include the publication year.

A citation may therefore look like HG/T 2871-2022. Some documents use part numbering, such as a numbered section or part, and some continued-valid reprints may also show a review mark in parentheses, such as an added review year.

Featured Standards / Methods / References

The HG/T series is broad, so the most useful examples are the ones that clearly connect to recurring lab work and equipment decisions.

HG/T 2411-2006(2021): This document covers 90° flexing of sole material and is commonly associated with sole-material durability and crack-growth evaluation.

HG/T 2871-2022: This document covers repeated flexing of whole rubber shoes and includes Method A and Method B for judging problems such as opening, cracking, and related flexing damage after cycling.

HG/T 6012-2022: This document covers strength testing for rubber-shoe upper synthetic-fiber materials, including assessment before and after ageing treatment.

HG/T 3082-2022: This document is a rubber-sole product standard. It is useful in buying and QA work because the cited clauses can drive which inspection and test equipment are needed for a sole program.

Standards / Methods by Application Area

Grouping HG/T documents by application area is often the easiest way to match a code with the right machine set.

Rubber footwear durability: Whole-shoe flexing work is commonly linked to HG/T 2871. This workflow focuses on repeated bending of finished footwear and post-test judgement of visible failure modes.

Sole-material flex durability: HG/T 2411 is closely connected to 90° flexing of prepared sole-material specimens. This is typically a specimen-based durability workflow rather than a whole-shoe test.

Upper-material and component evaluation: HG/T 6012 points to material-strength work on rubber-shoe upper materials and may add ageing-related comparison before final interpretation.

Coated-material evaluation: Other HG/T documents in the series cover coated-fabric tear or adhesion checks, which can shift the equipment path toward tensile frames, specialized grips, and specimen-preparation tools.

Equipment Commonly Used with These Standards / Methods / References

The right equipment depends on the exact document cited, but several machine families recur in HG/T rubber and footwear work.

Whole-shoe flexing testers: Used when the requirement calls for repeated flexing of finished footwear, especially for HG/T 2871 workflows. Typical accessories include counters, clamps, cycle controls, and visual evaluation aids.

Sole-material flexing testers: Used for 90° flexing of prepared sole specimens in HG/T 2411-style work. Typical accessories include specimen cutters, mandrels or flexing fixtures, counters, and crack-reading aids.

Tensile testing machines: Used where HG/T documents call for material-strength, tear, or adhesion measurements, including upper-material and coated-fabric work. Typical accessories include suitable grips, cutting dies, and extensibility or force-measurement support.

Conditioning and ageing equipment: Used when the method compares properties before and after ageing or when controlled sample conditioning is needed before testing.

Routine inspection tools: Product-specification documents within HG/T may also require hardness, dimensions, mass, or other routine checks, so the final setup can include smaller bench instruments alongside the main test machine.

Related Standards Organizations or Related Frameworks

HG/T is often used alongside other Chinese standards designations, depending on whether the requirement is written at national, light-industry, or petrochemical level.

GB/T: National standards in China are commonly used with HG/T when a specification combines national and industry-level requirements.

QB/T: Light-industry standards matter in footwear and consumer-product testing, especially where product-focused shoe methods sit outside the chemical-industry series.

SH/T: Petrochemical standards become relevant when a requirement is tied more closely to petrochemical materials, feedstocks, or plant-side testing.
