---The specific requirements for inherent loads have been changed, now allowing Category H to withstand 2.5 times the human body weight, and Category S to withstand 2 times, and also capable of withstanding 4 times the static load without damage.

The deformation was set and adjusted so that each support surface could withstand 2.5 times the static load calculated by the formula without damage (see 5.3).

(2008 version 5.3);

---The requirements for handrails/handrails have been changed from permanent deformation not exceeding 3% to not damaging normal use (see 5.4,.2008 version).

(5.4)

---Added dimensional requirements for footboards, footboard guardrails, and anti-slip surfaces (see 5.5,.2008 edition of 5.5);

---Added additional requirements for tiered chairs (see 5.9);

---Added additional requirements for seated steppers (see 5.10);

---The required motion frequency for temperature testing has been changed from 60 steps/min to 40 cycles/min, and a formula for calculating power has been provided.

(See 6.2, 6.3 in the.2008 edition);

---The testing requirements for inherent loads have been changed, and are now divided into two types. unassociated and associated (see 6.3, 6.4 in the.2008 version);

---A friction test has been added (see 6.5);

---The runtime requirement for the H-class durability test has been changed from running for 15 minutes and then stopping for 15 minutes to running for 20 minutes and then stopping.

Machine time 15 minutes [see 6.6.1, 6.6a (2008 edition)];

---The required motion frequency for the non-speed-correlated stepper durability test has been changed from 60 steps/min to 40 cycles/min.

The power calculation formula is given (see 6.6.3, 6.6 in the.2008 edition);

---Added operational cycle requirements for the Level A additional requirement test (see 6.7,.2008 version 6.7);

---An experiment involving going up and down stairs was added (see 6.8);

---Added testing of the braking system and the clearance between the movable steps and the ground or structure (see 6.9);

---Added additional requirements tests for seated steppers (see 6.10);

---Added test report requirements (see Chapter 7).

This document is modified to adopt ISO 20957-8.2017 "Stationary fitness equipment – Part 8.Steppers, stair climbers and other equipment with additional features".

Special safety requirements and test methods.

The technical differences between this document and ISO 20957-8.2017, and the reasons therefor, are as follows.

---ISO 20957-1 has been replaced with the normatively referenced GB/T 17498.1 to adapt to my country's technical conditions.

The following editorial changes have been made to this document.

---To harmonize with existing standards, the standard title has been changed to "Indoor stationary fitness equipment - Part 8.Steppers, stair climbers and ladders".
