Slip Rating & Wet Pendulum Guide

A concise overview of P1–P5 slip ratings so you can align each Karimi Stone finish with the right space, moisture level and safety expectation.

OVERVIEW

P1 → P5 safety band

P1 P2 P3 P4 P5

What the Wet Pendulum Test (WPT) tells you

The WPT measures how slippery a surface becomes when wet. Each finish is given a P rating from P1 (higher slip risk) through to P5 (maximum grip). As the number increases, the expected slip resistance also increases.

RATING SCALE SNAPSHOT

From higher slip risk to maximum grip

Each Karimi Stone P icon below is your quick visual code before checking detailed applications.

P1 → P5 Left = smoother | Right = more textured

Dry circulation

Higher slip risk

For dry-only walkways and light traffic areas where water is not expected on the surface.

Light splash

Occasional moisture

Bathrooms, small kitchens and transition areas that see brief, easily managed water.

Everyday wet public

Balanced grip

Entries, amenities, undercover car parks and fresh food retail where wet floors are common.

High exposure

Wet, high traffic

Pool surrounds, communal showers and external ramps under 1:14 where water is constant.

Maximum grip

Highest safety band

Commercial kitchens, covered loading docks and pool ramps or stairs leading into water.

HOW TO READ THIS POPUP

Start with water, movement and consequence
Consider how wet the floor can get, how quickly people move, and how critical a slip could be. Then use the cards below to align each area of your project with a suitable P rating before you select a Karimi Stone finish.

TYPICAL APPLICATIONS

P1 – dry circulation
Higher slip risk when wet

For areas intended to remain dry with controlled walking speeds – such as supermarket aisles, separate shops inside centres or dry lobby and corridor zones.

Retail aisles

Dry-only entries

Light traffic

P2 – light splash
Transitional & semi-wet areas

For spaces where occasional water is expected but quickly managed – like hotel bathrooms, apartment kitchens, laundries and transition zones between wet and dry areas.

Hotel bathrooms

Apartment kitchens

Laundries

P3 – regularly wet public
Balanced everyday grip

Used where wet conditions are common – entries and access ways, toilet facilities in public buildings, undercover car parks and fresh food retail areas.

Public entries

Toilet facilities

Undercover parking

P4 – high exposure
Wet, high traffic environments

Selected for consistently wet and busy areas such as pool surrounds, communal showers, external ramps under 1:14 and service zones behind bars.

Communal showers

Light traffic

P5 – maximum grip
Demanding commercial use

For the most demanding applications: commercial kitchens, loading docks under cover, steep external ramps, swimming pool ramps and stairs leading into water.

Wet Pendulum Test (WPT)
تست آونگ یا Pendulum Test روشی استاندارد برای سنجش میزان لغزندگی سطوح سنگ و سرامیک است، خصوصاً در حالت خیس که خطرش بیشتر می‌شود. در این آزمون، دستگاهی با پاشنه‌ی لاستیکی شبیه‌سازی‌شده روی سطح خیس کشیده می‌شود و بر اساس میزان انرژی از دست‌رفته، عددی به نام BPN یا SRV به‌عنوان شاخص مقاومت در برابر لغزش ارائه می‌شود. عواملی مانند زبری یا صافی سطح، وجود گردوغبار، آب یا روغن و همچنین دمای محیط (خصوصاً در شرایط یخ‌زدگی) بر نتیجه اثر می‌گذارند. این تست به‌طور گسترده در صنعت سنگ ساختمانی برای ارزیابی ایمنی سطوح کف، فضاهای بیرونی و محل‌های پرتردد استفاده می‌شود.
