Geltungsbereich und Anwendbarkeit

This standard applies to safety signs used on Chinese-flagged domestic navigation ships and watercraft facilities. It covers the design, technical requirements, testing, and application of signs related to life-saving appliances and escape routes. It is mandatory for all manufacturers and operators of domestic marine vessels. It does not apply to international navigation vessels, which are subject to separate regulations.

Technische Anforderungen

This standard specifies the technical requirements for marine life-saving equipment signs, categorized into four main types: means of escape signs (MES), emergency equipment signs (EES), life-saving systems and appliances signs (LSS), and mandatory action signs (MSS). The standard mandates that sign materials must be durable, non-toxic, and non-radioactive, strictly prohibiting the use of materials that deform, deteriorate, or are flammable when exposed to water. For areas with electrical hazards, insulating materials must be utilized. Regarding shape and color, MES, EES, and LSS signs must be square or rectangular with a green background and white graphics, while MSS signs must be circular with a blue background and white graphics. The standard also defines specific requirements for luminous intensity for photoluminescent signs and sets a minimum oxygen index of 26% for plastic-based signs to ensure adequate fire resistance. Furthermore, signs intended for external use must have protection against UV and moisture aging, complying with GB/T 26443.

Prüfverfahren

The standard outlines specific testing procedures to verify compliance. Visual inspection and documentation review are required for material and appearance validation. Shape and color are verified through visual checks against specified color codes like G02 light green and PB05 sea blue. Dimensional verification involves measuring the border sizes using rulers or vernier calipers at three different positions. Fire resistance is tested according to the methods specified in GB/T 2406.1. For photoluminescent signs, luminous intensity is measured using a specific light source and illuminance meter after a 24-hour exposure period. Durability testing is conducted in accordance with GB/T 26443 to ensure long-term performance.

Häufige Fragen

What products are regulated under GB 16557-2023?

GB 16557-2023 regulates safety signs used on Chinese-flagged domestic navigation ships and watercraft facilities. It covers signs for means of escape, emergency equipment, life-saving systems, and mandatory actions.

Are there any updates from the previous version of GB 16557-2023?

Yes, compared to GB 16557-2010, the 2023 version updates the scope, adds new sign categories (MES, EES, LSS, MSS), introduces new sign graphics for various equipment, and adds technical requirements for durability and shape/color testing.

How does GB 16557-2023 differ from IMO standards?

While GB 16557-2023 aligns with international practices by referencing IMO resolutions like A.760(18) and A.1116(30) for symbols, it is specifically tailored for Chinese domestic navigation vessels and includes specific national material, color, and testing requirements.
