How we verify

1) Source hierarchy

We use sources in the following order, always preferring the higher level:

1. Binding codes: the Saudi Building Code (e.g. SBC 401 electrical, SBC 701 plumbing, SBC 602 energy conservation) and instructions from official bodies such as SASO.
2. International and regional standards: ISO, IEC, ASTM, EN and ANSI, their texts or official summaries.
3. International model codes: such as the International Plumbing Code (IPC).
4. Published technical guides from manufacturers and professional bodies: data sheets, industry councils, professional education centres.
5. Peer-reviewed research published in scientific journals.

We never use forums, advertisements or unverified content as the source of any figure.

2) Writing rules

• Every figure and specification has a source: we only write a figure or specification after matching it to its original source, each guide lists its sources at the end, with a number next to the statement each one supports, and the editorial team keeps a full reference log for each section.
• Standard vs. advice: phrases like "the standard requires" mean a documented text; "common practice" or "practical note" means professional experience, and we label it as such.
• Guidance tables are labelled: any simplified selection table says it is indicative, and that the final decision follows the manufacturer and the code.
• The binding reference in Saudi Arabia: when we present a foreign standard, we remind readers that the Saudi code is binding.
• Several sources for sensitive figures: important figures are cross-checked where possible; if sources disagree we state the most recent or most official and note the difference.
• Dead links: if a publisher removes a page, we link to an archived copy and say so.

3) What our badges and labels mean

Each badge has a condition; it does not appear otherwise:

Inside a guide we distinguish four kinds of information:

• Sourced fact: a figure, specification or regulatory text matched to its source.
• Calculator estimate: an approximate result from a stated formula and stated assumptions, not a measurement.
• Practical advice: common professional practice, labelled as such.
• Planned service: anything not yet launched is labelled so, and never presented as available.

4) Editorial workflow

1. Draft: written directly from original sources.
2. Source review: every figure and specification matched to its source, links checked.
3. Publish: with a last editorial review date when one is known.
4. Periodic review: when a new edition of a standard or regulation appears, or a report comes in.
5. Corrections log: every correction recorded with its date under the guide.

5) Safety first

In electrical, gas and structural guides we write for awareness and planning, not to teach self-execution. Any work on electrical installations or structural elements must be done by a licensed professional.

6) Review and correction

• A guide shows the date of its last real editorial review when one is known; if no trusted date is known, no other date is shown in its place. Checking sources alone is not an editorial review.
• Standards are revised periodically; we review guides when new editions are published.
• Each guide has a "Tell us" link to report an error. Every report is checked against the source, and the guide is corrected when the error is confirmed.

7) The English edition

Binaaline is written first in Arabic. The English edition is a faithful translation of the same guides, citing the same sources.
