Technical Standards Japanese: JIS, 要件, 試験方法, 適合

Core examples: JIS, 要件, 試験方法, 適合, 適用範囲, 定義, 分類, 引用規格, 測定条件, 判定基準.

Dry Japanese can be the most consequential Japanese

A standard says:

この規格は、〇〇に適用する。 試験方法は、次による。 判定基準に適合しなければならない。

The prose is dry. The effect is not. Technical standards decide whether a product, process, material, test, or document conforms.

The key principle is:

Standards Japanese must be read by scope, requirement, method, condition, and judgment.

A sentence may not be dramatic, but it may define pass/fail.

JIS

JIS

means Japanese Industrial Standards.

Related:

日本産業規格 Japanese Industrial Standards

規格 standard

規格番号 standard number

適合 conformity

JIS is a major standard system, but technical documents may also cite ISO, IEC, company standards, industry standards, or legal requirements.

Learner action: identify which standard controls the text.

適用範囲

適用範囲

means scope of application.

This section tells what the standard covers and sometimes what it excludes.

Example:

この規格は、家庭用電気機器に適用する。 This standard applies to household electrical appliances.

Learner action: scope comes first. If the standard does not apply, the rest may not govern the object.

定義

定義

means definition.

Standards define terms precisely:

この規格で用いる主な用語の定義は、次による。 The definitions of main terms used in this standard are as follows.

A familiar word may have a standard-specific meaning.

Learner action: check definitions before interpreting requirements.

分類

分類

means classification.

Standards may classify products, methods, grades, types, or conditions.

Related:

種類 types

等級 grades

区分 categories/divisions

Classification controls which requirement applies.

要件

要件

means requirement.

Related:

要求事項 requirements

必要条件 necessary conditions

性能要件 performance requirements

A requirement states what must be true.

High-force phrases:

〜しなければならない must

〜でなければならない must be

〜とする shall be / is specified as, depending context

試験方法

試験方法

means test method.

Related:

試験条件 test conditions

試験片 test piece/specimen

試験装置 test equipment

試験結果 test result

A test method defines how evidence is produced. If the method differs, results may not be comparable.

測定条件

測定条件

means measurement conditions.

Examples may include:

• temperature,
• humidity,
• equipment,
• sample preparation,
• measurement time,
• voltage,
• load,
• calibration.

Learner action: numbers are meaningful only under stated conditions.

判定基準

判定基準

means judgment criteria/pass-fail criteria.

Related:

合格 pass

不合格 fail

適合 conforming

不適合 nonconforming

判定基準 is the bridge between measurement and decision.

引用規格

引用規格

means referenced standard.

A standard may depend on other standards.

Example:

引用規格は、次に掲げる規格による。 Referenced standards are as listed below.

Learner action: a requirement may be incomplete unless the referenced standard is read.

適合

適合

means conformity/conformance.

Related:

適合する conform

適合性 conformity

適合証明 conformity certificate

不適合 nonconformity

適合 is not just “fits.” It means meeting defined requirements.

JIS

Japanese Industrial Standards.

Learner action: standard system.

要件

Requirement.

Learner action: must-satisfy condition.

試験方法

Test method.

Learner action: how evidence is produced.

適合

Conformity.

Learner action: meets standard.

適用範囲

Scope.

Learner action: what the standard covers.

定義

Definition.

Learner action: standard-specific meanings.

分類

Classification.

Learner action: type/category affects requirements.

引用規格

Referenced standard.

Learner action: external standard controls details.

測定条件

Measurement conditions.

Learner action: context for numbers.

判定基準

Judgment/pass-fail criteria.

Learner action: decision rule.

Standards-reading pass

When reading a technical standard:

1. Standard name and number.
2. Scope: 適用範囲.
3. Definitions.
4. Classification.
5. Requirement.
6. Referenced standards.
7. Test method.
8. Measurement conditions.
9. Acceptance/judgment criteria.
10. Documentation or labeling requirement.

Standards clause force table

Technical standards use dry phrasing to create requirements.

A single modal phrase can change whether something is mandatory or informative.

Requirement-method-judgment chain

Technical standards often follow this chain:

要件 what must be true

試験方法 how to test it

測定条件 under what conditions

判定基準 how to decide pass/fail

適合 result meets standard

If you skip the test method, you may misunderstand the requirement. If you skip conditions, you may misuse the measurement.

引用規格 warning

Referenced standards can carry important details.

引用規格

means the document depends on another standard. If the cited standard defines a method, material, or classification, the current text may be incomplete without it.

For compliance contexts, “I read this one page” is usually not enough.

A strong tool for this article would turn standards text into requirement cards.

Suggested functions:

1. Scope detector.
2. Definition glossary builder.
3. Requirement-force highlighter.
4. Referenced-standard tracker.
5. Test-method and condition fields.
6. Pass/fail criteria visualizer.
7. Engineering/compliance caution label.

Final rule

Technical standards Japanese is precision obligation language.

適用範囲 says what is covered. 定義 says what words mean. 要件 says what must be true. 試験方法 says how to test. 測定条件 says under what conditions. 判定基準 says pass or fail. 適合 says it meets the standard.

Read the standard before reading the number.
